Diagnosis Payback: Katherine Heigl's loses war with Grey's Anatomy producers!
In a stunning about-face, she's now begging producers of the hit ABC drama NOT to kill her off - just months after she threatened to walk, sources say.
The 30-year-old beauty had hinted that she wanted to concentrate on her film career after the one-two box office punch of her hit comedies Knocked Up and 27 Dresses.
"But with the economy tanking and a key role in a huge TV hit, Katherine's not ready to quit her day job," an insider told The ENQUIRER.
"Now she's groveling with the producers, trying to convince them not to kill off her character. She'd like a few more lucrative seasons on Grey's while she continues to build a reputation in the film world."
The actress ignited a firestorm last summer when she pulled herself out of the running for an Emmy nomination, claiming the show's writers hadn't given her material that was good enough to warrant recognition.
The insult didn't sit well with Grey's creator Shonda Rhimes or the show's writing team.
Soon after, Katherine's character Dr. Izzie Stevens was diagnosed with advanced brain and liver cancer - hinting imminent kill-off .
But now producers are keeping Izzie's fate up in the air.
Katherine recently told a reporter: "I don't know if I live or die."
The source added: "The producers are messing with Katherine now. They won't give her a concrete answer. She's learned …just how cutthroat this industry can be."
