Britney Spears' manager has played down reports she had to be carried from a Las Vegas nightclub shortly after counting in the New Year.
Spears has been partying hard in recent months
Reports had claimed Spears collapsed after drinking champagne and had to be carried out by security guards.
But manager Larry Rudolph said: "She was not drunk. She was just tired and falling asleep."
He added that the 25-year old singer "was just done" and walked out of the venue and did not seek medical help.
She was hired to host the festivities at Ceasars Palace's Pure nightclub.
Reports had said she had been carried from the rear exit of the venue by minders, with a coat covering her head.
Mother-of-two Spears has been making headlines with her partying lifestyle since parting with her husband of two years, Kevin Federline.
