Rest assured, Gizzie fans. Katherine Heigl isn't going anywhere.

Despite swirling reports that the Emmy-winning actress wants to leave the cast of Grey's Anatomy to concentrate on her burgeoning movie career, a rep for Katherine tells OK! Magazine that they're nothing more than rumors.

"She is starting work next week," the rep for Heigl said. "She is returning to Grey's Anatomy and filming a movie at the same time."

It's not like the 29-year-old newlywed could necessarily bolt Seattle Grace Hospital even if she were intent on it. Katherine Heigl still has two years left on her three-year contract and bailing could result in litigation or heavy fines.

Still, rumors have persisted that she wants out.

"If it were up to her, she would have her character killed off," a source quoted by OK! and several other tabloids stated. "She fears if she waits much longer, the moment will pass [in launching a film career]."

Early last year, Heigl dropped out of contract negotiations over a salary dispute, citing disappointment that "Touchstone doesn't value her as much as her Grey's Anatomy costars," though she eventually re-signed.

Here's hoping that Katherine Heigl and the rest of the Grey's Anatomy cast remain intact and under contract for many seasons to come.
