Justin Bieber isn't a fan of bullying

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.
