Grey’s Anatomy has enlisted former 24 and Lipstick Jungle actress Kim Raver to throw a wrench into Owen and Cristina’s burgeoning romance, according to reports.

Kim will be joining the hit medical drama in its sixth season as a new SGH surgeon as well as a possible love interest for Kevin McKidd’s character, Dr. Owen Hunt.

This coincides with the Grey's Anatomy spoilers we've read that someone from Owen's past may appear to reveal that the hot trauma doc's closet has skeletons.

“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 a recent interview.

“I think it could get a little tricky, to say the least, but also exciting and interesting," he added. "Hopefully it will bring [Owen and Cristina] closer in the long run.”

Raver’s role is recurring and she will debut on November 12. In addition, EW reports this morning that Katherine Heigl (Izzie) will begin her string of five non-consecutive missed episodes following a traumatic event in next week's episode.

Meanwhile, Ellen Pompeo's Meredith is not going to miss any episodes due to her maternity leave, however we will see less of her beginning next week as well.

There will apparently be a plot line to explain this as well.

Who do you think Kim Raver is playing and now does she know Owen? Are you excited for the new blood on Grey's this year or do you just miss the old days?
