Katherine Heigl has traded in her sun-kissed blonde locks for a really dark shade of brown. She’s gone darker before, in that movie 27 Dresses (which sucked). But this is the darkest I’ve ever seen her hair, and it does not look good. I’m not one of those people who is always like “Blonde is better, lighten your stuff up.” It depends on the person, and I am a very happy brunette, and always have been. But Heigl needs to go back to a lighter color. Because this stuff looks like the Britney Spears “I’m goin’ crazy y’all” Special.

Meanwhile, it’s looking more and more like Grey’s Anatomy producers and writers are totally done with Dame Heigl. Entertainment Weekly’s gossip guy claims that Michael Ausiello’s sources claim that “no one knows” how much longer Heigl will be hanging around, bitching and moaning. Here’s more… but beware, there are SPOILERS about other cast members:

It looks like Grey’s Anatomy will be down two doctors next season, and, believe it or not, neither of them are played by Katherine Heigl!

Sources confirm to me exclusively that Mercy West transplants Robert Baker (Dr. Percy) and Nora Zehetner (Dr. Adamson) are not expected to return next season.

There’s no official word on the fate of fellow “invaders” Jesse Williams (Dr. Avery) and Sarah Drew (Dr. Kepner), but there’s buzz both may stick around long-term. Grey’s boss Shonda Rhimes has until June to decide whether to exercise the series regular options in their contracts. (Here’s hoping she does; I like those two.)

Heigl’s MIA Izzie, meanwhile, will reappear in April. But for how long? Confides an ABC source: “No one knows.”

Thoughts? Will you miss Percy and Adamson? Should Rhimes keep Avery and Kepner around? And are you so over the Heigl drama? I kind of am.

Since Heigl isn’t due to return to Grey’s for a while, I’m thinking the dark hair is for a character, probably for a film. Who knows, though? She probably just pitched a fit to her hairdresser and he was like “I’m gonna show this bitch how nondescript she really is.”
