"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.
