Christina Aguilera prefers working late night

London: Pop singer Christina Aguilera has admitted that she is nocturnal and prefers working late at night."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 Aguilera as saying. "But I am still naturally a night owl. I love to work between 3-4 am" she added. These days Aguilera finds it difficult to follow this regime, thanks to her 21-month-old son Max. "Now I am a mother. I am getting up early. It is 6 am every day and even though I am a night owl, now I have to go to bed by 12.30 am All thanks to my son, who has forced me to change my sleeping pattern," explained Aguilera. IANS
