Hilary Duff became a household after starring in the hit Disney series Lizzie McGuire in 2000. At the age of 13, Hilary started dating singer Aaron Carter, prompting a feud with fellow teen star Lindsay Lohan. This didn't slow Hilary down one bit. She started a successful singing career, a tween clothing line, created her own fragrance and although she parted ways with Disney, she starred in films like A Cinderella Story and Material Girls. After a two year romance with Joel Madden, Hilary tied the knot with hockey player Mike Comrie and as of late, the two announced they're expecting their first child!
