Sterling Knight
Even though he portrayed a privileged snob on television, Sterling Knight was one of the most affable stars to emerge from the Disney Channel's cavalcade of young entertainers. The Texas native hilariously portrayed a narcissistic yet lovable teen actor on "Sonny with a Chance" (The Disney Channel, 2009- ), a comedy series about a small-town girl whose acting dream comes true after moving to sunny California. Knight also appeared in the do-over comedy "17 Again" (2009), opposite Disney golden boy-turned-movie star, Zac Efron. Apart from the smug, self-absorbed character he played on "Sonny," in real life, Knight's Southern gentleman charm and natural talent affirmed his potential for a successful acting career well into adulthood.
