Isaiah Washington, who backstage at the Golden Globes made some sort of bid to set the record straight about what he did or did not call

T.R. Knight during the infamous October on-set fracas, may have only dug himself in deeper - at the very least with another Grey's Anatomy cast mate, Katherine Heigl. Speaking to Access Hollywood after his latest spiel, Washington reiterated, "There is no way I could do anything so vile" as calling another person the F-word. Heigl, though, says Washington's revisiting of the incident - complete with uttering the epithet - hurt Knight, who was also in the press room at the time. "I'm going to be really honest right now. [Isaiah] needs to just not speak in public. Period," the actress tells Access Hollywood in an interview airing Tuesday. "That did not need to be said, I'm not OK with it. Drawing attention to it and saying the word again is just unnecessary."
