Our favorite Pop-princess turned train-wreck, Britney Spears collasped last night while hositng a New Year's Eve party at Caesar's Palace hot spot PURE in Sin City. Many are speculating whether it was the champagne or just exhaustion.

I don't know about you, but isn't this the girl with a Red Bull glued to her hand at all times? How can you fall asleep in the middle of a bass-thumping club with that in you system?

I bet she passed out after learning her ex-husband was looking dapper at a party in Miami, where he was partying with some hot chicas!!!

I think Brit's new year's resolution should be to stay home at least five nights out of the week.
