Eric Dane happily married to actress Rebecca Gayheart

Grey's Anatomy's Eric Dane has been happily married to actress Rebecca Gayheart for 4 years. The actor, who stars opposite Owen Wilson and Jennifer Aniston in Marley & Me, says he's figured out the secret to wedded bliss, OK reports

"Work. And it's worth it," he tells Parade.com. "I'm 36 and I've found that anything worth having is work. It takes a lot of work to keep your marriage on track but I think it's incredibly rewarding too."

Dane, who says he prefers to think of "McSteamy," his Grey's character, not as a womanizer but as a "careerist who just likes women," says he still has a couple of single friends. But he tends not to understand them as well as he'd like.

"I have a couple of single friends, and their willingness to stay single baffles me," he says. "The issues they have with some of the women they date are so just insignificant to me but so monumental to them. I don't get it."
