Paris Hilton and Zeta Graff, whose nightclub dance-floor cat fight played out in the gossip columns, have reached an undisclosed settlement in the $10 million slander suit filed by Graff in 2005, meaning Hilton won't be showing up in court again soon ... barring, of course, any drunk or suspended license driving incidents. "The resolution is confidential and no one will comment further," a spokesperson said in a press release.
