'Grey's Anatomy' actor TR Knight has announced that he is gay.
In a statement to People magazine in the US Knight, who plays Dr George O'Malley in the hit series, said: "I guess there have been a few questions about my sexuality, and I'd like to quiet any unnecessary rumours that may be out there."
He continued: "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."
In 'Grey's Anatomy' Knight's character has an unrequited love for lead character Dr Meredith Grey (Ellen Pompeo).
