The “Brought To You By Those Who Drink It” LA party took place in cofounder Mike Meldman’s house and featured plenty of Halloween décor, branded Casamigos bars lined with hundreds of bottles of the tequila, signature cocktails, and food like Kobe cheeseburger sliders, mini hot dogs, tacos and burritos, and vegan ice cream.
Guests like Harry Styles and Paris Hilton were greeted with a Casamigos ice shot, made the most of a slow-motion photo booth and selfie balls, and crowded into Meldman’s sports room to watch the World Series, all while DJ Michelle Pesce played all night.
The scene was just as elaborate on Saturday, when all three Casamigos founders – George Clooney, Rande Gerber, and Mike Meldamn – partied at the newly opened CATCH Las Vegas at ARIA Resort & Casino in a space with black brick walls, neon signs, glitter Casamigos barrels, a custom agave made of mini Casamigos bottles over the main bar, cocktails, and Asian-inspired cuisine like lobster mac and cheese.
Guests like Clooney, Kendall Jenner, and Steve Aoki listened to DJ Cassidy, a performance from Nas, and even a surprise DJ set by Jenner herself.
