Singer Christina Aguilera had to be carried out of a London club on Tuesday morning (28NOV06) after a night of heavy partying. Aguilera's former rival Britney Spears has been grabbing headlines recently with her late nights out with Paris Hilton - and now she seems to have followed suit. The 25-year-old was photographed being carried out of London club Kabaret's Prophecy at 5am over a friend's shoulder. Aguilera and her party ran up a bill of $3,800 (GBP1,900) over the course of the evening. A friend of the star came to her defence telling British newspaper the Daily Mirror that Aguilera didn't drink as much as onlookers might think. The source says, "Not only is she very little, but she was quite tired because she's in the middle of her tour."
