Christina Aguilera reportedly spent a hot time in the old town with Enrique Iglesias at a post-concert party for Wednesday's taping of VH1's "Men Strike Back." The New York Post says the two started out dirty dancing on the floor of Nell's, a Manhattan hot spot, then heated up the place even more during a lip-lock session. A representative for Aguilera confirmed that the couple danced, but said, "I do know they didn't go home together."
