GEORGE CLOONEY’s bride-to-be, 36-year-old British lawyer AMAL ALAMUDDIN, just got her first taste of the braying frat-boy humor he enjoys with male Rat Pack besties MATT DAMON, BEN AFFLECK, RANDE GERBER, BRAD PITT, LEO DICAPRIO, DAVID BECKHAM, BONO, et al. – and damn near GAGGED!
First-responder Brad Pitt sent a note of congrats on the engagement… along with an antique horse collar wrapped around a photo of George in a round acrylic case!
The card read: “To my friend George, who will soon have to wear one of these full time when he gets hitched. Sorry, but I couldn’t find anything for the horse’s other end!”
Said an insider: “Clooney thought the gift was hysterical, but Amal just did NOT see the humor.” (Now that’s a wife!)
