Paris Hilton has been slapped with slander and harassment lawsuits that are headed for courtrooms this month.
The hotel heiress, 24, is accused in the suits of spewing "vicious lies" about an altercation with a romantic rival – diamond heiress-actress Zeta Graff – at a London nightclub last summer, and also badmouthing a business promoter.
Graff is seeking at least $10 million in damages following Hilton's comments last July in a story that appeared in the New York Post. The paper reported that Graff – who once dated Hilton's then-fiance, Greek shipping heir Paris Latsis – went "berserk" at the nightclub and attempted to strangle Hilton and steal her diamond necklace, according to legal papers.
Graff denies the report and insists that Hilton said "I'm going to destroy you" after trying to oust her from the club, the suit claims.
Former Hilton publicist Rob Shuter said in a deposition that Hilton asked him to help plant the story and that he gave the paper comments attributed to himself, Hilton and anonymous sources that were dictated by Hilton.
A Jan. 17 hearing is scheduled near Los Angeles to consider Hilton's request for more information about the damages claim. Hilton spokesman Elliot Mintz declined to comment on the case, the Associated Press reports.
A hearing also is set for the same day on the second lawsuit, in which promoter Brian Quintana, 37, alleges that Hilton harassed and badmouthed him in the news media and threatened his life. He is seeking a restraining order.
"I can assure you that when all of the facts are revealed in this matter, they will show that the victim is, in fact, Paris Hilton," Hilton's spokesman said.
