Britney Spears "Falls Asleep" at New Year's Party, Possibly Makes Out With Matt Leinart

The amazing Britney Spears was exhausted - not drunk - during a New Year's Eve party in Las Vegas, according to her representative.

"By about one o'clock, she was just done, so we took her out. [Britney Spears] was not drunk. She was just tired and falling asleep," says Larry Rudolph, her manager.

Monday, reports circulated that the 25-year-old mother of two fainted and had to be carried out of a Ceasars Palace's Pure nightclub in Sin City, where she was hosting a New Year's party. Instead, Rudolph said Spears walked out of the club and did not seek medical attention.

"There is nothing out of the ordinary here," he said.

A source at Pure corroborates his claim that this was not a Nicole Richie-style fainting episode.

"She was absolutely not carried out of the club. Her security and Pure's security walked her out... She didn't pass out or faint or any of that."

It would certainly make a funnier story if Britney passed out drunk at (or went commando to) the party, but maybe the new mom was finally acting like one - and falling asleep early! Before her exit, Britney had a good time with friends such as Brian Friedman (below).

In other Britney news, she was reportedly seen sucking face with Arizona Cardinals quarterback Matt Leinart Friday. The former USC star and Heisman winner, who just welcomed his first child with ex-girlfriend (or maybe current girlfriend) Brynn Cameron, has also been linked to Paris Hilton and Kristin Cavallari in the past year.

The guy's a player. No, really, he is - he plays pro football!

Lastly, a judge dismissed the lawsuit filed by Britney against Us Weekly, which speculated on the rumored Britney Spears sex tape late last year. The judge said Britney Spears actively fosters a sexual energy, makes money off her sexuality and various sexual antics (such as kissing Madonna), so there was no damage to her reputation.

Lesson learned: If you want to want to claim someone damaged your precious reputation by printing false sex tape rumors, don't go parading around in no pants and offering up a crotch shot to any photographer within sight.
