Posh L.A bar, Winston’s has had enough of Britney Spears. The wig-wearing star has been barred from the exclusive club after allegedly forcing a bartender to switch dresses with her at a Halloween party. On October 29th, Brit insisted on switching Halloween costumes with a reluctant barmaid. (Who is now auctioning the costume on eBay.)

Club owners insist the troublemaker is no longer welcome at the venue because her antics have upset the regulars.

She loves hanging out at Winston’s because she’s sweet on the manager Harold Karsenty, who is “a total stud,” Brit insiders tell Life & Style Magazine.

“Harold loved the attention at first, but after a while he got sick of it… Britney caused nothing but drama,” says a club insider.
