Hilary Duff

An appealing blonde actress and singer known for her spunk and well-endowed figure, Duff was only 14 when she came to prominence on the hit Disney sitcom Lizzie McGuire, which spawned a feature film in 2003. She solidified her teen-icon status with roles in a succession of popular family-oriented movies (Cheaper by the Dozen, A Cinderella Story) and a series of successful pop albums and tours, including 2005's Most Wanted, a compilation of remixed hits and a handful of new songs cowritten by her boyfriend, Good Charlotte frontman Joel Madden. A fashion plate and tabloid magnet, Duff's personal life was often the subject of gossip, including rumors of a long-running feud with Lindsay Lohan over their mutual ex, Aaron Carter.
