Fans eager to know more about the newest Grey's Anatomy cast member, Eric Dane, can get their wish tomorrow. The Insider has learned that the heart throb will be appearing on The Ellen Show at 11 a.m. Eastern.

The actor, like his character, Dr. Mark Sloan (a.k.a. McSteamy), is still shrouded in mystery. For all the buzz he's created and impact he's had on Grey's Anatomy, Mark has had very little screen time thus far.

We're looking forward to finding out more about him, though we're guessing he won't dish too much about his forthcoming Seattle Grace dealings. Creator Shonda Rhimes is a bit secretive, as we know.

Dane is married to actress Rebecca Gayheart, who fans may remember from Noxzema commercials, a stint on Beverly Hills: 90210 and other roles. We found picture of the couple taken last weekend at the benefit for the Rape Treatment Center of Santa Monica.
