Move over people, Nicole Richie is making her way back to school. Not to get the formal education, but to get schooled on anti-drinking.

The socialite, who's six months pregnant with boyfriend Joel Madden's child, filed papers with the Superior Court of California on Wednesday September 26th, confirming that she has enrolled in Santa Barbara's SB 38 Multiple Offender Drinking Driver Program.

According to the Santa Barbara Council on Alcoholism and Drug Abuse Website, the Multiple Offender Drinking Driver Program, sometimes referred to as the SB-38 program, is for "people who have been convicted of DUI of alcohol or drugs on more than one occasion within a 7-year period." And over the course of the program, Richie will undergo 52 hours of group counseling, bi-weekly face-to-face interviews and 12 hours of alcohol education.

In addition to all, the $1,790 program also recommends, but doesn't require, participants to attend 12-step meetings. Individuals must complete the entire course before the Department of Motor Vehicles (DMV) will re-issue a driver's license, according to the program's Website.

Richie was arrested back on Dec. 11th 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 they found her parked in the car pool lane. She is said to have told authorities she had smoked marijuana and taken the prescription painkiller Vicodin. No drugs were found on her or in the car.

She then pleaded guilty to driving under the influence (DUI) on July 27 and thus sentenced to four days or 96 hours in jail, fined $2,048, and placed on three-years probation. The sentence was later on reduced to 90 hours because of time served when she was arrested.
