George Clooney, Rande Gerber Sell Casamigos for $1 BILLION!!!

Exclusive Details

George Clooney doesn't need your Target gift card for diapers and strollers, because he and Tequila partner Rande Gerber just scored a billion bucks by selling their Casamigos brand.

The buyer -- Diageo, a British alcohol beverage company.

George and Rande agreed to stay with the company, which means they'll rake in even more.

The 2 bros, along with Michael Meldman, created the brand just 4 years ago ... so their return is spectacular.

Rande tells TMZ he's shocked at how much money they made, saying, "We never could have imagined it."
