Dreams can come true – no really, they can.

In the space of two years, 16-year-old Justin Bieber has become pop music’s cutest and brightest young thing, inspiring the kind of ear drum-perforating hysteria that greeted The Beatles and Take That in their heyday.

Caught in the eye of a storm, admittedly of his own making, the teenage singer-songwriter from Ontario in Canada seems remarkably down to earth and unaffected by the hordes of fans, who track his every move via social networking sites.

That wholesome image as the boy-next-door is reinforced by Justin Bieber: Never Say Never 3D, a life-affirming behind the scenes documentary about the boy wonder’s rise to fame culminating in his first concert at Madison Square Gardens in New York.

If you believe Jon Chu’s film – and let us not forget this is a recording company marketing tool to preach to the Beliebers and swell the flock – the singer is well protected from the media glare by a team of people, which resembles one big, happy family.

So you have a tour bus crammed with bodyguard Kenny Hamilton, who doesn’t leave Justin’s side, vocal coach Jan Smith, stylist Ryan Good, tour general manager Allison Kaye and manager Scooter, who gets all misty-eyed when he says to camera: ‘To think, the 12-year-old kid I found on YouTube is going to be at the Garden…’ The boy’s father appears briefly but the film glosses over the breakdown of the relationship with Justin’s mother Pattie Mallette, who has raised him single-handedly since she was 18.

In heart-warming scenes, Ryan and Allison find youngsters who weren’t able to get tickets and surprise them with front row seats as a thank you for creating hype when US radio stations stubbornly refused to play his music.

Chu structures his film as a diary of the 10 days leading up to the New York concert, during which time Justin’s vocal chords become inflamed.

One date on the tour is cancelled, stoking anxiety that the youngster might not be fit to perform, providing the necessary dramatic tension.

YouTube videos, home movies and photographs are intercut with interviews with his ardent fans.

‘I think about him 99 percent of my life,’ swoons one little girl.

‘One day I tweeted him 100 times,’ blushes another.

‘I want to marry Justin Bieber.

We WILL be husband and wife,’ emphatically states a third, suggesting in a few years she could be served with a restraining order.

Concert footage attests to Bieber’s ability to sing live including ‘U Smile’ with backing from Boyz II Men, a duet of ‘Overboard’ with Miley Cyrus, a remix of ‘Somebody To Love’ featuring Usher and the infuriatingly catchy ‘Baby’.

Call a doctor – we may have contracted Bieber fever.
