Hollywood's 'Good Girls'

If you are talking about goody-two-shoes, there may be nothing sweeter than starting off your career as a child star on one of the most beloved sitcoms ever. Raven Symone did just that when she began working on "The Cosby Show," and she was barely out of diapers. After that, the too-cute kid released a rap single and had a stint on another sitcom before becoming one of the Disney Channel's biggest stars. "That's So Raven" is still in production and she also has a film career. (Noel Vasquez/Getty Images)
