Katherine Heigl said she's ready to stay with “Grey's Anatomy” and the decision rests with the show. Attending a studio party to mark the ABC medical drama's 100th episode, Heigl said it's premature to think her days as Dr. Izzie Stevens are numbered. “I was assuming that 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,” Heigl said, noting series creator Shonda Rhimes' passion for plot secrecy. “I don't know if I live or die. I don't know how Izzie fares,” said the actress, who's played the character since the show debuted in 2005. She called the set “one of my favorite places to be” and said her colleagues are also friends. She and fellow cast members, including Ellen Pompeo (Dr. Meredith Grey) and Patrick Dempsey (Dr. Derek Shepherd), were on hand for the celebration that included a cake decorated with scalpels and syringes made out of icing. Last month, fellow cast member James Pickens Jr. said Heigl was leaving the show, along with T.R. Knight, both of whom declined comment at the time. On Friday, Heigl said she's comfortable balancing movies and TV by working on big-screen projects during the summer hiatus for “Grey's Anatomy.”
