Grey's Anatomy star Isaiah Washington is at risk of losing out on a pay rise after his homophobic outburst earlier this year.

Washington shocked Golden Globe Award attendees in January by calling gay co-star T.R. Knight a homophobic slur - and the episode is likely to cost the star a wage boost, according to Page Six.

A source says, "All the actors are in the midst of contract renegotiations, but ABC is using Isaiah's recent troubles to keep from paying him more. Isaiah knows it is his fault that he may not get the fat raise he was going to get. ABC doesn't have to give him anything - he is under contract for seven years - and this is going to cost him millions. It's just a bitter pill he is going to have to swallow."

A representative for Washington says, "We are going to do our business in private, not in the press."

Last week, details of a salary dispute between ABC bosses and Grey's Anatomy star Katherine Heigl were leaked to the press.
