Under wraps! The pregnant barrister Amal Clooney somehow found time to throw a birthday party for her husband George at their home in London — and keep it a secret. Clooney tapped best friends Rande Gerber and Cindy Crawford for help, a source tells E! News. “Amal set it all up, and Rande and Cindy surprised George when he got home Saturday,” a source explains. When George pulled into his driveway, Rande “came from around the bushes driving George’s lawnmower and pulled up beside George’s car while Cindy was nearby in the garden cutting fresh flowers. George was totally surprised!” George and Rande launched Casamigos Tequila together in 2013 and Amal had a cake made that replicated a bar from their home in Mexico. Rande shared a shot of the amazing cake on Instagram. George turned 56 this year. Have you ever thrown a surprise party?
