Katherine Heigl and T.R. Knight not leaving 'Grey's Anatomy'

Are George and Izzie on call or off-duty?

Earlier this week, news broke that Dr. Izzie Stevens (Katherine Heigl) and Dr. George O'Malley (T.R. Knight) would be leaving the hit ABC show "Grey's Anatomy."

But the show's creator Shonda Rhimes wants to set that record straight - STAT! "That was a very interesting rumor ... and it's not true," Rhimes told People magazine Thursday night at the 40th NAACP Image Awards in Los Angeles.

Castmember James Pickens Jr., who plays "the Chief," was quoted as saying the pair were set to leave the show.

Pickens was also at the NAACP awards, and tried to clarify his remarks.

"When the question was posed to me, I was more trying to congratulate Katie and T.R. on whatever they were going to do. But yeah, I don't have any special info about it either way," he said.
