Child Actors Turned Singers: Fergie

Before Stacy Ferguson became so famous she could go by only one name -- Fergie -- she logged five years on the music-themed show 'Kids Incorporated' and several more years as part of the girl-group Wild Orchid.

You know the rest -- she later joined the Black Eyed Peas and had successful solo hits like 'Girls Don't Cry.' She's also spoken very candidly about her prior substance abuse problems, something she's said was the fallout from learning to "suppress feelings" as a child actor.
