Before John co-starred as tall, dark and handsome Uncle Jesse on "Full House," he made fans swoon as Blackie Parrish on the daytime soap "General Hospital" (he also had a brief stint on "Dreams"). Since then, the actor has shown off his good looks on small-screen hits like "ER" and "Glee." Since finalizing his divorce from Rebecca Romijn, John has been enjoying the single life and living out his longtime dream of touring as a drummer with the Beach Boys.
