Are Katherine Heigl and T.R. Knight checking out of Seattle Grace Hospital?

Nay, according to Grey’s Anatomy creator/executive producer Shonda Rhimes.

In an interview earlier this week, James Pickens Jr., who plays Chief of Surgery Dr. Richard Webber on the ABC medical drama, indictated that the stars would be exiting the show. Rhimes says, contrary to the report, T.R. and Katherine are not leaving the show.

“That was a very interesting rumor. And it’s not true,” she told the press at Thursday’s NAACP Image Awards. “You know I don’t like to tell you what’s going to happen on the show, but that is a rumor.”
