Grey’s Anatomy has enlisted Jack Bauer’s ex and a former Lipstick Jungle star to throw a monkey wrench into Owen and Cristina’s burgeoning romance, Entertainment Weekly reports.

Sources confirm that Grey’s Anatomy has tapped former 24 heroine Kim Raver to join the cast as a new SGH surgeon and a possible love interest for Kevin McKidd’s Dr. Owen Hunt.

Back in August, Kevin McKidd revealed some Grey's Anatomy spoilers, namely that a major skeleton would tumble out of Owen’s closet in this transitional season of Grey's Anatomy.

“Someone comes to the hospital that he was connected to in his past, not his ex-fiancée, but it’s somebody we didn’t expect,” the actor said in an interview with E! Online.

“I think it could get a little tricky, to say the least, but also exciting and interesting."

"Hopefully it will bring [Owen and Cristina] closer in the long run.”

Raver’s role is recurring and she will debut on November 12. Who do you think she's playing, and are you excited? Or are all these new doctors just making the cast too crowded?
