Usher Says Fans Will 'See The Truth' About Justin Bieber In 'Believe'

Usher and manager Scooter Braun talk about the singer's 'shocking' vulnerability in the documentary

LOS ANGELES — He's been photographed all over the world without his shirt on, made tabloid headlines for scuffling with the paparazzi and had a very publicized breakup, but 2013 has been a quiet year for Justin Bieber, in the sense that he hasn't done many interviews with the media.

But now, he's breaking that silence with his "Believe" documentary, which hits theaters Christmas Day. In the documentary, directed by Jon M. Chu, Bieber candidly and emotionally addresses fans about love, heartbreak and certain headline-grabbing incidents, showing fans a side of him that not many have seen.

"He's more vulnerable in this movie than any interview he's ever done, to the point where he breaks down at one point," Scooter Braun told MTV News at the "Believe" premiere in Los Angeles on Wednesday (December 18). "And I think the humanity of it is what's going to be so shocking."

What also may be shocking to fans is just how much Justin has grown up since his first film, "Never Say Never," and just how he is dealing with growing up while the world is watching, something that his mentor, Usher, knows all too well.

"With success comes great responsibility. And being able to grow up in it and unfortunately be analyzed in front of the world for just growing up, I think they will be able to see the truth," Usher said. "And they can make an assessment based off of what his reality looks like."

And, even though Justin may or may not be joking about retirement, his reality is looking very bright, with Scooter assuring fans that Justin still has a lot more work to accomplish, both musically and personally.

"It's a work in progress; I'm not done yet," Scooter said. "He's not done yet and I expect him to make great decisions and then make mistakes; that's being human. And I think our job is to continue to care and be there for him and let him be there for all these kids."
