Robin Williams

Robin Williams wants to confront the gay men who say they have slept with him because he cannot recall that time of his life.

Williams insists he is 100 percent heterosexual, but many gay men seem keen to "out" him, contactmusic.com reported.

He said: "There are many websites that will go, 'Oh, he is gay - I know he is gay.' Even our chef, who is gay, was at a gay ski lodge, and some guy came up to him and said, 'Robin Williams is gay. Oh, I know he is. I know people who have been with him.' They should tell me, because I don't remember."

Williams says he has never had a guy encounter even when he was taking drugs and bisexuality was the rage.
