Hollywood heartthrob George Clooney’s best friend forever, Rande Gerber, has given a shout out to human rights lawyer Amal Clooney calling her “a great addition to the family.”

Talking about his BFF, Gerber who is also Clooney’s business partner said that the latter has always been a happy person. “I think [Amal] was the right woman for him. It wasn’t timing, it was meeting the right person,” he said about George getting married to Amal.

The best friends met 20 years ago and they have since built neighbouring houses and created their own tequila company Casamigos. They met during a night out drinking at a New York City bar owned by Gerber and then started hanging out together. They were also joined by another close friend producer, Mike Meldman.

The couples, who holiday together, also have adjoining vacation homes on the same estate in Cabo, San Lucas in Mexico. Gerber told that earlier they had planned to build one big house as George was single then. But, his supermodel wife Cindy Crawford came up with the idea of making two houses on the property, as they had two kids.

Gerber added that when both the couples are on vacation in Mexico, it feels like one big party with breakfast at his house, lunch at George’s house and then again dinner at his house. “We're like one big family,” Crawford’s husband dished.

In a lighter vein, he also revealed a small secret saying that once both the friends were celebrating in his house and had passed out after drinking tequila. George had stayed over at their home in the guest room and Cindy mistook the Hollywood star for her husband.

He recollected how all the three had a hearty laugh after the episode. Even Amal laughed at the stories of the best friends’ antics, including the night of heavy drinking and George going home to the wrong house by accident.

The A-list couple celebrated their first wedding anniversary with a low-key dinner at Tower Bar, Sunset Tower Hotel in West Hollywood on Sunday. Eyewitnesses said that the couple had a quiet, romantic meal and celebrated with champagne. They added that both of them were all dressed up for the occasion.
