Paris Hilton is facing legal action in Germany after pulling out of a series of events she was scheduled to attend in the country last weekend.

Promoters booked the heiress to appear at a number of industry events in Frankfurt, but Paris baffled them by refusing to leave her hotel room. She then reportedly flew to Italy early Saturday to judge a beauty pageant, snubbing a party she was supposed to attend with Frederic Prinz von Anhalt’s adopted son Marcus.

Sources tell German newspaper Bild that Paris pulled out of her scheduled appearances due to an argument with her boyfriend, Doug Reinhardt, who reportedly asked the socialite to stay away from one event because its was held at a venue known for erotic table-dancing.

“Paris Hilton has dishonored all appointments and contracts – the dinner with 18 high-ranking guests, the appearance at the bar, the autograph session at Mediastar. We are incredibly disappointed,” says Michael Marx, the promoter of one party at Frankfurt hotspot Mediastar.
