Nicole Richie was back in her leopard print coat and Christian Louboutins for a shopping outing in Paris this afternoon. She took a break from the Fashion Week shows but got her fix by indulging in retail therapy at the French outposts of Celine and Isabel Marant. Nicole's solo trip overseas is perfectly timed with Good Charlotte's US tour, which kicked off this week in Atlanta. Joel Madden brought Harlow and Sparrow on the road with the band. He has a little help from his brother Benji, though, on their most recent stop in Washington DC.
