Child Actors Turned Singers: Demi Lovato
At only 19, Demi Lovato already has a long showbiz resume, including an early stint on 'Barney & Friends' and later work in the 'Camp Rock' movies and on the Disney Channel sitcom 'Sonny with a Chance.'
She's since released three successful albums, but personal troubles have followed along the way. Now, like beleaguered fellow star Britney Spears, she's reinventing herself with a judging spot on 'X Factor' (although we're starting to think Simon Cowell is some sort of father to wayward starlets).
