After performing at Justin Timberlake’s charity concert at the Theater for the Performing aarts in Las Vegas, newly single Christina Aguilera took her crew of dancers and close friends to Tao nightclub.

Aguilera wore a skintight dress and waved to the crowd from her skybox as the deejay gave her a shout-out, announcing that the “sexiest lady in the world is in the house.” The crowd also snapped pictures of Aguilera, who stayed out until almost 3 a.m.

Other performers included Sir Elton John, Diddy and Dirty Money, Salt-n-Pepa, T-Pain, Lady Antebellum, Selena Gomez and Free Sol at Planet Hollywood.
