"George and I met probably over 20 years ago," Gerber shared with ET. "He was shooting a movie in New York. I owned a bar at the time and he was coming in and we just became friends. We'd have a couple of drinks, couple of tequilas. Actually we met over tequila."
Meeting over tequila is meaningful, as they now own their own tequila company -- Casamigos. The drink debuted on the U.S. market in 2013, but started out as a private passion project between Clooney and Gerber. The two friends were on a mission to create the perfect tequila -- and after two years developing it and then two additional years drinking it, they were informed they had been ordering 1,000 bottles of Casamigos a year.
According to Gerber, he and Clooney were told they had to get licensed and "get legit" in order to keep producing the tequila.
