Looks like Britney isn't the only pop star letting loose these days. Christina Aguilera was caught looking like she drank a little too much the other night. She was spotted being carried out via piggy back of the Kaberet Prophecy Club in London at 5 am. This kind guy tried to cover her head from view of the paparazzi, but if you look closely at all of the pics you can spot those red nails. There's also no denying that platinum hair and gorgeous ring. We hope she wasn't too hung over for her concert at Wembley.
