Las Vegas- Britney Spears collapsed at Pure Nightclub early New Year’s Day, cutting short her New Year’s Eve appearance at the Caesars Palace megaclub.

Bodyguards whisked her away from Pure’s VIP section to her suite about 1 a.m. and she did not return.

“She’s fine,” said Larry Rudolph, Spears’ manager. “She had been traveling all day. She got real tired. It was a late night for her.”

It was the second time in two weeks that the hard-partying Spears was carried out of a nightclub. She was helped out of Hollywood’s Les Deux about 2 a.m. on Dec. 22.

Spears had just completed a second New Year’s Eve countdown on the terrace of Pure and had returned to her group on the VIP stage.

“She had a little too much to drink,” said a Pure source. “She was assisted out, but she was not carried.”

Spears was seen mixing a rum and pineapple drink with champagne shortly before her stumbling departure.

Rudolph said Spears “wasn’t drinking that much.”
