Katherine Heigl looking to hang up her ‘Grey’s’ scrubs?

Fifteen months ago, Heigl renegotiated her “Grey’s” contract. The net result from that: Because the negotiations went public and she got the raise she wanted from the show, Heigl proved she wasn’t about to become an of-the-moment primetime star. Additionally, Heigl has had tremendous big-screen success with her leading roles in “Knocked Up” and “27 Dresses.”

“She’s a smart one. She saw what can happen with someone like Jennifer Aniston, who was crazy successful on TV, but can’t seem to carry a film, and she tested the waters early,” said a movie industry source.

Even so, Heigl might be locked into “Grey’s” a bit longer. “I don’t think she’ll be able to get out of it,” the US source said of Heigl’s contract.
