It's becoming increasingly clear that the folks behind Zoolander 2 are pulling out all the stops to ensure that the sequel to the hit 2001 comedy is a smash amongst all audiences.

On Tuesday (January 19), Katy Perry teased a special appearance in the forthcoming film via her Instagram. In a 15-second Instavid, the pop titan sings along to Frankie Goes to Hollywood's "Relax," before getting interrupted by none other than Ben Stiller as his Derek Zoolander character. "Hey Katy, could you not sing that song? It brings up a lot of personal issues," he says.

Film buffs might remember that the tune was used to hypnotize Zoolander into assassinating the Prime Minister of Malaysia. Bad memories, indeed.

Last year, the Hilary Clinton supporter took a break from her massive 124-date "Prismatic Tour" to shoot the July 2015 cover of Forbes as well as "a little cameo in a movie." If KP does appear in the flick, she'll join Justin Bieber, Ariana Grande, Joe Jonas, Penelope Cruz, Kristen Wiig and many more when it comes to special appearances.
