Demi Lovato

Demi Lovato is one of the sexiest new faces on television with her spot on the judges panel for the US X Factor 2012, but she still has issues about her body.

She recently shared a history of how long the issues have bothered her and admitted her body issues began when she was only three years old.

The 'X Factor' judge - who has spent time in rehab getting treatment for her eating disorder and self harming - admits she felt she was overweight from a very young age, and the insecurities have stayed with her.

She told talk show 'Katie': ''I remember being three years old in a diaper and rubbing my hand over my stomach ... and I remember thinking in my head, 'I wonder if one day this will ever be flat?' ''

The 20-year-old beauty - who has recently been named as the new ambassador of a bullying campaign - was targeted at school as the girls used to tease her for her appearance.

Demi added: ''It played more of a toll on me than if I was physically abused in school. I've always said I wished that they had just hit me in the face and gotten it over with because what they said to me sticks to me to this day and it affected me, (turned) me into the person I am today. I was bullied and they called me fat and they called me horrible things.''
