"Zoolander 2" is gearing up for its big premiere next month and fans cannot wait to see Ben Stiller reprise his role as international male model Derek Zoolander.

This month, the film continues to innovate as it releases mock ads to promote the upcoming movie, which includes a fake fragrance ad and a FIAT commercial that aired at the Golden Globe Awards. Zoolander even nabbed his first Vogue cover with Valentina Valencia (Penelope Cruz), and now, even Katy Perry has joined in on the "Zoolander" fun as she took to Instagram to post a short video which teases her possible appearance in the film.

In Perry's video, she is seen singing along to the first "Zoolander" film's unofficial theme song, "Relax," by Frankie Goes to Hollywood. Later, Stiller, dressed as his character, appears behind the "Teenage Dream" singer and says, "Hey Katy, could you not sing that song? It brings up a lot of personal issues."

In the first film, the song was used as a trigger to goad Zoolander, who was hypnotized, to kill the Prime Minister of Malaysia.

According to Billboard, Perry first teased the cameo last year while the singer was in Italy. Apart from the singer, other celebrities who will reportedly make appearances in the film include Justin Bieber, Joe Jonas, Ariana Grande, Kim Kardashian, Kanye West, Susan Sarandon, Lewis Hamilton, Olivia Munn, and Willie Nelson.

Last week, Stiller also participated in a Q&A with Vogue as the magazine visited Derek in his New York apartment. The clip titled "73 Qs with Derek Zoolander" featured Derek answering back to back questions about modeling and his life in New York and he also gave a tour of his luxe pad.

"I'm here to ask you 73 questions," says the interviewer.

"Well, I only have nine answers...so I guess I'm gonna need...more?" said Derek.

"Zoolander 2" premieres on Feb. 12.
