The promoters booked the 28-year-old beauty to appear at a number of industry events, but mysterious circumstances led to Hilton refusing to attend them.
She snubbed one party in Frankfurt, Germany, where she was expected to be a guest of Hungarian royal Frederic Prinz von Anhalt's adopted son Marcus. The hotel heiress was also to appear in top store Mediastar to choose the winner of a contest. The store bosses are now planning to sue her for 7.3 million dollars.
German newspaper Bild reports a 34 million-dollar class action suit is being planned.
"Mediastar is not alone with the lawsuit. Paris Hilton also pulled out of appearances in Italy, postponed flights, threw the whole programme over. After examination of all the facts and contracts it (suit) can even become more than 34 million dollars," Contactmusic quoted Michael Marx, who organised the events in Germany, as saying.
However, Hilton has hit back at the claims, insisting she was misled by promoters into making the agreement.
"On arriving in Germany Miss Hilton's security visited the 'night club' booked for the appearance and discovered it was a strip club, the venue had been misrepresented to Miss Hilton by the talent promoters. Miss Hilton does not support or endorse strip clubs and this type of establishment," said Hilton's spokesperson.
"Given this blatant and exploitive misrepresentation, the promoters were in material breach of their contract and Miss Hilton was, consequently, excused from further obligation to appear and instead remained in the privacy of her hotel. Any other reports of events from this night are fabricated and false. Miss Hilton did honour the remainder of her agreement with the promoters and attended the additional three events in Italy," the spokesperson added.
