Justin Bieber brought out the Christmas red for the world premiere of his documentary Believe on Wednesday, Dec. 18, held in Los Angeles, Calif.

Sporting a mustache and black shades, the 19-year-old posed for photographers on the purple carpet in front of Regal LA Live. He wore a white shirt under a red suit and added on the jewels with a gold watch, matching chain and earring. The Canadian also stopped to take photos with his mentor Usher, who makes a cameo in the film by talking about Bieber's career thus far.

Kylie Jenner, Jaden Smith, Usher, Christopher Meloni, Casper Smart and Harry Shum were among the guests in attendance at the premiere, according to E! News. Also showing up to watch the movie was Paul Walker's daughter Meadow, marking her first public appearance since her father died on Nov. 30.

Sources confirmed that the teen arrived in one of the caravan of vehicles that took Bieber and his entourage to the event, but she did not walk the red carpet. She and Bieber met at one of his concerts, according to the news outlet.

Believe is the second docu-film directed by Jon M. Chu about Bieber's rise to fame. The movie features interviews with the singer, his manager Scooter Braun, his mother Pattie Mallette, Usher, Mike Posner, Will.i.am, Kenny Hamilton and Rodney Jerkins.

Believe shows Bieber backstage during his worldwide tour and also interviews with the All That Matters singer speaking about falling in love and breaking up, the paparazzi and more.

Guests of the premiere were asked to bring new and unwrapped toys to be handed out to underprivileged children by Radio Disney and ABC7's Spark of Love.

Believe is in theaters on Christmas Day.
