Nicole Richie– daughter of Lionel, girlfriend of Joel, friend of Paris, enemy of carbs– was arrested for driving under the influence at 4:50 this morning. According to TMZ, two motorists called 911 after spotting her SUV driving the wrong way on the 134 freeway in Burbank, California.

FOXNews reports: When the California Highway Patrol responded, Richie was stopped in the carpool lane and was alone in the vehicle. When cops approached the vehicle, Richie was on her cell phone.

“She failed the field sobriety test at the field, so she was placed under arrest,” Workman said. “And she provided a sample for testing later on.”

Perhaps more disturbing than the fact Nicole allegedly admitted to smoking pot and taking Vicodin before getting behind the wheel is the fact that the booking sheet reveals Nicole is 5′1″ and 85 lbs. 85lbs! How heavy is that? Here are some comparisons–CLICK BELOW!
