It's hard to imagine that a successful singer and actress like Disney's Demi Lovato would ever be unpopular in school, but the young star told Ellen DeGeneres that she was actually bullied in the seventh grade. "I never really understood why [I was being bullied] until looking back," Demi says on Ellen. "I had a different lifestyle." One thing the actress did want was to stop other girls from being harassed like she was. "I want to help with bullying," she says. "Because there are girls who can't just up and home-school and focus on their career."
