Nicole Richie, her husband, Joel Madden, and their kids, Harlow and Sparrow, pulled up to the South of France during their family yachting excursion around Europe. They hit the beach in St.-Tropez today, holding hands while walking along the water, and both of the little ones put on life jackets before boarding their boat again. Yesterday, Nicole showed skin in a crop top and snapped photos of both her kids on her iPhone while they spent the afternoon exploring. She and Joel doted on their daughter, Harlow, who took a ride on a carousel during their St.-Tropez day. Nicole and her family have been spending time on the friendly seas, and they made a yacht stop in Italy last week. On Wednesday, Nicole, Joel, and the kids relaxed on the deck of the vessel and also took to the pavement for a bit of shopping in Portofino where they met up with Magic Johnson and his wife, Cookie, for dinner.
