Aguilera, 29, had replaced her sexy image with a more mature and sophisticated style following her marriage and after becoming a mum, the Daily Mail reported. But while performing on the finale of the US celebrity dance show, she left little to the imagination writhing around the stage in a skimpy sequinned dress.
Singing her new track 'Show Me How You Burlesque", the singer certainly showed the crowd her sensual moves, as she emerged sitting seductively on stage with back lighting emphasising her voluptuous figure.
As she belted out her song, the singer stroked her body with red lacquered nails before scantily clad dancers joined her on stage. The mum-of-one flicked her platinum blonde hair back, as she pelted out the seductive song, which is taken from her first film, Burlesque.
