Nicole Richie will spend four days in prison for driving the wrong way down a motorway while on drugs, reports The Sun. Richie, 25, was also ordered to go to rehab and fined £1,000. She has until September 28 to serve her sentence.
Richie was arrested in California in December for driving her Mercedes on the wrong side of the road while on her mobile. She admitted driving under the influence. It is her second driving under the influence conviction in five years.
