Christina Aguilera was again spotted at a New York strip joint according to the New York Post. This time Aguilera was even dirtier when the club’s DJ played her single ‘Dirrty’. The singer jumped on a couch in the Champagne Room and started bumping and grinding with two strippers. Later, she compared breasts with one particularly well-endowed dancer. “They were touching each other’s breasts,” said one elated eyewitness. “There was a lot of caressing going on.” Her back-up dancers joined in on the fun, performing an impromptu striptease on the main stage.
