LATEST: 17 January 2006 is likely to become a 'black Tuesday' for socialite Paris Hilton who faces a double court session after being accused of verbal abuse in two separate lawsuits.

THE SIMPLE LIFE star stands accused of spewing "vicious lies" about an altercation with romantic rival ZETA GRAFF at a London nightclub in one suit and harassing a Los Angeles club boss in another.

Diamond heiress Graff is seeking upwards of $10 million (GBP5.5 million) in damages for comments Hilton made about her in a New York Post article last summer (05).

Hilton told the newspaper that the former lover of her ex-beau, PARIS LATSIS, went "berserk" in a London club and attempted to steal the US socialite's diamond necklace.

A 17 January (06) hearing is scheduled to consider Hilton's request for more information about the damages claim - the same day she's set to face charges she harassed and verbally abused Los Angeles promoter BRIAN QUINTANA.

Quintana alleges Hilton has badmouthed him in the press and threatened his life. He is seeking a restraining order.

A spokesman for Hilton says, "When all of the facts are revealed in this matter, they will show that the victim is, in fact, Paris Hilton."
