Justin Bieber to star in own biopic, aged 16

Most famous faces never get to see their own movie biopics – there's an unwritten rule that you usually have to be dead before being immortalised on the big screen. Not so teen megastar Justin Bieber, whose life story is set to be filmed before he has even reached his 17th birthday. Who will play him? Well, who better than Bieber himself?

According to the Deadline blog, the as yet untitled film will be directed in3D by Davis Guggenheim, the Oscar-winning director of Al Gore's An Inconvenient Truth. Bieber himself confirmed the news via his Twitter account yesterday. The film is due out on Valentine's day 2011 and will feature performances from the Canadian singer's current tour.

Despite his youth, Bieber is spectacularly big news, having recently become the first artist to see seven songs from a debut album chart on the US Billboard Hot 100. He appears to have little in the way of acting experience, but will make his debut in September with a guest role in the hit US TV crime series CSI. Bieber will play a troubled teen who is faced with a difficult decision regarding his only brother in the show's season premiere.

If the Bieber movie seems a little premature for a singer who has only been in the limelight for little more than a year, another project will put things in perspective. The singer is also planning to publish a memoir, titled Justin Bieber: First Step 2 Forever – My Story, which will chronicle his rise to super-stardom.
