The no doubt frazzled actor, 56, ate at Craig's restaurant with Cindy Crawford's husband, 55, in West Hollywood this weekend.
The buddies were seen leaving in style—in a classic 1970's Porsche.
Although the two had a blast chatting over dinner, onlookers said on the way home, Gerber had trouble keeping his door closed and Clooney had to pull over on the side of the road so Gerber could try to fix it!
But the minor mishap is nothing compared to taking care of twins.
"George never believed he could feel such tiredness," the insider told RadarOnline.com.
"He's lucky if he gets even a few hours of sleep a night…because the twins are crying nonstop."
The movie star and lawyer Amal shared a romantic PDA smooch in the European country as well, showing that new parenthood hasn't dimmed their love.
But sources have noted that Clooney isn't giving up his boys' nights with his best friend Gerber.
Clooney, Gerber, Amal, and supermodel Crawford have also taken vacations together. Now, with the twins and the Gerbers' children, there will be even more reason for them all have playdates.
