Britney Spears Makes Vegas Return For Holidays After Wemby Slap

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.

The source tells us she was at The Wynn to watch the show "Awakening" and dined at their swanky seafood restaurant, Lakeside.

Her Vegas schedule was jam-packed -- she also took a tour of the brand-new Fontainebleau property, briefly checked out LIV, and spent time inside their members-only club, Poodle Room.

Basically, we're told her time in Vegas was super chill and inconspicuous -- nothing like last time when she was slapped by basketball player Victor's security when she beelined behind him after running into him in a hallway.

Video of the moment went viral ... and upon watching it, Britney said her reaction to the slap was "priceless."
