Nicole Richie pleaded guilty today to driving under the influence of drugs and was sentenced to about four days in jail and fined by a Court Commissioner Steven K. Lubell who said she was lucky nobody was killed when she drove the wrong way on a freeway. Wearing a loose-fitting Moschino black dress (possibly concealing a rumored pregnancy), oversized glasses, and hair conservatively pulled back, Richie showed up 10 minutes early for her 8:30 a.m hearing, arm-in-arm with her boyfriend, Joel Madden, who was also dressed in all black. Matching her somber outfit, Richie’s mood was described as serious but not emotional as she was sentenced to a plea agreement of jail time and a fine of $2,048 worked out between prosecutors and her lawyers. Richie will serve three years of probation and was warned that she would go to county jail for a year if she violated the terms of agreement.
