In the first show of the new series, Perez is joined by global phenomenon and close friend Lady Gaga as they spend some truly unique time together in not one, but two different continents. Beginning their journey in Hollywood the pair also jet off to Sydney, Australia for the most extraordinary access that only these two best friends can deliver.

The show features deliciously private and exclusive interviews, antics and moments, from the close friends cooking together in pyjamas to behind-the-scenes at performance dress rehearsals and backstage concert moments. Perez Hilton's access to Lady Gaga is unprecedented; it’s an hour of Lady GaGa, as you've never seen her before.

Tonight, superstar Katy Perry invites Perez to have an exclusive peak behind the scenes of her latest video for new single “The One That Got Away.” He then joins the pop superstar on her UK tour and is treated to exclusive access to her closed set. The pair also get up close and personal discussing topics ranging from her husband Russell Brand, her early Christian music career and her love of touring.

Perez Hilton said: ""I have known Katy very well for over 4years now, and I'm very excited, pleased and proud to be able to show ITV2 viewers the Katy I know! Raw, real and funny - we go behind the glitz and the glamour of being a global superstar and get to the heart of this California girl. And, of course, we talk a lot about Russell Brand! It's a MUST-watch interview!"

tagging along with Perez and Enrique as they travel together to the famous Staples Center in downtown Los Angeles where Enrique who has been on tour with Pitbull and Prince Royce for the past 12 months will be performing to over 20,000 screaming fans. Get up close and personal like only Perez can while they chat about everything from the old-school tape recorder he still carries around (and has on him) to write songs with to his ‘low maintenance’ attitude and lack of diva demands… all he wants before a show is a rum and coke to ease his nerves and this star’s wardrobe consists of a duffle bag that he carries around himself. Lady Gaga it is not. From backstage banter to a fan meet and greet you will have a front row seat for it all.
