Faye Dunway? Seriously? Dr. McDreamy and Dr. McSteamy will be joined by the big screen legend also known as “Mommie Dearest”. Wow.

Sources confirm to me exclusively that the Oscar winner (for Network), who hasn’t taken a small-screen gig since a 2006 episode of CSI, has signed on for at least one episode of Grey’s Anatomy to air in February. She’ll play a renowned doc at the hospital who crosses paths with the Chief, Cristina and Owen.

Well, that’s definitely one we couldn’t have guessed in a million years, eh?
