Hilary Duff and sister Haylie Duff have been battling - and sometimes avoiding - feud rumors for years. The Texas-born siblings grew up in the spotlight side-by-side after moving to Los Angeles with their mom in 1993. Hilary landed her first major role as Wendy in 1998's Casper Meets Wendy, going on to star in Disney Channel's Lizzie McGuire, A Cinderella Story, Cheaper by the Dozen, Younger, How I Met Your Father and more. Simultaneously, she solidified her pop star status in 2002 with her Santa Claus Lane album, followed by 2003's Metamorphosis and three more albums.
