Despite a report picked up on several celebrity news sites, T.R. Knight is not leaving Grey's Anatomy, a show rep told Us Weekly exclusively Monday.

“T.R. Knight has never walked off set in the middle of filming. He attended the table read today and will be shooting this week, just like any other week of production," the Grey's Anatomy rep said, responding to recent reports.

Rumors first erupted after an entertainment lawyer posted on his personal website, CrazyDaysAndNights.net, that Knight walked off and quit the show.

"So, I got a little more information from my source and they say, 'He hasn’t attended table reads since Episode 2. He's pissed and miserable and thinks his story line is stupid,'" he blogged.

"He said goodbye to his hair and makeup people last week. He says he is done and has quit. ABC has not released him. Shonda Rhimes, the producer called him and he told her he had nothing to say. He has packed his dressing room.”

Although it has now been emphatically denied, it's interesting that this rumor popped up after T.R.'s character, George O'Malley, has been conspicuously MIA for weeks. One wonders if there may be a little truth to it, even if the incident were exaggerated. Thoughts?
