Katie Cassidy

Although one would assume it would be difficult to be taken seriously as an actress when your father is a former teen heartthrob, Katie Cassidy made her mark in Hollywood with a solid acting resume both in television and film. Daughter of "The Partridge Family" (ABC, 1970-74) star David Cassidy, the actress captured viewers' attention as a scheming teen in a recurring role on "7th Heaven" (WB, 1996-2006; The CW, 2006-07) and a feisty demon who fought alongside the good guys in "Supernatural" (WB, 2005-06; CW, 2006- ). Cassidy was equally captivating on the big screen, with nail-biting appearances in slasher fests such as "Black Christmas" (2006) and "When a Stranger Calls" (2006). But it was her provocative and alluring role as resident party girl Ella Sims on "Melrose Place" (CW, 2009-10), a remake of the 1990s Fox drama about a group of backstabbing twenty-somethings who live in the same apartment complex, that successfully removed her out from under the long shadow cast by the Cassidy family, thrusting her firmly into her own spotlight.
