The 'Monuments Men' actor and his best friend - who is married to Cindy Crawford - have offloaded their Cabo properties, which they built on adjacent sites, to a Mexican billionaire who was desperate to have the houses, TMZ reports.

The two abodes were the last properties designed by famed architect Ricardo Legorreta before he died, and Rande and Cindy have previously featured their retreat in prestigious Architectural Digest magazine.

Despite selling up, George - who is married to lawyer Amal Clooney - and Rande won't be without homes in the area for long as they are planning to build an "even more spectacular" compound together.

The two friends also have their own tequila business, Casamigos, and Rande previously claimed they were "forced" into starting a company because they were ordering so many bottles.

He shared: "George and I started drinking tequila a very long time ago. There came a point when George said to me, 'Why don't we just make our own.' We never meant it to be a business.

"We started out just us drinking it, without anyone being able to buy a bottle. We were kind of forced into [making it a business], after about two years, we got a call from our distillery and they said to us, 'We have a situation. For the past two years, we've sent you a thousand bottles a year. Either you're selling it, or you're drinking way too much. You need to get licensed and get legit with the situation."
