Nicole Richie came to court Friday to deal with a California DUI charge initially filed nearly eight months ago.

Richie, 25, pleaded to a California DUI charge of driving under the influence of drugs or alcohol.

Richie, 25, was sentenced to 96 hours, or four days, in jail. She will also be on probation, attend a multiple offender program, pay a substantial fine, etc.

The daughter of pop singer Lionel Richie was arrested early on Dec. 11 after witnesses reported seeing her black Mercedes-Benz sport utility vehicle headed the wrong way on a freeway in Burbank.

The California Highway Patrol said she was found parked in the car pool lane.

Richie told authorities she had smoked marijuana and taken the prescription painkiller Vicodin, a CHP officer said at the time.

No drugs were found on her or in the car.

Richie also had a June 2003 DUI conviction that made her eligible for a sentence of 90 days to a year in jail, a fine of $390 to $1,000 and suspension of her license.

Richie's situation follows that of Paris Hilton, her co-star on the reality TV show "The Simple Life." Hilton was released after spending about 23 days in custody for violating probation in an alcohol-related reckless driving case.
