Nicole Richie - Arrested

Reality star was drugged-up when she drove SUV down the wrong side of Los Angeles freeway.

Nicole Richie was arrested this morning in Burbank, California, for driving under the influence. The Simple Life star was booked into the Glendale police department at 4:50 a.m. and released at 7:15 a.m.

Police pulled Richie over after witnesses reported her driving the wrong way on highway 134. Officials tell TMZ.com that Richie admitted to smoking pot and taking the prescription drug Vicodin.

Richie was arrested and charged with driving while under the influence of alcohol and/or drugs, which could bring jail or a $1,000 fine. She was released on $15,000 bail.

"She failed the field sobriety test at the field, so she was placed under arrest," a Glendale police officer told reporters. "And she provided a sample for testing later on."
