Today T. R. Knight, who plays Dr. George O'Malley on ABC's Grey's Anatomy, confirmed to People Magazine that he is gay. Said Knight, “I guess there have been a few questions about my sexuality, and I'd like to quiet any unnecessary rumors that may be out there. While I prefer to keep my personal life private, I hope the fact that I'm gay isn't the most interesting part of me."It shouldn't be, but there is little doubt there will be a great deal of media interest in Knight's coming out. He is, after all, a star of one of ABC's most important shows. Knight doesn't address exactly what led him to come out, but speculation is that it has something to do with the recent fight between Grey regulars Patrick Dempsey and Isaiah Washington. The National Enquirer reported last week that a scuffle broke out on set between Dempsey and Washington when Washington grew annoyed with another cast member's tardiness. During the fight, Washington reportedly said to Dempsey, “ I'm not your little faggot like (name deleted).” That name apparently was Knight's whom reports also have Washington calling a “bitch” at one point earlier during the argument.
