Her initial claim to fame was being the older sister of pop singer/actress Hilary Duff, but Houston native Haylie Duff has since come into her own, appearing in the WB show 7th Heaven.
Additionally, Duff may be remembered for her performance in the 2004 cult hit Napoleon Dynamite as Summer Wheatly. Duff starred in the 2006’s romantic comedy Material Girls alongside sis Hilary and lent her voice to the not-yet-released animated flick Foodfight!.
Also a talented vocalist, Duff has contributed songs to the Cinderella Story soundtrack and supplied vocals on the hit single "Our Lips are Sealed."
The actress is currently dating Matt Rose.
