George Clooney and Rande Gerber treated their employees to an "epic four-day trip" to Mexico.

The pair and their Casamigos Tequila business partner Mike Meldman splashed out on the lavish holiday to show their appreciation for their staff.

A source told the New York Post's Page Six: "The trip consisted of day parties, tequila lunches, a few daytime meetings, jet-skiing, beach dodgeball, volleyball, beautiful dinners, night parties, glow-in-the-dark golf and fireworks."

George couldn't make it on the getaway as he is currently directing the movie 'Suburbicon' starring Matt Damon and Rande's wife Cindy was also too busy to attend.

However, she sent a cheeky message to her husband, which read: "Babe, have a great trip! Remember - you're there to sell lots of Casamigos, not drink it!"

Rande previously claimed he and George were "forced" into starting a company because they were ordering so many bottles of tequila.

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 legit with the situation."

Meanwhile, earlier this year, George and Rande jointly sold their Mexican homes for $100 million.

The pair offloaded their Cabo properties, which they built on adjacent sites, to a Mexican billionaire who was desperate to have the houses.

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.
