Nothing gets the ladies talking like a hot, single guy on a popular TV show. But what are the actors who play them actually like in real life?

In an effort to answer that, iVillage.com profiled 10 of TV's most eligible bachelors to find out how their characters stack up in the dating world... especially compared to themselves. One of the characters profiled was none other than Dr. Alex Karev of Grey's Anatomy.

It may surprise you to learn that the macho intern played by Justin Chambers bears little resemblance to the actor. Chambers, 35, has been married to wife Keisha for more than 12 years and has five children.

Even in his single days, Chambers says he was "a little more secure with himself. [Alex] is a little more insecure, and hides it with bravado."

Very interesting stuff, and proof that Chambers is a talented actor. He sure makes a convincing insecure jackass on TV! Other TV bachelors profiled on the site were James Denton, who plays plumber/vigilante Mike Delfino on the popular Grey's Anatomy lead-in, Desperate Housewives, and Barry Watson of What About Brian. Both are also married. Sorry, ladies.
