Though she got her start on Cosby and Hangin' with Mr. Cooper, Symoné came to real prominence in the Disney series That's So Raven, which ran from 2003 to '07 and spawned a line of DVDs, dolls and merchandise. She was also part of the Disney singing troupe the Cheetah Girls, providing a template for the teen stars to follow.
