Leona Lewis

A striking young woman with a strong vocal resemblance to the young Whitney Houston and a large mop of blonde corkscrew curls, Leona Lewis won the third series of the British reality talent show The X Factor in a landslide. (For non-Brits: The X Factor is the revamped follow-up to the original U.K. talent search, Pop Idol, of which American Idol is the massively successful U.S. version; AI's Simon Cowell is the show's lead judge and executive producer.)
