The video begins with Spears appearing bored in class at high school. Her assistant Felicia Culotta played the role of Spears's teacher. When the bell rings, Spears runs out into the hall and begins a choreographed dance in the corridor. After this, Spears is outside, now adorned in a pink athletic outfit, and seen in a car. Along with a couple of other students, she performs a number of gymnastic moves before heading back inside. She is then sitting on the bleachers in the gymnasium watching a basketball game, and she dances in the gymnasium. Her love interest is revealed sitting close to her, played by her real-life cousin Chad.

The video begins with Spears, in a long sleeveless white dress, walking barefoot through a lawn to a telescope, and looking through it. The concept was later changed to a man and a dog walking on the beach, portraying the singer as the girl next door, watching her love interest, played by model Chad Cole, from afar. The beach location was kept, and the music video intercuts with scenes of Spears' dancing on the Paradise Cove pier with her dancers dressed all in beach-friendly white attire, then Spears sits near a car. A writer of Rolling Stone noted the video is best known for "purifying the sexy persona Spears introduced in the '... Baby One More Time' video".

The video opens with Spears as a waitress of a dance club. She then goes with other waitresses to their dressing room, where they finish their makeup and change costumes. Spears, now wearing a sexy, green sequined outfit, goes through the corridor to the dance floor with her friends, and starts to perform a high-profile choreography, including a chair dance sequence referencing Janet Jackson's "Miss You Much" video, which Spears also referenced in live performances of the song on the Crazy 2k Tour. Scenes of Spears singing in front of a shining orange sign with the word "CRAZY" are also seen throughout the video. On August 24, 1999, the music video debuted at number four on Total Request Live. It is the longest running by a female artist on TRL, staying on the top ten for seventy-three days. The video was nominated on the category of Best Dance Video on the 2000 MTV Video Music Awards; it lost, however, to Jennifer Lopez's "Waiting for Tonight" (1999).

The narrative of the video shows Spears dreaming as she sleeps in her room. As the dream begins, Spears is shown in a blue and silver futuristic room with several different levels, where she sings and walks around, and puts her feet on the wall while wearing a shiny silver outfit. MTV news reporter Ellen Thompson considered it the sexiest moment of the music video. As the video continues, Spears is seen on top of the apartment building she lives in, performing a dance segment in a red top and black skirt with a few backup dancers. The following scenes shows the singer wearing white clothes and singing in the room in which she is sleeping, while her love interest comes into her room to see her. Together, they start a pillow fight that shortly ends after Spears is shown again in her room still sleeping, however, now with a smile upon her face. A longer dance segment intercalates with all the scenes during the whole video.

The music video portrays Spears packing up her belongings, as she readies herself to move away from home, and feeling upset because she knows that she is going to miss her first love. Throughout the video, scenes of the couple's past are also seen and Spears is sitting on a tire swing, including one where they climb up onto a windmill, with Spears singing the song, and Spears is standing by a billboard that reads "Welcome to Cedar Springs Gardens" similar to the video "Lucky". Before the end of the video, Spears is waiting at a bus stop while, at the same time, her first love is driving to come see her one last time. However, by the time he finally gets there, Spears had left him behind and taken the bus.

The music video begins with a brief scene of an astronaut on Mars uncovering a stone slate featuring the cover of the album Oops!... I Did It Again. The ground begins to shake as a large stage rises from the ground. Spears, with long, straight hair, then descends from a platform onto a stage in a red bodysuit as the track begins to play. As she continues to sing and dance, she suspends the astronaut mid-air above her. Interspersed throughout the video are scenes of Spears wearing a midriff-baring white top and skirt, lying barefoot on a white web pad with backup dancers on the ground around her. During the bridge, as a symbol of his love for her, the astronaut gifts Spears with the Heart of the Ocean, the blue diamond from the blockbuster film Titanic. Spears comments "Aww, you shouldn't have" and walks away, the astronaut shrugs and leaves. The video concludes as Spears and her performers continue to dance.

The video begins with Spears telling a story about a famous Hollywood actress named Lucky. As beautiful and rich as she is, on set she sits on the star-shape in the sky, as she is acting, she is looking quite distressed. After the first chorus, she goes to the hotel mansion to the flowers, then she leaves and sits down and gets a mirror. Lucky is then seen in a shiny silver evening gown at the Oscars accepting her Academy Award for Best Actress. Lucky looks happy as she accepts it and smiles at her fans but is soon revealed that this is not true happiness. She makes her way away from her screaming fans and back into her limo, where she unexpectedly finds an ornate hand mirror that was used on the film set. She looks back to the crowd to see who has left it and sees Spears leaning forward in the crowd. The limo drives away, leaving Spears behind on the red carpet.

The video begins with a closed caption that reads "Britney Spears – Stronger", amidst the sound of a storm. At the beginning of the first verse, Spears starts dancing with an Emeco 1006-style chair in front of a black background. The second half of the video finds Spears driving away from the party in a classic Ford Mustang car during a thunderstorm; however, before long, her car goes into a spin out after she swerves to avoid a chair tossed in front of her from the storm, then stops on the very edge of the bridge. After recovering from the shock of it, she is forced to continue walking on in the rain.

The video begins with Spears and her boyfriend in a hammock. Cuts of her cuddling with her love interest beside a fire are also included. We also see her and her boyfriend on the seashore doing a love scene. Inside a tiki hut, Spears exclaims the words she wants her boyfriend to know. In the second half of the video, she is seen on a tree where her boyfriend reaches for her. There are also scenes where she is running on the beach and her boyfriend is chasing after her. Spears wears only a bikini top and a pair of cutoff shorts during the whole video, going barefoot throughout.

In the video, Spears and her backup dancers employ the same choreography and sing while looking over a balcony at cars down in the distance. Spears is portrayed as a slave to the music, dancing all day until she and the backup dancers are sweaty and near dehydration, forcing them to search for water — Spears is then seen standing by a mirror at the sink.

On October 30, 2001, a group of popular recording artists under the name "Artists Against AIDS Worldwide" released a single containing multiple versions of "What's Going On" to benefit AIDS programs in Africa and other impoverished regions. The single contains "What's Going On" along with eight additional remixes. The song was recorded shortly before the September 11, 2001 attacks, and it was decided afterwards that a portion of the song's proceeds would benefit the American Red Cross' September 11 fund as well.

It begins with Spears driving away from the paparazzi, with a part of the instrumental version of the song "Bombastic Love", featured on the album Britney, playing. She makes her way into an alleyway and decides to enter an abandoned factory, hoping her pursuers will be thrown off course. When she enters the building she begins to dance her way around the warehouse. Spears' dancers, having spotted her walking into the factory, follow her inside. They find Spears dancing around and joke about it, before heading into a heavy dance routine. Towards the end of the video, segments of Spears in a room with walls covered in pictures and articles about herself are also shown. These walls move in and out before the video ends, signifying that she is "overprotected". At the end of the video, Britney walks to a wall, and exits the building.

The video primarily consists of Spears, whilst wearing cowboy boots, performing the song whilst standing on the edge of a cliff, and inside a slot canyon: despite her "trepidation" and heavy winds which "almost dropped [her] over", she performed the scene without a safety cable. Isham praised Spears' attitude to the filming of the scene, claiming that she "had not a blink of fear" during the shoot, Spears is sitting on top of a cliff, surrounded by cliffs.

The video opens with Spears and her friends in a hotel room, where a tabloid reporter on television criticizes her for the sexy, revealing outfits she is often seen wearing publicly. Spears, determined to be self-sufficient and unaffected by media comments, then makes a phone call to her bodyguard, and using a cloth to disguise the sound of her voice, coaxes him to leave the area so that her group may sneak out of the hotel and enjoy the day. They run into an elevator and fool around briefly with the security cameras before going up to the main lobby. A strut down the lobby of the hotel and a short dance sequence follows. As they leave the hotel, they follow towards the dance club. However, before they arrive, they are caught in an alley by several paparazzi, and start to perform a dance routine in the middle of the rain. As they make their entrance, they are dripping wet, an image which makes for more sensationalist fodder for the tabloid reporter.

The video begins in black and white and switches to and from color throughout. It was shot at The Inn, a bar in Long Beach, New York. The video was ranked at number two on the 100 Best Videos of 2002 list during MTV Latin America's countdown.

In the video, a man (DJ Qualls) tries to get into a castle which is hosting a party being attended by Spears. When the security guards refuse to grant him access because he's not on the guest list, he begins to scream for Spears (after shouting that he had Fruity Pebbles with P. Diddy). As the music starts, Spears, readying herself for the party in one of the castle's towers, is dancing with a group of women. The scene shifts to a castle courtyard, where Spears and a man are sit at opposite ends of a long table. Following this, Spears walks around a pool, in which she sees a man (Justin Bruening) swimming. As they begin to interact with each other, Pharrell is at the bar with a woman. Spears walks over to him and they begin to talk. Following this, Spears dances with a group of people, including Mike Myers as Austin Powers. Actors Jason Priestley, Justin Bruening and Taye Diggs also make cameo appearances in the video.

The video starts with Spears going into a New York nightclub. Madonna, who is in a room filled with men smoking cigars, observes her from television monitors throughout the club. This is followed with Spears performing a dance routine inside a blacklight paint graffiti room, and the two women dancing around a metal bedframe. Spears then begins chasing Madonna in a wooden-like maze, and the latter enters a room covered with fallen leaves and stands in a swing. Once Spears finds the room, Madonna is nowhere to be found.

Spears appears with blonde hair dressed as a flight attendant, lifting the in-flight intercom as if on a phone call. After serving some of the passengers, she "accidentally" spills a drink into the lap of a seated male passenger; later beckoning a middle-aged, overweight, bespectacled male passenger to the bathroom where she seduces him. Spears then appears, completely re-dressed, and takes a ride on the back of a Ducati 999. Spears then enters Toxic Industries and gains access to a vault from which she steals a vial of green poison. The action narrative is repeatedly intercut with scenes of Spears, on all fours on the floor, wearing only diamonds.

It features Spears as a pop star fighting with a male companion as she is hounded by paparazzi. She starts to drown in her bathtub after bleeding from a head wound. In the hospital, doctors fail to resuscitate her, while simultaneously a child is born in the next room.

The music video begins with Spears driving a Porsche 928 at high speed in the Hollywood Hills. She crashes through a fence and lands into a pool inside a manor where a party is taking place. She emerges from the water and crawls in top of the car to sing the first verse. Spears' brother, Bryan, makes a cameo in these scenes. After she leaves the pool, she enters the manor and passes couples making out around her. She appears in a stainless steel kitchen, where a maid cuts the straps of her black wet dress. In the next scene, she walks into a study in which her then-fiancé, Kevin Federline, is smoking and watching a black-and-white video of Spears on a projection screen

In the music video, Spears wears a pink midriff T-shirt reading "Love Boat" and a pin capelet going to a club named Hole in the Wall with four blond bandmates. During the first verse, they fly in a pink Hummer and move their heads to the beat on the song, while Spears puts the truck on autopilot. The Hummer's dashboard has a Louis Vuitton pattern. They finally arrive to the club and dance in the dancefloor while being stared at by other people. Near the end of the video, Spears and her bandmates start performing on a stage

The music video features a pregnant Spears lying in bed and walking around a house while singing to her unborn child. She also gazes through the window at the Roman sculptures in the garden.

The video begins with a blonde Spears sitting and laughing in a bar with two female friends, but stops to look at a brunette Spears calling out to her on a small stage in front of them, wearing a leather vest, a studded belt, panties and fishnet stockings while sporting a tattoo on her biceps. She dances erotically around a pole and up against a mirror. Throughout the video, she continues to dance and flip her hair while special effects lights flash around her as the camera moves slightly in and out of focus to the beat of the song. The video's light systems change from black and white with aura-like blue and pink hues to full-blown color.

The video begins with four blonde women changing their clothes, putting make up on and dancing in a bedroom. Outside, several paparazzi are taking pictures of the situation through the window. Spears appears in front of a multi-colored, illuminated background wearing a short brown fur vest, a sequined black bra and ripped low-rise jeans.

Then they enter a nightclub, with Spears wearing a purple satin dress. Spears starts flirting with a man and guides him into the women's bathroom, where she discovers he has a hidden camera in his chest. She writes "Sucker" in his forehead. There is a dance sequence until the song ends, in which Spears and the four women dance in the bathroom.

The video begins with Spears wearing a short black bodysuit and knee-high black boots, standing on the roofs of a futuristic city. As the first verse begins, she breaks into a research facility and battles with suited henchmen. Spears ends up gaining access to a highly secured laboratory and walks through aisles of clones held in liquid cocoons. She sees that one is a clone of her, kisses her and plants a bomb on the tank. After this, Spears infiltrates the base of the apparent villain, kissing him, and then destroying him, revealing him to be a robot also. From there, she dodges a bullet and sets off a panic among the newly arrived henchmen, meanwhile the bomb's timer runs lower and lower. Next, there is a wide shot of the building exploding, while Spears is jumping and "Victory" is depicted on the side of the structure. The video ends with the phrase "To be continued...".

During the introduction, Spears is naked and smiling in a sauna, while covering herself with her hands. These scenes are seen throughout the video. When the first verse begins, the official version of Spears wearing a slip nightgown is making breakfast for her boyfriend (Brandon Stoughton) as he gets ready for work. When he is at the office, he sees a new secretary, which is actually Spears in disguise wearing horn-rimmed glasses and a pencil skirt. She starts dancing in front of him and sings the chorus. She makes him follow her into the photocopier, where she photocopies her buttocks.

Then, Spears is disguised as a red-haired, tattooed waitress in a restaurant. She dances around him with her dancers and plays with him over the kitchen counter. After this, her boyfriend is seen getting driven home by Spears, disguised as a chauffeur. She starts to kiss him, driving the car with her heel until both get home.

The video begins with Spears at a vanity, putting Curious on and earrings by Bulgari. She is then seen holding a top hat in front of her face, while doves fly out of another hat. Spears starts singing in the vanity but stands up and puts on a ringmaster jacket. She walks through an aisle while dancing suggestively with several circus dancers. Throughout the video, there are interspersed scenes of different circus performers, including ribbon dancers, contortionists, clowns and a mime on stilts.

This is followed by a group dance scene in the middle of a circus ring, where Spears wears the ringmaster jacket, sequined hot pants and a feathered top hat.

Spears starts singing while sitting on the edge of a bed while the people that surround her are getting dressed. She gets up and looks out the window. As the first verse ends, she picks up a pair of panties from the floor, recalling her personal struggles and the "Piece of Me" video. She dances with four male dancers in the first chorus. During the second chorus, she dances with four other female dancers dressed in cheerleading outfits, while many men are watching them dance. The screen fades to white and Spears begins to change into a conservative 1950s-inspired housewife outfit. As the chorus begins again, she comes out of her bedroom. She walks down the stairs, with dancers surrounding her and a woman gives her a potholder, which she uses to pick up a pie.

Until the end of the second chorus, we see scenes of Spears singing and watching the polo player as he gets ready. When the bridge begins, Spears arrives at a match wearing a white dress and a large hat. When the match ends, she leaves and the second man follows her. They flirt inside a hallway and leave. Her boyfriend notices her absence, walks into the hallway and sees her necklace on the floor. The video ends with Spears and the second man walking into the sunset.

The video begins with an animated Danja saying his introduction of the song, while paparazzi are in the background taking several pictures. Then, we see an animated Spears jumping into her rocket ship, flying and avoiding several paparazzi that are following her. She hides on another planet, turning all the lights of it on as she walks, and escaping the paparazzi that later appear to stalk her. However, Spears manages to avoid them, flying away into space in her rocket ship again, but this time exploding the planet and "killing all the lights" of it maneuvering a joystick.
