Meet Derek Zoolander Jr.

Ben Stiller, who is currently filming the comedy sequel "Zoolander 2," posted a photo of himself on set with actor Cyrus Arnold, who plays Derek Jr. Stiller captioned the photo, writing, "Meet @cyrusarnold. Son of Derek. #Zoolander2."

Arnold reposted the Instagram photo to his own page and captioned it, "It's out!!! I am playing Ben Stiller's son in 'Zoolander 2'!! So happy to share the news with all of you!! #zoolander2 #derekjr"

There is no mention on who will play Derek Jr.'s mother. Baby Zoolander, played by Mason Webb, made a brief appearance at the end of the first film.

Stiller and Owen Wilson channeled their on-screen personas at a Valentino show during Paris Fashion Week last month.

"It was kind of surreal. It was sort of exciting," Stiller told E! News. "I mean, we've never done anything like that before, to be in an actual fashion show. That was kind of intimidating. You don't want to trip. You want to get to the end. It's like 'Green Mile.' There's no electric chair at the end. There's just starving models waiting for you, but it's definitely an intense experience."

Will Ferrell and Christine Taylor are also returning for the new film, which is set to hit theaters on Feb. 12, 2016
