Greatest Hit: "I Wanna Love You Forever" (1999)

Jessica Simpson may be a full-time mom now, but over a decade ago, Simpson hit the scene as a nubile blonde babe with her smash hit "I Wanna Love You Forever." As of today, she's sold 30 million albums worldwide, although her music career hasn't always been her main focus.

Simpson has dabbled in acting, fashion design, and TV—and we're not talking about her reality show Newlyweds with ex-husband Nick Lachey. We'll always remember her for re-popularizing the Daisy Dukes with The Dukes of Hazard remake.
