Thousands of fans turned out Wednesday night for the premiere of Justin Bieber 's new concert documentary, Believe , in Los Angeles. He brought some of them to tears as he walked the purple carpet at the L.A. Live complex -- a little late, naturally, wearing sunglasses and a red suit with a white, untucked shirt.
Believe contains concert footage and also documents some of Justin's well-publicized personal problems. His manager, Scooter Braun , acknowledged to ABC News Radio that the pop star has made some mistakes in the past year. He added, "If you put a camera on me or you at 19, we probably wouldn't be so proud right now. But that's not an excuse."
Director Jon M. Chu said that while Justin can be a troublemaker, "he's like the younger brother who always gets away with it."
Among the stars who made appearances at the premiere: Justin's mentor Usher , Jaden Smith , Kylie Jenner , Law & Order: SVU actor Christopher Meloni and his daughter, and Anchorman 2 star Meagan Good .
Justin Bieber's Believe opens Christmas Day.
