The pop singer was told she was not welcome at the celebrity hotspot after a string of complaints about her 'odd' behaviour.
As to what this 'odd behaviour' was, well it seems that Britney smeared a plate of top-notch food over her face while dining at the hotel, leaving other diners stunned.
The diners were so shocked and outraged by Britney's antics, that they demanded management show the singer the door.
"The diners were disgusted. You wouldn't expect that from a teenager in a fast-food joint. Royalty have dined in this restaurant. Her behaviour was totally unacceptable," The Sun quoted a source, as saying.
Another source reveals: "Staff at the Chateau have been told she is not welcome. She constantly looked out of it when she came in and the guests began to make noises. The hotel acted before she made a huge scene.
"No one wants to be banned from staying at the Chateau.
"If she was trying to make a real go of her comeback then the people who visit the Chateau are the ones who could make it happen."
