Between continued reports of unrest on the "Grey's Anatomy" set, comments made by a fellow cast member and a storyline that has Katherine Heigl's character — Izzie Stevens — riddled with cancer and facing a less than 5% survival rate, fans have pretty much figured that Heigl will not be returning to the show next season.

Not so fast, says the actress.

At a studio party celebrating the series' 100th episode, Heigl says she herself isn't certain of Izzie's fate but that she's game for more if the show's producers are.

"I don't know if I live or die," Heigl tells the AP.

"I was assuming that [I die] at one point and I got a lot of shrugged shoulders and shakes of the head, so I don't know if that's a yes or a no. No one will tell me and I don't know how this is going to go."

Speculation has been that Heigl is ready to leave "Grey's" to pursue a movie career, but the actress is happy with only doing films during her TV hiatuses for now.

"I don't know if I want to continue for five years working 12 months a year, but I can take at least another year of two."

The star of "Knocked Up" and "27 Dresses" can next be seen in this summer's romantic comedy "The Ugly Truth."
