George Clooney "doesn't give a s**t" if people think he is gay.

The 'Descendants' star - who is currently dating ex-wrestler Stacy Keibler - is "very happy" with his private life and laughs it off when people say he's homosexual, but he would never get angry about the rumours for fear of giving an impression that there's something wrong with being gay.

He said: "I think it's funny, but the last thing you'll ever see me do is jump up and down, saying, 'These are lies!' That would be unfair and unkind to my good friends in the gay community.

"I'm not going to let anyone make it seem like being gay is a bad thing. My private life is private, and I'm very happy in it.

"Who does it hurt if someone thinks I'm gay? I'll be long dead and there will still be people who say I was gay. I don't give a s**t."

The 50-year-old actor believes one day people will be "embarrassed" to have been against marriage equality because it will seem "archaic" in the next generation.

In an interview with The Advocate, he added: "One day the marriage equality fight will look as archaic as George Wallace standing on the University of Alabama steps keeping James Hood from attending college because he was black. People will be embarrassed to have been on the wrong side.

"So it's encouraging to know that this too will seem like such a silly argument to our next generation. There are even a lot of young conservatives today for whom marriage equality isn't an issue. It always takes government an extra generation to catch up to the people."
