Watch Derek Zoolander Crash Katy Perry's Musical Instagram Performance
In the clip, Perry sings along to the familiar tune "Relax" by Frankie Goes to Hollywood when Ben Stiller's Derek Zoolander comes in behind her and says, "Hey Katy, can you not sing that song? It brings up a lot of personal issues." Stiller then exits the shot and leaves Perry staring blankly at the camera.
"FASHUN WILL HAPPUN 2.12.16. @Zoolander #Zoolander2" Perry captioned the hilarious video with a reference to the movie's release date, Feb. 16. Watch her interrupted musical performance here:
