Socialite Paris Hilton has denied reports she is demanding fees for personal appearances in Las Vegas, insisting the figures quoted are "not accurate". The hotel heiress and sister Nicky have been accused of charging $500,000 (GBP250,000) a time to appear at party hotspots on New Year's Eve. A source tells the New York Post gossip column Page Six, "Paris and Nicky are shopping their partying ways to Vegas $500,000 - only they have the guts to ask for that amount - for a multiple-day New Year's Eve bash. "Paris will 'party' at a few spots and Nicky will bless the lucky host with a fashion show of her wares and model herself." But Hilton's spokesman Mike Sitrick has blasted the claims, saying, "That is not accurate."
