LAS VEGAS --- All-American party girl Paris Hilton was arrested late Friday night for cocaine possession, according to Las Vegas Police Department spokesman Martin Marcus.
Hilton (shown in a 2007 mug shot) was a passenger in a car that was stopped by police, reportedly after the officers smelled (and saw) marijuana smoke pouring from the vehicle's windows.
While the unnamed driver was also arrested, police then discovered the hotel heiress was in possession of cocaine.
After Hilton's arrest, she was held at the Clark County Detention Center before her release at about 2:30 a.m. PDT Saturday.
No one from the Hilton camp has been available for comment yet.
Hilton was recently detained for a short period of time when French offiicials found a small amount of marijuana in her possession. In 2007, she served 23 days in jail for reckless driving.
