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 "f*gg*t" - and the episode is likely to cost the star a wage boost, according to PageSix.com. A source says, "All the actors are in the midst of contract renegotiations, but 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.

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 bosses and Grey's Anatomy star Katherine Heigl were leaked to the press.
