Nicole Richie was arrested early Monday for investigation of driving under the influence of alcohol, authorities said.

California Highway Patrol officers took Richie, 25, into custody without incident after she failed a field sobriety test, CHP Officer Todd Workman said.

Her black Mercedes sport utility vehicle was stopped in the car pool lane of State Highway 134 when officers arrived.

Authorities said they received 911 calls about a car going the wrong way on the freeway and the car matched the description of Richie's.

Richie, star of "The Simple Life" reality series and daughter of pop singer
Lionel Richie, was booked in Glendale, tested for drugs and released later Monday morning, Workman said. He said the results of the drug test hadn't been determined.

TMZ has learned that Nicole Richie was arrested for DUI early Monday morning. She was booked at 4:50 a.m this morning and was released 45 minutes ago. The booking sheet reveals Richie is 5'1" and 85 lbs.

Richie SUV was spotted by two motorists going the wrong way on the 134 Freeway in Burbank. The drivers called 911.

When the CHP responded, Richie was stopped in the carpool lane and was alone in the vehicle. When cops approached the vehicle, Richie was on her cellphone.

Law enforcement officers tell TMZ Nicole Richie admitted she had taken Vicodin and smoked pot.

A preliminary alcohol screening device revealed that Nicole was not under the influence of alcohol.
