An arrest report obtained by the AP says Paris Hilton denied owning the purse in which police say they found less than a gram of cocaine after a traffic stop. A police lieutenant says in the report obtained Monday that the 29-year-old celebrity socialite acknowledged owning lip balm and an asthma medication also found in the purse late Friday when she was pulled over on the Las Vegas Strip. But she denied the cocaine and purse were hers. Hilton's facing a felony drug charge. Her lawyer says he's not commenting now, but plans to challenge the arrest in court. Hilton's boyfriend, 34-year-old Las Vegas nightclub mogul Cy Waits, also was arrested. He's facing a misdemeanor charge of driving under the influence of drugs or alcohol.
