According to US reports, Britney raised eyebrows at the weekend with an impromptu public strip tease.
The skimpy clothes-loving songstress was at LA burlesque club 40 Deuce on Sunday night (December 17) with a group of mates - note: Paris Hilton was not in attendance - and was enjoying herself so much that she jumped up on stage between acts.
"Britney and some girlfriends gyrated for the crowd, with Spears, cigarette in hand, unzipping her top and baring her bra," reports the New York Daily News.
"She was having so much fun, the club's manager had to step in and remove her from the stage."
According to the report the 'Oops! I Did It Again' lady also surprised people with her choice of tipple - a heady mix of Champagne and Coca-Cola.
Bet there were a few burps chez Britters the next morning...
