In Friday (Sept. 3) night's Disney Channel movie, "Camp Rock 2: The Final Jam," Demi Lovato's character, Mitchie, lets out her inner Mean Girl, gets a little nasty and starts telling people what to do.

This, Lovato says, can by the first step towards a bigger problem -- bullying -- and she wants to get the word out to help stop it.

"We have kids killing themselves over bullies," Lovato tells Zap2it. "I know what it was like to be bullied, and to be that low."
