Justin Bieber stars in the first full trailer of 'Zoolander 2'.
The 21-year-old singer leads a star-studded cast of cameo performers in the new comedy movie, which sees Ben Stiller reprise the role of dimwitted male model Derek Zoolander.
In the new clip, the 'Boyfriend' hitmaker is seen running up walls and posing for selfies, while British actor Benedict Cumberbatch plays an androgynous model.
The famous duo are joined in the clip by the reigning Formula One World Champion Lewis Hamilton and American comedian Will Ferrell, as well as Oscar-winning actress Penelope Cruz, who is seen sporting a sexy outfit.
The clip is shot in the Italian capital Rome and features some of the most recognisable celebrity faces.
There has been much speculation surrounding the identity of the celebrities who will star in the much-discussed new movie and earlier this year, Ben Stiller confirmed he would "definitely" like to see British model Cara Delevingne make an appearance.
Meanwhile, the likes of Naomi Campbell and Jourdan Dunn, and married couple Kim Kardashian West and Kanye West, have all been linked to roles in the new film.
