Britney Spears closed out her four-year Las Vegas residency tonight with a New Year’s Eve performance of “Work B*tch†and “Poison†broadcast live from the Axis Theater on the Vegas Strip. Dressed in a sparkling two-piece outfit and thigh-high boots, Brit danced her way through the first sassy (though likely lip-synced) number, and luckily there was not a nip-slip to be seen this time. You can tune into the rest of ABC’s livestream of Dick Clark’s New Year’s Rockin’ Eve With Ryan Seacrest here.
