Nicole Richie, the star of the television show “A Simple Life” and the daughter of singer Lionel Richie, was sentenced and placed three years in probation. She will also pay a $2,048 fine.

Also she was ordered to complete a 21-day alcohol education course. Last year in December Nicole Richie was arrested for driving under influence after a police patrol was alerted that her 2005 black Mercedes SUV was going the wrong way on an Altadena, California freeway.

After she was arrested, Richie admitted to the police officers she had smoked marijuana and taken Vicodin, a prescription painkiller.

Nicole Richie admitted she is guilty, although in a preliminary trial back in February she denied the allegations.

She had already been convicted for drunken driving in June 2003. Under California law, two convictions within a 10-year period can result in a jail sentence

Richie will have to complete his jail sentence until September 28 and Los Angeles County Superior Court Commissioner Steve Lubell warned the star that she would "go to County Jail" if she violated the terms of her probation.

In the recent weeks, the media reported that Nicole Richie might be pregnant with Good Charlotte rocker Joel Madden, who was with her today.
