Justin Bieber is doing his bit to end bullying by donating a new song, 'Born To Be Somebody', to the trailer of forthcoming documentary Bully.
In a statement reported by MTV, Bieber said: "My fans are always up for supporting a great cause. It's one of the things I'm most proud of as an entertainer. I hope they see Bully with their friends and help start the conversation so we can end bullying."
This isn't the first time Bieber has publicly supported the film. Last month he joined Demi Lovato and over half a million other people in signing a petition which successfully got the film's rating lowered so that more people could see it.
