Katy Perry is taking over the Saturday Night Live stage! The 37-year-old entertainer took to the stage of the NBC sketch comedy series on Saturday (January 29) for two out of this world performances. Click inside to watch her two performances… For her first performance, Katy came out on stage in a red leather outfit and a mushroom top hot as she performed her new single “When I’m Gone.” Joining Katy on stage was her collaborator Alesso and a few dancers dressed up as mushrooms, who occasionally flashed Alice in Wonderland-esque signs that read “Eat Me.” Later in the show, Katy returned to the stage in a fluffy and ruffled baby blue dress for a performance of her song “Never Have I Ever.” If you missed it, an NFL superstar made a surprise appearance on SNL tonight!
