The 48-year-old actor – who has dated a string of beautiful women, including Renee Zellweger, Kelly Preston and Lisa Snowdon – has struggled to find love, and hopes his new romance with Italian TV presenter Elisabetta Canalis will last the distance.
George told Britain’s Daily Mirror newspaper: “I’ve had some absolutely great relationships and some not so great relationships. “I've been in some relationships where I've felt terribly alone. Just because you're with someone it doesn't mean you're incredibly happy and complete.”
George insists ending relationships is no different when you are famous, although the intense scrutiny on his love-life can make things tough.
He explained: “I've had some easy and natural, made-sense break-ups as well as some rough ones. I deal with them the same way we all do: I'm successful with some and not so successful with others.
"I don't think my experiences are any different than anybody else's, they've just been amplified a little more.” George also revealed he is content with his appearance, and has no problem with his greying hair and lined face - although in his mind he still looks like he did in his heyday.
He said: “I'm old. I'm kind of comfortable with getting older because it's better than the other option, which is being dead. So I'll take getting older.
"It's an interesting thing to be able to watch yourself grow older on screen. I was watching Up in the Air and I thought, 'Jesus, who's the old, grey-haired guy?' And it was me. "I never wear make-up for movies and now it's starting to show.”
