Canadian teen sensation Justin Bieber has dropped a new teaser trailer for his forthcoming new movie, 'Believe', and he can be seen getting emotional while talking about his behaviour. 

In this new preview for the film, which will hit cinemas on Christmas Day in the USA (December 25), Bieber addresses his aggressive reaction to a photographer in London earlier this year and a tear runs down his cheek as he talks about his career. He says:

"When you've reached a certain point in life, there are people out there waiting to see you fall. But rather than let gravity take you down, sometimes you have to take matters into your own hands ... and fly."

Jon Chu, the film's director, added to MTV News: "I think a lot of people don't know what this movie is. What more story can you tell of the Justin Bieber story? And there's so much that has happened this year and last year, building the tour and his personal life, that we get to delve into," he shared about the release. "And you get to see the truth." Watch the new teaser clip below:
