David Arquette played Santa to staff at his Los Angeles nightclub, Bootsy Bellows, by flying all 40 of his employees to Las Vegas for the ultimate holiday party. The group got into the spirit at Simon Hammerstein’s The Act at the Palazzo, where we’re told they took over the private VIP area at the performance-based club. Rehabbed Arquette, who our source says stuck to water, also mingled with celebrity stylist Brad Goreski, actress Christian Serratos and Jeannie Mai.
