Watch Justin Bieber in Ben Stiller's Zoolander 2 trailer
Canadian popstar Justin Bieber is just one of those celebrities who stars in the film, and he even does Derek's trademark Blue Steel pose.
Incredibly, it's been 15 years since the original film (we know, time flies), but Christine Taylor, Will Ferrell, and Billy Zane all return for the sequel.
Derek, once the world's most famous model, returns to the fashion scene with Hansel (Owen Wilson), but they both find that the industry has moved on without them.
Derek and Hansel soon find themselves in competition with an opposing company attempting to take them out from the business. And it's not long before they're on a mission to stop someone "trying to kill the world's most beautiful people", which includes Justin, Miley Cyrus and Usher.
The new supporting cast includes Penélope Cruz and Benedict Cumberbatch.
Zoolander 2 was shot in Rome over three months earlier this year after Ben and Owen appeared at Paris Fashion Week dressed in character.
Zoolander 2 hits cinemas on 12 February 2016.
