A new year, a new embarrassment. Britney Spears' manager is seeking to snuff talk that the popstress collapsed shortly after ringing in 2007, due to excessive partying that, by some accounts, included helping drain a $5,000 bottle of Dom Perignon. "She was not drunk. She was just tired and falling asleep," the rep tells the Associated Press, accounting for reports that Spears was led/carried out of Las Vegas' PURE nightclub by her bodyguards. "There is nothing out of the ordinary here." Indeed, as TVGuide.com's own Angel Cohn just noted, the demands of motherhood do take their toll on a person.
