Cassidy, a 1970s teen idol, eldest son of actress Shirley Jones and a half brother to David Cassidy, is currently the creator and executive producer of "Inseparable," a TV pilot centered on a partially paralyzed forensic psychiatrist with a split personality.
The pilot is in post-production and there is no time frame for its release.
Cassidy, now 50, is married to producer Tracey Turner, and they have two sons, Caleb and Roan. Cassidy has been married twice previously, and he is the stepfather of Jessica Wilson Cruz, and father of Caitlin, Jake, and Juliet Cassidy.
Cassidy's first album in 1977 spawned a No. 1 single, "Da Doo Ron Ron." From 1977-1980, Cassidy released six albums and was a frequent cover boy for teen magazines like "16" and "Tiger Beat."
Cassidy used his family roots, boyish good looks and singing success to enter the television industry, starring in "The Hardy Boys/Nancy Drew Mysteries."
Cassidy eventually got behind the camera, creating TV shows like "American Gothic," "Roar," "Cold Case," "The Agency" and "Invasion."
Somewhat recently, Cassidy starred with his half-brother David in the Broadway production of "Blood Brothers."
