Ian Ziering

Biography: Unlike his Beverly Hills, 90210 costars who struggled to stay in the public eye post-cancellation, this affable actor only took occasional roles, seemingly happy to rest on his reputation as a '90s heartthrob. As a teen, Ziering appeared on soaps before rocketing to fame along with the rest of the fresh-faced 90210 cast. During his 10-year tenure as a cocky but kindhearted high schooler on the hit series, he married Playboy Playmate Nikki Schieler and did voice-over work for animated series such as The Mighty Ducks and Batman Beyond. In the '00s, Ziering divorced, popped up on the small screen every once in a while and poked fun at his image with an uproarious cameo as a nasty version of himself in the 2005 actioner Domino. Two years later, he took on his highest-profile project in years when he signed on to the fourth season of Dancing With the Stars, making it to the semifinals with two-time champ Cheryl Burke.
