The 'Monuments Men' star and the 49-year-old beauty - who is married to Rande Gerber - own adjacent houses in Cabo, Mexico and are reportedly planning to sell one and time-share with the other home.
A source told Entertainment Tonight: ''When George was single and living a wilder lifestyle, having that big house for all his parties made sense.
''But now he's settled down with Amal - those days are behind him.''
And when they do choose to sell, they will have no problem getting a hefty sum for the home as it features no less than seven bedrooms, ten bathrooms, swimming pools and a separate quarter for staff. The mansions also boast 180-degree views of the beautiful surroundings.
Meanwhile, Cindy recently revealed she ''respects'' George and Amal for not bothering to try and keep their wedding a secret.
She said: ''I think George decided - and Amal, too - which I thought was smart of them, typically, that either you spend all this time and energy trying to make it secret or you just go, 'You know what? We're getting married in Venice and we're going to have this great party and we're going to do exactly what we want.'
''So that's what they did and I really respected them for it.''
