Britney Spears decided she'd give Sin City another shot ... celebrating the holidays there 5 months after enduring a slap from Victor Wembanyama's security in a bizarre exchange.
Sources tell TMZ, the singer returned to Vegas over the holidays ... staying for a few days, though it's unclear if she spent Christmas Day among all the lights and excitement.
We're told Britney had a room at Resorts World and another at Aria. Video emerged on social media of Britney walking around the casino floor at The Wynn holding a beer and flanked by a few security guards.
