Ke$ha looks so demure at the 2013 Billboard Music Awards — until you catch a glimpse of her from the side.
The 26-year-old barely had her backside under wraps in a bottom-skimming LBD with waist-high slits.
The cheeky star looked a picture of sophistication from the front in the high-necked ruffled dress — with not even a hint of cleavage.
But as she turned to the left the singer revealed that she hadn’t totally ditched her naughty side with a huge piece of skirt cut out.
