Guess she can add another mug shot to her portfolio. Paris Hilton has been arrested for cocaine possession, Las Vegas police confirm. Police say they noticed a car leaving a trail of smoke that smelled like marijuana and pulled it over. The unnamed driver was also arrested for drug possession; Hilton was a passenger. She was held at Clark County Detention Center and released at 2:30 a.m. Saturday. During this year’s World Cup, Hilton was arrested in Port Elizabeth, South Africa, on suspicion of possession of marijuana, but her case was dismissed in a night court hearing. She spent 23 days in jail in 2007 for alcohol-related reckless driving, and publicly announced the experience caused her to party less.
