Kate Moss vacationed in St. Tropez today with her daughter. The supermodel stripped off her shirt and wore only bikini bottoms as she jumped off a yacht into the ocean. After the dip, she toweled off and hung out on deck with friends. Kate also spent part of the day on the shore at Club 55, wearing a green, fringed dress as she soaked up the sun. Kate's new husband, Jamie Hince, who is currently on the road with The Kills, didn't join her for the trip. He and his bandmate Alison Mosshart are playing shows in the US and Japan this week, but Kate was by his side for the previous leg of their tour, which took them to Australia. Kate is now back in the French Riviera for the second time this Summer after spending part of her honeymoon there with Jamie. The newlyweds borrowed a yacht from Kate's longtime friend Topshop CEO Philip Green and spent about a week on the waters off of Italy and France.
