Since Katherine Heigl famously left Grey's Anatomy in 2010, there have been rumors that she would someday reprise her role as Dr. Izzie Stevens. But, this doesn't seem likely, according to Shonda Rhimes.

New TV Shows Coming This Fall

A fan tweeted the executive producer and wrote about the ways he or she imagines the character's return. "You better not disappoint me," the fan added.

Yet, Rhimes responded, "I totally won't. Um. Because she's probably not coming back."

Heigl, who starred on the ABC show for five years, previously expressed her desire to return to the series. Her character Izzie had left the Grey Sloan Memorial Hospital to start a new life somewhere else.

“I really, really, really want to see where [Izzie] is. I just want to know what happened to her and where she went and what she’s doing now,” the actress told E! in 2012.

“My idea is that she actually, like, figures it out, and finds some success and does really well in a different hospital. She was always floundering, you know, and so she was always one step behind the eight ball and I want to see that girl take some power back.”

The 35-year-old may not head back to Seattle but she will return to television this fall on NBC's new drama State of Affairs. She will star as CIA agent Charleston Tucker alongside Alfre Woodard (President Roberta Payton).

"We're excited to bring Katherine back to television," NBC Entertainment Chairman Robert Greenblatt said. "This will debut in mid-November and when we saw the first clip of the pilot we knew we had something really special."
