Daughter of 1970s teen idol David Cassidy and granddaughter of Broadway legend Jack Cassidy, Katie Cassidy was modeling for Abercrombie & Fitch in high school and recorded a cover of her father's song "I Think I Love You" before she made her acting debut in a 2003 episode of the cop drama The Division. Katie then went on to star in two classic slasher-movie remakes, When a Stranger Calls and Black Christmas, in 2006 and landed recurring roles on Supernatural and the whodunit series Harper’s Island. Katie's now a bisexual bad girl on the new Melrose Place, but to see Katie takin' off her clothes, you'll have to check out Live! (2007). Katie's rack flash will make something come alive in your pants. We had to wait seven long years for Katie's next flash of flesh, but it turned out to be her best yet, when she bared her updated boobage in the techno-thriller The Scribbler (2014). That'll make you get your pen out for some doodling!
