Christina Aguilera Hot: Singer Wows Onstage In Tight Skirt And A Bra

Christina Aguilera keeps blowing our minds with her new slim, sexy figure.

The singer took the stage Tuesday night during the "Voice" finale to perform "Feel This Moment" with Pitbull, and showed everyone not only how music is done but how amazing she looks now that she lost 20 pounds.

Aguilera, 32, wowed in a skintight black skirt and a bright pink bra with a sheer metallic crop top over it. To make her legs even leaner and meaner, she chose seriously high heeled black pumps.

The stunning mother of one will return to "The Voice" for Season 5, as coach for a jaw-dropping $17 million.
