An apology from ‘Grey’s’ actor

“Grey’s Anatomy” star Isaiah Washington, 43, has publicly apologized for his behavior during an on-set scuffle with costar Patrick Dempsey.

“I sincerely regret my actions and the unfortunate use of words during the recent incident on [the] set,” he said in a statement to People magazine. “Both are beneath my own personal standards. ... I have nothing but respect for my co-workers ... and have apologized personally to everyone involved.”

The magazine, citing an on-set source, reported Wednesday on its website that when T.R. Knight was late to film a scene, a debate ensued between Dempsey and Washington, with Dempsey insisting on waiting. The argument intensified, and allegedly a homophobic slur was used, but Knight wasn’t present.

Washington plays Dr. Preston Burke and Dempsey, 40, plays Dr. Derek Shepherd on the ABC drama. Knight, 33, plays an intern, Dr. George O’Malley.

The clash occurred Oct. 9. Knight revealed Oct. 19 that he is gay. “I guess there have been a few questions about my sexuality, and I’d like to quiet any unnecessary rumors that may be out there,” Knight said in a statement. “I hope the fact that I’m gay isn’t the most interesting part of me.”
