McSteamy is staying put.

Eric Dane, who made his return to Grey's Anatomy in the waning moments of last Thursday's episode, has joined the cast of the hit medical drama as a regular, MSNBC confirms.

Dane plays plastic surgeon Dr. Mark Sloan, a.k.a. "McSteamy," a role he originated in a guest appearance last season, stole the show last week, and is already a fan favorite in spite of his limited exposure.

Grey's Anatomy marks Dane's second co-starring stint as a hot young doctor on an ABC medical drama. Several years ago, he played Dr. Wyatt Cooper on the network's Gideon's Crossing.

Suffice it to say, we're glad he's sticking around Seattle and are eager to find out what happens between Mark and Addison Shepherd (above).
