American actor and filmmaker George Clooney has revealed the secret to his happily married life with lawyer Amal Clooney née Alamuddin. The Gravity star and 36-year-old British-Lebanese activist, tied the knot in September 2014, in Venice, Italy.

"Facetime – we will do that but mostly it is trying to not go too long without being apart, and you do the best you can. We spend an awful lot of time together. We don't have huge gaps," he said, as quoted by the DailyMirror.

"We are able to manage, so far. Between my work and her work and the things we have been doing, we have been able to manage it pretty well," George added.

Meanwhile, during an appearance on The Ellen DeGeneres Show, George revealed how he proposed her. He said: "I plotted the whole thing out. I had the ring hidden behind her. I had music playing. ...Everything was planned out and I've cooked dinner."

"[Amal] comes in and she's just come back from London. Usually, she'll dress up and now she's like, 'Maybe we'll just order in.' I go, 'No, no, no I've made dinner.' I've got it all set up, timed out and the song is coming and she gets up to go wash the dishes, which she's never done," he explained. "And I'm like, 'What are you doing?' and then she comes back in."

"Finally I said [that] I blew out the candle and I think the lighter's in the box behind you. And she reaches around, pulls out the box and I've got just the ring sitting in there. She pulls it out and she looks at it and she's like, 'It's a ring,' like as if somebody had left it there some other time," he told DeGeneres.

"I'm doing all the moves you can do with my face. I got down on my knee and said, 'I couldn't imagine spending the rest of my life without you.' And she kept looking at the ring and she was looking at me and she was like, 'Oh My God.' And we now know, because there was a playlist [and] we know how long it actually took, it was like 25 minutes."

"Finally, I literally said, 'Look, I hope the answer is yes but I need an answer. I'm 52 and I could throw out my hip pretty soon'," he went on. "And she said, 'Oh, yes.' It worked out really well."
