The usually buttoned-up pair had a fun night out in London on Saturday, joining famous friends at Electric Cinema and Club in the Notting Hill neighborhood. An eyewitness told ET that the pair were "very touchy-feely" and "seemed very much in love."

According to an eyewitness, Amal had "a couple" drinks over the course of the night and when the group made their way to their cars at evening's end, the human rights lawyer -- who was "extremely loud and chatty" and "appeared to be tipsy" -- showed off a little more than she bargained for, accidentally flashing the paparazzi as she climbed into the car!

The couple were joined by pals Matt Damon and his wife, Luciana Barroso, as well as Clooney's business partner, Rande Gerber, and his wife, Cindy Crawford, for dinner and drinks, and ET's eyewitness said that "spirits were high" as the group enjoyed themselves on the three-hour triple date.

Clooney and Gerber are in London celebrating the U.K. launch of their Casamigos Tequila brand, as well as the release of Crawford's new book, Becoming.

According to the eyewitness, the fun continued all the way to the valet stand, as Amal and George hopped into Damon's car by accident, provoking "hysterical" laughter from the group.
