With the holiday weekend nearly upon us, Mr. Skin would like to wish you a very happy Labor Day. Or as we call it at Skin Central: Labia Day. Start the celebration early with our list of the Top 10 Working Girls; i.e., the hottest celebrities who have played hookers on the big screen. Ladies of the evening like Susan Sarandon, Jennifer Connelly, and Jamie Lee Curtis are sure to have you working stiff!
