Paris Hilton is at the centre of a legal fight in Germany after pulling out of a series of events she was scheduled to attend Friday and Saturday.

Promoters booked the socialite to appear at a number of industry events in Frankfurt, but Hilton refused to leave her hotel room in the city.

She then flew to Italy early on Saturday to judge a beauty pageant, snubbing one party she was supposed to attend with Frederic Prinz von Anhalt's adopted son Marcus, reported contactmusic.com.

It was reported that Hilton pulled out of her scheduled appearances due to an argument with her boyfriend, Doug Reinhardt, suggesting the hotel heiress was instructed not to attend the Saturday night event because it was being held in an erotic table dancing club.

"Paris Hilton has dishonoured 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," said Michael Marx, the organiser of a party at top club Mediastar.
