Nicole Richie was at Neiman Marcus in Coral Gables, FL, today to host a trunk show for her latest Winter Kate collection. Nicole sat down to chat about her line sporting a boho maxidress and braids. She talked a bit about as her career as an author and posed with her latest title, Priceless, during her visit to the department store. The starlet headed south for the appearance shortly after Joel Madden returned to LA from the overseas leg of his Good Charlotte tour. While he was away, Nicole stayed busy with their little ones, Harlow and Sparrow, at home, but also took some time out for herself. She was spotted fitting in some workouts with celebrity fitness guru Tracy Anderson, and also hit up a Prince concert with her girlfriends before hopping on a plane to show off her new designs this afternoon.
