Fergie

Little do people know that the Black Eyed Peas female vocalist Fergie had somewhat of a career before she stepped on board with the Peas. She was in a little known pop band Wild Orchid, where she developed an addiction to crystal meth and honed her vocal skills. In 2003, Fergie was brought on with the Peas and was responsible for the band's biggest commercial break through. In 2006, Fergie released her first solo album, the ill-named The Dutchess, which brought several radio and dance floor friendly songs.
