While most people over 30 are still unsure exactly what a Justin Bieber is, to the tween crowd he’s, like, oh my god, just so dreamy. From Youtube sensation to No.1 artist, the 16-year-old has certainly had an incredible rise to face in a very short space of time, plucked from obscurity in Canada after posting videos of himself singing on the web. So to cash in on the phenomenon, Paramount has put together the 3D flick Never Say Never, which is part concert movie and part documentary about his Justin’s short life (with plenty of ‘believe in youself’ and ‘live your dream’ messages chucked in). While it only started shooting a few weeks ago, the movie will be in cinemas in February, and now the trailer has shown up. So if you’re an 8-16 year old girl, click below and prepare to swoon, while everyone else can watch the promo and wonder what all the Bieber-ing fuss is about.
