Christina Aguilera celebrated Jordan's b-day in sweats leaving a party at a friend's yesterday. People have been talking about her weekend out in Vegas, but judging from that smile it's not getting under her skin. She told Access Hollywood, "I spend all day with my son and once in a while if I want to go out and have a mommy-daddy night with my husband, I am more than allowed to do that...They never air (footage) of the paparazzi actually pulling up beside my husband and being like, ‘When is she going to leave the house? I have been trying to get a picture of her for weeks.'" That's not the only controversy surrounding Xtina, people are all in a huff over her Rock the Vote ad in which her baby Max is swaddled in an American flag. These may be her mommy rather than drrrty days, but Xtina still knows how to keep people talking.
