Shaun Cassidy, All Grown Up
Showbiz runs in Shaun's genes. His parents are stage and film stars Shirley Jones and the late Jack Cassidy. Shaun's older half-brother David broke some hearts of his own as Keith on The Partridge Family.
In 1977, Shaun's song "Da Doo Ron Ron" shot straight to number one. From there, Shaun took the small screen by storm as a handsome teen detective in The Hardy Boys. He also graced every Tiger Beat cover consecutively for almost two years, giving teen girls plenty to dream about.
