Eric Dane joined the cast this season as Dr. Mark Sloane, the cocky plastic surgeon dubbed "McSteamy." He was Derek's best friend until getting caught in bed with Addison. Since joining Seattle Grace's staff, Mark's also had a tryst with Dr. Torres and has tried to seduce Meredith.

Eric says since becoming such a ladies' man on television, his wife, actress Rebecca Gayheart, loves to make fun of him. "I never thought of myself that way," he says. "When I get out of the shower, she's constantly wondering where the guy was that she saw on TV."

Although millions of people watch him on television every week, Eric doesn't count himself among them. "For me, the experience to have is actually making it," he says. "And, you know, you start watching it and then eventually you're going to start looking at things you don't need to be looking at."
