Nicole, In Hiding

Nicole Richie continued to play it cool the day after her arrest for driving while drugged out.

The Simple Life star slept Monday night at the Glendale home of her new boyfriend, Joel Madden, and on Tuesday the skinny stoner spent the day on the set of the new Good Charlotte video, filming in downtown Los Angeles.

When Richie was alerted that there were photographers lurking around the set, she fled to her boyfriend's trailer and kept under wraps when she left for the day.
