It looks like Katherine Heigl is finally, officially done with Grey’s Anatomy. That’s what some sources associated with the production are saying.

According to insiders at ABC and Grey’s, Heigl has been asking to leave the series for nearly three years and she is finally getting what she wanted, Shonda Rhimes and ABC execs have agreed to let her out of her contract.

“She’s leaving the show,” one ABC insider said. “She wants to do movies.”

Apparently, things got pretty tense at one point and one staffer at GA said it was “pretty miserable” and “they [the producers] decided to let her leave.”

It is unlikely that Katherine will return to the Grey’s set at all and apparently, the writing staff is trying to figure out  how to handle her departure in the storyline.

As for Katherine’s side of the story, a source from her camp says that the actress was never given a call time to return to work on the show after her family leave ended earlier this month. According to this source, Heigl’s “calls weren’t returned” when she called in asking when to return to Grey’s.
