Initially emerging as a star among Disney's army of would-be teen idols, Hilary Duff has followed in the footsteps of divas like Britney Spears and Christina Aguilera, refashioning herself as a pop icon for all ages. Introduced to the masses as the titular star of Lizzie McGuire, Duff released her triple-platinum selling debut in 2003. Alongside her successful film and TV career, she's continued to put out sturdy collections of increasingly mature pop music, relating tales of love and loss to an audience that's followed her since day one.
