An appealing actress and singer known for her spunk, 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 then-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. The gossip about her romantic life has died down with the announcement of her engagement to hockey player Mike Comrie n February 2010. When not working, she's been a supporter and ambassador for Blessings in a Backpack, which provides healthy food for needy kids to take home to their families for the weekend.
