Usher got it bad last night during a headlining performance at Madison Square Garden. The “OMG” singer invited a special lady up on stage while performing “Trading Places,” but things took a turn for the worse when the woman tried to maneuver her legs around the star and accidentally kicked him in the face. Ursh played it off like a champ, getting off the couch and leading his lady off the stage before continuing with the gig. Ouch!
