BEIJING, Sept. 29 (Xinhuanet) -- "Simple Life" star Nicole Richie has enrolled in an 18-month anti-drinking program, media reported Friday.

    The six-month-pregnant Nicole signed up for the SB 38 Alcohol Program on Sept. 26.

    The program is for "people who have been convicted of DUI of alcohol or drugs on more than one occasion within a 7 year period," according to the Santa Barbara Council on Alcoholism and Drug Abuse website.

    In the course, Richie will have to undergo 52 hours of group counseling, biweekly face-to-face interviews and 12 hours of alcohol education.

    Richie was arrested for DUI on Dec. 11 after she was spotted driving the wrong way down Highway 134 in southern California. She admitted to smoking marijuana and taking the painkiller Vicodin.

    She already had an alcohol-related conviction back in 2003.
