Zoolander 2: Ben Stiller uses Instagram to confirm Justin Bieber will star in comedy sequel

Justin Bieber attempts his best "blue steel" pose as it is announced he will be joining the cast of highly anticipated movie Zoolander 2.

It has already been confirmed that the likes of Kim Kardashian and Kanye West will appear in the upcoming sequel, while Ben Stiller, Owen Wilson, Christine Taylor and Will Ferrell will reprise their roles of Derek Zoolander, Hansel, Matilda and Mugatu respectively.

But it seems like there is room for even more famous names to appear in the second instalment, as Meet The Parents star Stiller confirmed pop sensation Justin Bieber's involvement in the movie over Instagram on 29 April.

The black-and-white picture sees the 21-year-old glaring into actor Stiller's eyes as he perfects his model pout, evidently channelling his part in the movie. Fans of the Baby singer might be wondering whether the star has cut his shaggy, blond hair for the photoshoot but Bieber made sure everyone knew he was wearing a wig by reposting Stiller's image alongside the hashtag "#itsawignotmynewhair."

Bieber first sparked rumours about having some kind of role in the movie on 27 April, when he told fans on Facebook that he was "working on something big right now in Europe... He is so hot right now", which is an iconic quote spoken by one of the characters in the first film.

The Never Say Never hitmaker's part in the sequel remains a mystery and he is not the only star that Stiller has confirmed over his personal social media as having a role in Zoolander 2. Over the past few weeks, he has taken to Instagram to announce Billy Zane, Penélope Cruz, Kristen Wiig and Fred Armisen are also further additions to the ever-expanding roster.

Zoolander 2 is currently filming in Los Angeles and will hit cinemas in 2016, 15 years after the original. It is said to follow Derek as he attempts to juggle fatherhood while his and Hansel's modelling careers are challenged when an opposing agency attempts to push them out of the business.
