Each Monday prior to the movie's release, Bieber will release new songs exclusively through iTunes.
Last week, he unveiled the hit "HeartBreaker." He released "All That Matters" this past Monday.
"I am so excited to be involved in this movie, and so happy to be able to give back to my fans, especially during the holiday season," Bieber said in a statement Wednesday. "Jon Chu and my team have done a wonderful job creating a special moment for Beliebers worldwide and I can't wait till Christmas Day when the movie will be in theaters everywhere."
"It's no secret that Justin Bieber's name drives a lot of attention," said Braun. "But with 'Believe,' we wanted him to tell his own story, truthfully and directly. The No. 1 goal of our company is to provide global audiences with content that's not only high-quality and forward-thinking, but also authentic."
"Justin Bieber is one of the biggest stars on the planet and one of the greatest entertainers of our time," said Tom Ortenberg, chief executive officer of Open Road Films. "'Believe' will be a huge Christmas present for Bieber fans and Open Road Films couldn't be happier about delivering this special engagement to theaters."
