Demi Lovato reportedly refused to accept a Barbie doll from a Brazilian fan at her concert this week because she reportedly doesn't agree with what Barbie stands for. According to Starpulse, a fan threw a Barbie doll on stage. Demi reportedly stopped the performance and threw it back to the audience. She said, "I spent my whole life trying to be this and trying to look like this. And guess what? I'm not this... I've been through so much in my 20 years of life. I know how you guys feel and I want to show you guys that you can get through it because I'm living proof right here."
