The delicious Eric Dane who guested starred last season as Dr. Addison Shepherd's lover - the guy who broke up her marriage to Dr. McDreamy - is joining the cast of "Grey's Anatomy" as a regular cast member. "I'd like to see the relationship between Derek and Mark get repaired," Eric says of his character. "But you gotta think this guy's gonna cause trouble no matter where they put him."
Grey's fans know that Dr. Mark McSteamy Sloan (Eric) was Derek McDreamy Shepherd's best friend until Dr. McDreamy caught Mark in bed with his wife Addison which made McDreamy run away to Seattle to start over. Addison then followed McDreamy to Seattle, landing a job at his hospital, and now McSteamy has shown up too, to continue wooing his best friend's ex-wife.
As with all things on Grey's Anatomy ... this ... is going to get interesting!
