Washington Fired from "Grey's Anatomy"

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 Rhimes 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 on-set troubles, and was a result of a "pattern of problematic behavior."

As for how he feels about his termination, Washington issued the following statement: "I'm mad as hell and I'm not going to take it anymore."

Paging a mediator, STAT!
