Katherine Heigl : She'll stay if 'Grey's' will have her

LOS ANGELES — Katherine Heigl said Friday 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.

"I'm there" if Izzie remains part of "Grey's Anatomy," Heigl said. She called the set "one of my favorite places to be" and said her colleagues are also friends.

Rhimes, who's also an executive producer for the show, called the milestone a "huge accomplishment" and thanked the cast and crew for their efforts.

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."

"I'm more than happy to make that compromise. As my agent likes to say, 'High-class problems,'" Heigl said.
