Canadian pop-sensation Justin Bieber has treated fans to a teaser-trailer of his forthcoming 3D movie.

The film, ‘Never Say Never’, goes behind the scenes of Bieber’s life as a pop star as well as using footage of his earlier childhood years – shot by his mother – to trace his rise to stardom.

Speaking to MTV, director John Chu explained that the footage would lend the film a unique approach. He said Bieber belonged to “one of the very few generations that have been able to be shot from when they were a kid to a teenager”.

‘Never Say Never’ is set for release on Valentines Day 2011, and you can watch the trailer below:
