Scooter Braun, Justin Bieber and Usher

The singer and his creative counterparts gathered at Regal Cinemas in L.A.Live on Dec. 18 for the world premiere of Believe. Directed by Jon Chu, the documentary embraces some (though not all) of the controversy in the superstar's evolution: it shows a particularly vulnerable Bieber — still reeling from a nasty run-in with the paparazzi in March, a crushing breakup with longtime girlfriend Selena Gomez and the death of Bieber superfan Avalanna Routh of cancer at age 6, which shook him to the core. 

Usher

The R&B singer who initially signed Bieber in 2007 came out to the Los Angeles event to continue his support.

Justin Bieber

Jon Chu

The director of G.I. Joe: Retaliation and Bieber's 2011 documentary Never Say Never told THR that the movie is an illumination of the unreality of Bieber's life: "What's compelling is to see Justin not as an object for us to judge, to harp on and destroy but somebody whom we have responsibility for because we ultimately put him there. We click on those links. We fuel that fire."

Bieber and His Family

The singer was all smiles as he posed with his mother, Pattie Mallette, and grandparents at the world premiere of Believe.

Jaden Smith
