Katie Cassidy

Katie Cassidy -- the daughter of onetime Partridge Family sensation and teen idol David Cassidy and fashion model Sherry Williams -- jump-started her fame not as an actress but as a teen pop star, à la Britney Spears or Jessica Simpson. A trained vocalist from the age of 12, Katie teamed up with music mega-producer Joel Diamond in 2004, and released her first single that summer, banking off of her father's fame with a remake of "I Think I Love You." In 2005, Cassidy appeared in a recurring role on the popular family drama 7th Heaven as Zoe. She slid into the feature arena inauspiciously, as Kelli, one of the slasher victims in the grotesque, critically panned gorefest Black Christmas, then traveled the comedic route with supporting roles in the Adam Sandler vehicle Click (2006), the ensemble picture You Are Here (2007, as an aspiring Hollywood climber), and the Cary Elwes comedy Walk the Talk (2007). Cassidy is perhaps best known, however, for her recurring role as Ruby on Supernatural, a program about a couple of young men journeying across the country in their black Impala and fighting off evil supernatural forces. ~ Nathan Southern, All Movie Guide
