Singer Justin Bieber, who has lent his single Born to be somebody to a documentary that talks about bullying in schools, says he too was tormented as a child.
"I was bullied. Most people in their lifetime have been bullied at some point. I think that it's about time that people start making a change," he said on the show Showbiz Tonight.
The documentary is titled Bully and looks at the issue through the eyes of five youngsters. The singer believes it has the potential to make a real difference, reports contactmusic.com.
"A lot of the time, principals let it go, or teachers let it go, or other students just let it go, but I think this movie's really powerful and can help change a lot of lives," said the 18-year-old.
Meanwhile, he urges those who witness bullying, as well as those who experience it first-hand, to share the problem with someone and seek help.
