Miley Cyrus and Katy Perry both attended Madonna’s after-party at Hyde Lounge in Hollywood on Sunday, following the 57th Annual Grammy Awards, where the two pop stars were the life of the party as they stole the spotlight on the dance floor. But it wasn’t just Miley and Katy who were seen breaking it down together, the two hitmakers were joined by the best dancer of the evening: Kristen Wiig. Earlier in the evening, the Saturday Night Live vet took part in what may have been the best Grammys moment ever when she appeared in Sia’s performance of “Chandelier,” dancing alongside Dance Moms star Maddie Ziegler. The 41-year-old comedian surprised everyone by taking the stage with her modern dance moves before later bringing her skills to Madonna’s bash.
