Halloween started early with the annual Casamigos Tequila bash taking place in LA on Friday night. George Clooney, who is part owner of the liquor brand along with Rande Gerber and Mike Meldman, wasn't on hand for the event since he was overseas to celebrate a second wedding reception with his bride, Amal Alamuddin. Rande acted as host with wife Cindy Crawford, welcoming plenty of A-list guests in costume. Paris Hilton continued her sexy costume trend with a skin-baring take on Minnie Mouse, while Kate Hudson went with a Dia de los Muertos look, and pregnant Molly Sims was in all pink. Hilary Duff arrived with her estranged husband, Mike Comrie, and Chord Overstreet suited up in a police uniform.
