Socialite Paris Hilton was arrested last night for possession of cocaine, a Las Vegas Police spokesperson has confirmed. The sexy Paris, was a passenger in a vehicle that was stopped by Las Vegas police, after they smelled what they suspected was marijuana. "Officers noticed a vehicle leaving smoke trail of a controlled substance (and) made a stop based on that," Las Vegas police spokesman Marcus Martin told media outlets. The driver was arrested for drug possession and it was discovered Paris was in possession of cocaine. Paris was detained at the Clark County Detention Center and released at around 2:30 a.m. PT this morning. Paris is no stranger to problems with the law. She was arrested this summer after the Brazil-Netherlands World Cup match in Port Elizabeth, South Africa, on suspicion of possession of marijuana. The case was then dropped at a midnight court hearing. Hilton pleaded no contest in 2007 to alcohol-related reckless driving and was sentenced to 45 days in jail. After spending about 23 days in jail, Hilton told CNN television host Larry King that the experience caused her to re-evaluate the role partying played in her life. She said she wanted "to help raise money for kids and for breast cancer and multiple sclerosis."
