“Katherine has received a formal pick-up notice and is still hopeful that ABC will show her the same respect that they have shown for her co-stars,” says her rep.
This quote makes it sound to me like she’s not sure she’s going to take them up on their offer. With the runaway success of her latest film, Knocked Up, and the cliff-hanger between Izzie and George at the end of season three, she doesn’t necessarily need them as much as they need her these days. Most of her co-stars have been signed for around $200K an episode plus a share of the show’s profits. Heigl was initially offered considerably less, and that’s why she left the negotiations, and my guess is that if ABC doesn’t step up to the plate, Katherine’s going to walk away again.
