Izzie haters, be warned!

Katherine Heigl’s not going anywhere yet.

Despite swirling reports that the Emmy winner wants out of Grey’s Anatomy to concentrate on her burgeoning movie career, a rep for Katherine says they’re nothing more than rumors.

“She is starting work next week,” the rep said. “She is returning to Grey’s Anatomy and filming a movie at the same time.”

However, it’s not like the 29-year-old could leave Seattle Grace Hospital even if she wanted to. Katherine still has two years left on her three-year contract and bailing early could result in heavy fines. But an insider reveals that she might be willing to take that chance.

“If it were up to her, she would have her character killed off,” the insider says. “She fears if she waits much longer, the moment will pass [in launching a film career].”

This isn’t the first time Katherine’s caused trouble with her ABC bosses. Early last year, the newlywed dropped out of contract negotiations over a salary dispute, citing disappointment that “Touchstone doesn’t value her as much as her other costars, especially Sandra Oh and Isaiah Washington.”
