RuPaul's Drag Race Season 3 contestant Stacy Layne Matthews returns for a musical collaboration with the queens of All Stars Season 4.

The queens try out their best celebrity impressions for a romantic take on Snatch Game, and guest judges Gus Kenworthy and Keiynan Lonsdale weigh in on the competition.

The All Stars get into character as litigants on an unscripted courtroom parody with New Jersey Justice Michelle Visage, and Zoe Kravitz and Erica Ash sit in as guest judges.

The All Stars put their stand-up comedy chops to the test in a eulogy-style Roast of Lady Bunny, and Cecily Strong and Yvette Nicole Brown guest-judge the competition.

The All Stars are in for a surprise when they discover that the eliminated queens have returned for a lip sync smackdown and the opportunity to re-enter the competition.

The All Stars design their own nightclubs (complete with entertainment and VIP experiences), and Rita Ora and New York City nightlife promoter Susanne Bartsch guest judge.

The All Stars give their best friends drag queen makeovers and perform a Judy Garland tribute, and Frances Bean Cobain and Ellen Pompeo sit in on the judges' panel.

The All Stars put their acting skills to the test in a "Sex and the City"-inspired mockumentary, and Felicity Huffman and Jason Wu sit in on the judges' panel.

In the final challenge of the season, the remaining girls write superhero-inspired lyrics and perform original choreography for RuPaul's "Super Queen".
