Some sites are calling it a "Collapse" one said "Fell asleep" one said "faint."
Our guess : tits up drunk off her ass. Expect a lot of folks to be saying "I told you so" in the weeks to come.
Here is the information from VegasPop:
She had been seated on a VIP tented-cabana bed overlooking the dance floor at 12:50AM talking with one of her male dancers. She intimated she wanted to leave and as she stood up, "she went into a dead faint and just fell right to the floor."Way to go, mom.
Her group pulled her up and lay her on the bed at the same time as her personal security asked for the club to provide at least 10 other security managers to "get her out as quickly as possible." They surrounded the stricken pop star in an attempt to screen her from all observers and the new years revelers on the crowded dance floor.
One woman in the Spears' entourage yelled, "Make sure nobody gets any photos. No photos anywhere."
When the 12-strong security phalanx was in place, two of her dancers wrapped Britney in what appeared to be a blanket-hooded poncho. Literally carrying her in both arms, they managed to propell her through the crowds and out of the club.
It appeared as if "she was being dragged as she wasn't walking under her own speed" said one eyewitness. "It looked as if they wanted to get her up to her hotel room as soon as possible."
At 2AM this morning, an ambulance was summoned to the hotel but it was totally unclear if it was brought to Caesars for Britney.
Good thing she had her entourage there to help her out. If it were an average person, they'd probably just get alcohol poisoning and puke all over the cabana bed.
I like how the article points out that an "ambulance was summoned" to try to indirectly make a connection with Britney. We're talking about Caesars Palace in Vegas on New Years Eve. I'd be surprised if there wasn't an ambulance there.
What happens in Vegas, gets plastered over the rags the next morning.
