Troubled singer Britney Spears has been banned from an exclusive hotel in Los Angeles after fellow guests complained about her behaviour, according to reports. The Toxic star is alleged to have shocked diners at the Chateau Marmont hotel's restaurant after she smeared food over her face - which led to her being thrown out of the establishment. A source tells British newspaper The Sun, "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." A source at the hotel adds, "Staff at the Chateau have been told she is not welcome. She constantly looked out of it when she came in and a few of the guests began to make noises. "The hotel acted before she made a big scene. No-one wants to be banned from staying at the Chateau.
