Nicole Richie, adopted daughter of Lionel, was stopped at 4:50 a.m. this morning for a DUI. According to police, the eighty-five pound starlet admitted to having smoked marijuana and taken Vicodin: however, she tested negative for alcohol. Like her long-time friend and FOX's Simple Life co-star, Paris Hilton, in a similar event earlier this year, she was very cooperative according to CHP officers. Reportedly, Richie had an earlier brush with the law in 2003 when she pled guilty to heroin possession: nevertheless, those charges were dismissed after she satisfied the stipulations of her probation. She is apparently being represented by Hollywood attorney Howard Weitzman in the current affair. Hopefully, this troubled young celeb will find needed help so that she will not endanger her life and the lives of others in the future.
