TMZ has confirmed that Isaiah Washington has been fired from the ABC hit "Grey's Anatomy." Washington's rep Howard Bragman confirmed this evening to TMZ that "Grey's" creator Shonda Rimes called Isaiah today and told him he would not be invited back to the show next season. TV Guide's Michael Ausiello, who first broke the story, reports that the decision was due only in part to Washington's onset troubles and was a result of a "pattern of problematic behavior." http://video.tmz.com/2007/06/07/washington-fired-from-greys-anatomy/ WOW! I thought that was going to be the case. Doesn't sound like he is going to go down without a fight. Between this and her movie Knocked Up coming out at #1 it looks like Katherine Hiegl has more bargaining power for her contract negotiations.
