George Clooney has given up "kissing girls" on screen due to his advancing years

He told the Daily Mail newspaper's Richard Eden: "I've been trying to go the route Paul Newman did: 'OK, well, I'm not kissing a girl any more'."

Clooney added: "When I turned 60, I had a conversation with my wife. I said: 'Look, I can still play basketball with the boys. I play with 25-year-old guys'.

"I can still hang, I'm in shape. But in 25 years, I'm 85 years old. It doesn't matter how many granola bars you eat, that's a real number."

The former E.R. previously admitted he was left horrified after a director criticised his on-screen kissing skills.

He told the New York Times: "I remember early on in my career, I had to do a kissing scene with this girl and the director goes: 'Not like that.'

"And I was like: 'Dude, that's my move! That's what I do in real life'."

Earlier this year, Clooney revealed he's no longer in a "rush to succeed" because he's already "had [his] career in many ways" and he's now happy to put his family before his own interests and ambitions in the movie business.

The Hollywood star told Extra: "I'm not in that mass rush to succeed anymore. "I've had my career in many ways and you know things were winding down in a way, so I get to be home with my kids a lot and it's fun. I'm still young enough that I can run around with them. That's going away quickly, but I can still do it right now."

The couple recently celebrated their 11th wedding anniversary, and the actor revealed how they marked the occasion.

He shared: "We had a nice dinner night before last."

Asked what the next 11 years will look like for the couple, George replied: "Mostly be me gumming bread because I'm 64, so I'll be 75." Prior to that, George claimed that he's been the "recipient of a lot of luck" in his life.

He told AARP: "I think the only life lesson is to bet on yourself. And when there's opportunities, you gotta go. "In my life, I have been the recipient of a lot of luck. But I also believe you create opportunity for luck. You create enough opportunity and, every once in a while, you'll hit one."
