Sources tell the paper that Pure nightclub in Las Vegas wants to cancel her almost half-million dollar appearance fee, after she violated the contract. “Britney failed to spend the agreed amount of time in the club, because she had to be helped out after collapsing,” alleges a close source.

The club is “furious” with her because of her PR spin that she merely fell asleep – implying the place is boring.

“Britney had a great time,” said a club spokeswoman. “We love her and can’t wait for her to come back.”

But an insider familiar with the club says: “The moment a celebrity gets into one of those deals they are on the clock. They are watched to the minute, and they are not allowed to leave early. It’s a contractual obligation.”

In other news, turned off by her binge drinking, drug rumors and criticism of her parenting, Britney’s record company Jive Records has had enough reports NW Magazine.

Sources say a successful CD from the singer would be enough to make the label turn a blind eye to her antics, but they are already less than impressed by the quality of her newly recorded tracks. “She thinks it’s the making of a great album,” says a source. “They don’t.”

The company is now facing the expense of re-recording some songs and bringing in better producers. Insiders say they are only willing to do this if Britney cleans up her act first.
