DR. McSTEAMY SIZZLES UP "GREY'S ANATOMY"

Eric Dane is back on "Grey's Anatomy" as McDreamy's nemesis Dr. Mark "McSteamy" Sloan and the fans across the country have cheered in approval. That's after their jaws dropped in shock.

In a sizzling closing scene of this week's episode, Dr. Derek "McDreamy" Shepherd (Patrick Dempsey) makes a decision to break up with his estranged wife Addison (Kate Walsh) for good and visits her to deliver the news. It appears however she has already moved on as McDreamy's former best friend and Addison's not-so-former lover McSteamy walks out of the bathroom wearing nothing but a towel.

Eric Dane will now be joining the cast of "Grey's Anatomy" as a series regular.
