Justin Bieber’s song “Born To Be Somebody” was featured in the trailer for “Bully“, a documentary that shines a light on the growing problem of bullying.

In a surprising admission, Bieber revealed that he himself was bullied in school. “I was bullied,” Bieber tells Showbiz Tonight. “Most people in their lifetime have been bullied at some point. I think that it’s about time that people start making a change.”

While he feels that a lot of people have ignored the problem, he also believes that this film can make a difference in how people view the growing issue.

The documentary which went on a limited release in March 30 was originally unrated, but has now received a PG-13 rating to reach the younger intended audience.
