Britney Spears's wild weekend

If Britney Spears is trying to class up her act, she sure is doing a bad job. This past weekend she puked in one NYC hotspot (Tenjune) and then, only hours later, cavorted around in a bikini in another (ONE). And it wasn't just any bikini, Spears borrowed one from a go-go dancer who was entertaining at the club that night.

It started out Saturday night (or really quite early on Sunday morning). A source for Star magazine said, "[Britney] got there [Tenjune] around 12:15 a.m., was drinking champagne, dancing and hanging out with friends. And around 3:15 a.m. and took her new CD out of her bag, got on the microphone and just said 'Hey, guys, it's Britney!' The crowds reaction to her new songs was positive!"

Spears must have been super excited about the reception her new songs was getting because she was certainly celebrating. In fact, Britney partied so hard that she was seen leaving her limo that night with stains on her jeans (according to the New York Daily News), presumably a result of throwing up. There was also vomit visible in the seat of the vehicle and Page Six claims that Britney barfed in Tenjune as well.

A little sickness didn't keep Britney from showing up at Joey Morrissey's weekly party at ONE later on. An onlooker told NYDN, "She was in high spirits. [Spears] arrived in a little red dress, but she admired the fishnet [stockings] the dancers were wearing. She went downstairs and tried them on, but didn't like the way they looked with her dress. So she took off her dress and started putting on bikinis that the dancers wear. She stripped all of her clothes off and was totally naked in the dancers' room. She came out and got a T-shirt off of one of the waiters and danced like that till around 4 a.m." A source for People magazine said, "Britney came upstairs in a dancer bikini and a white busboy jacket. And that's what she walked out wearing."
