Christina Aguilera works better late at night but she had to change her patterns for son Max. "When the sun goes down, my whole body starts to come alive, although I am a little different now because I do have a child and my hours have been turned upside down for him," contactmusic.com quoted her, as saying. She adds, "But I am still naturally a night owl. I love to work between 3-4 a.m." "Now I am a mother. I am getting up early. It is 6 a.m. every day and even though I am a night owl, now I have to go to bed by 12.30 a.m. All thanks to my son, who has forced me to change my sleeping pattern."
