Heigl said Friday at a studio party to mark the show's 100th episode that her character's fate is in the hands of series creator Shonda Rhimes. She added that she would be glad to stay on the show.
Heigl also says it's premature to think her days as Dr. Izzie Stevens are numbered. On Thursday's episode, Izzie was seen surviving brain surgery, but there had been speculation that Heigl wanted to leave the show to do films full-time.
The "Knocked Up" actress says she's been lucky to have the chance to balance the series with her film career.
