Casamigos Tequila took over the The Sunset Strip last night with their famous Halloween party. George Clooney, Rande Gerber and Mike Meldman’s highly-coveted event completely transformed an iconic venue into a ‘70s discotheque with all of Hollywood coming out to celebrate. Amal Clooney, DeAndre Jordan, Kim Kardashian West, Courtney Love, Russell Simmons, Alessandra Ambrosio, Joanna Krupa, Seth MacFarlane, Jon Hamm, Adam Levine, David Spade, Isla Fisher, Sacha Baron Cohen, R5, Molly Sims, Zedd, Adrien Brody, Derek Hough, Jessica Lowndes, Shannen Doherty, Harry and Delilah Hamlin, Charlotte McKinney, Rachel Roy, Michelle Trachtenberg, Rachel Zoe and more were hit with the disco fever! Casamigos was flowing and specialty cocktails such as the Bangin’ Margarita, Spicy Mama and Midnight Groove were served over a custom 72-foot diamond mirrored bar. The chrome back bars were lined with endless bottles of Casamigos Tequila intertwined with blue and silver lava lamps. DJ Cassidy kept guests grooving as he spun the best of the ‘70s. Later in the night, Adam Levine and Maroon 5 jumped onstage for a surprise performance.
