The Emmy nominations are out, Katherine Heigl didn't get one, and she's free to say whatever the hell she wants again! The perennially charming actress dropped by Letterman last night to flog her latest movie, The Ugly Truth, but mostly to complain at length about toiling away in the Grey's Anatomy salt mines under the cruel authority of evil creator Shonda Rhimes: "Our first day back was Wednesday and it was — I'm going to keep saying this because I hope it embarrasses them — a 17-hour day, which I think is cruel and mean." (As Letterman points out, this would seemingly indicate that her character's not dead.) Also, asked by Dave how much longer she'll be on the show, she replied, "Yeah, that's what I keep wondering." Look for an episode next season in which doctors put Izzie's brain tumor back in.
