Socialite Paris Hilton is trying to persuade diamond heiress ZETA GRAFF to drop her $10 million (GBP5.8 million) defamation lawsuit against her - by wining and dining her. Hilton was spotted dining with Graff at Mr Chow's restaurant in Beverly Hills and then snapped entering the Roosevelt Hotel in Hollywood with her one-time love rival earlier this week (ends10MAR06). Graff sued Hilton last year (05), claiming the heiress defamed her by planting a false story in the New York Post. In the article, Hilton alleged Graff went "ballistic" at aLondon nightclub, attacking the hotel heiress and snatching a necklace. The feud reportedly started when Hilton discovered her then boyfriend, Greek shipping heir PARIS LATSIS, had dated 34-year-old Graff before her.
