The Voice recruited a number of stars to add firepower to the show's season finale last night. The high-flying group including Missy Elliott, who played her new single "WTF" (a collaboration with Voice judge Pharrell). The performance incorporated many of the best aspects of the video—the disco-ball suit, the hand puppets—and some new innovations: notably a massive subway-themed set complete with trains, turnstiles, and a kiosk labelled "the WTF station."
Missy wasn't the only famous guest. Justin Bieber stopped by to play "Sorry"—starting the song alone behind a grand piano before adding a beat and a slew of dancers—and the Weeknd contributed a medley of his three biggest hits. Watch below, and find out how Missy's disco ball suit got made.
