If anyone was tempted to think that Britney Spears barfing all over her new boyfriend in her car was too much even for her, then that someone has another thing coming. According to reports in the media, immediately after said incident, the pop star and her boytoy traveled to Sin City for an entire weekend of fun and clubbing.

Yesterday, X17 had some pictures of Brit Brit's new piece, Isaac Cohen, a 25-year-old model and aspiring actor, sitting in her car while he tried to wipe some brownish stuff off his fingers, the shift gear and Britney herself. At the time, the semi-K-Fed lookalike said that the unidentified substance was not puke, as the photogs inferred, but peanut butter.

He said he had a jar full of it in his pocket and that it broke or it got opened in some mysterious way and that this is why he was all covered in it. Due to the lack of evidence, people would just have to go with his theory, if they are not willing to believe Britney capable of puking all over her boyfriend.

After the clean-up operation, the two lovebirds went to Las Vegas, where a three-day weekend of partying, boozing and smoking followed, again according to reports from the press. Britney had her new man checked in at the luxurious The Palms, a Playboy villa owned by Hugh Hefner, and equipped with anything from a jacuzzi/swimming pool in the suites to gyrating beds. For this, she took out no less than $40,000 per night!

Eyewitnesses say that, while in Vegas, the star and her 20-something entourage hit all the major gay clubs, where they danced, drunk and had some major fun. At one point, Britney even wound up at Pure, the same club where she was to host the New Year's Eve party and where she passed out an hour after midnight.

If one were to believe the hype, it was a weekend of debauchery and around-the-clock club hopping, with Britney as the master of ceremony. After all, it was her who said two weeks ago, 'What goes down in Vegas, stays in Vegas, right?'. Wrong!
