Britney Spears has been barred from exclusive Los Angeles Britney Spears club Winston's after allegedly forcing a bartender to switch Britney Spears dresses with her at a Halloween party.

Club owners insist the pop stars Britney Spears is no longer welcome at the venue because Britney Spears her saucy antics have upset regulars.

On October 29 Spears reportedly insisted on switching Halloween Britney Spears costumes with a reluctant barmaid.

Friends tell Life and Style magazine Spears loves hanging out at Winston's because she's smitten with manager Harold Karsenty, who is "a total stud."

One Britney Spears venue insider says, "Harold loved the attention at first, but after a while he got sick of it. ... Britney caused nothing but drama."

The propaganda of the ban has upset Spears fans who use Winston's as a regular haunt. Stacey Kives tells Life & Style, "It was exciting when she was there. The whole bar would revolve around her."

I hear Britney Spears she's not banned at tacky sex shops yet, where "Spears fans" (which I take to mean paparazzi) can catch her giving quite a show at times.

How do you "force" someone to switch costumes with you? Did she threaten to sing or something?

This may be a sociological first: a stud named Harold.

maybe she threatened to run over her foot.

She upsets everything and everyone around her no matter where she goes and she goes all of the time - twice in one night to a gas station last night!
