Demi Lovato has joined forces with Ellen DeGeneres to have, Bully, a documentary about bullying shown to as many people as possible.

The film is currently rated R and Lovato and DeGeneres are teaming up with Michigan high school student Katy Butler to change the rating to PG 13.

Butler, who began the petition at Change.org, has experienced severe bullying.

“When I was in 7th grade, a few guys came up behind me while putting my books in my locker. They called me names and asked me why I even bothered to show my face at school because no one liked me. I ignored them because I was scared of what else they might say and who else they might tell if I stood up to them,” Butler writes. “When I went to shut my locker, they pushed me against the wall. Then they slammed my locker shut on my hand, breaking my fourth finger. I held back tears while I watched them run away laughing. I didn’t know what to do so I stood there, alone and afraid.”

The film, which will be released March 30, follows a young boy who is bullied.

“I feel kind of nervous going to school. I like learning but I have trouble with making friends,” he says.

With 13 million kids being bullied in the U.S. this year, the film gives footage of what bullying is really like. Showing news coverage from 11-year-old Ty Field’s suicide in Perkins, Oklahoma, the story hits home.

“Some kids told him he’s worthless, to go hang himself and I think he got to the point where enough was enough,” one man said.

In an interview with Ellen DeGeneres last year, Taylor Swift says she was bullied as a kid.

“I remember when I was in school, the whole reason I started writing songs was [because] I was alone a lot of the time,” Swift said. “I’d sit there in school and I’d be hearing people [say], ‘Oh my God this party we’re going to is going to be so awesome on Friday. Everyone’s invited except for her over there.’ I just wouldn’t be invited to stuff and I’d sit there and be like, ‘It’s okay because I can write a song about this later.’”

This morning Lovato took to Twitter to express her frustration for bullying.

It really surprises me the hateful things people say on the internet.. After all the awareness of cyber-bullying… I mean wow. So sad.

You must have had something really terrible happen to your childhood or you’re really sick in the head. Must suck to be born without a heart
