Nicole Richie had a busy one in LA yesterday, starting with a business meeting in the afternoon. She traded her black skirt and leopard print booties for cutoffs and flats later when she and a friend took their kids out for ice cream. Nicole's oldest, her daughter Harlow, was decked out in her ballerina gear for the sweets run. The day about town came after Nicole and her husband, Joel Madden, wrapped up an overseas adventure. Joel and Nicole took Harlow and Sparrow to London for Disney's Princess Royal Court Celebration , and then came an adults-only Fashion Week extravaganza at the Spring 2012 Louis Vuitton show.
