Kate Moss left the Ritz hotel in Paris yesterday with a Longchamp bag in hand, but was back in her hometown of London today for a shopping trip with her good friend Sadie Frost. Sadie and Kate stopped by the Vivienne Westwood store together shortly after Kate arrived home. The supermodel spent much of her November so far in France, reuniting for romantic dates with her husband Jamie Hince when he had brief breaks from touring Europe with his band, The Kills. Kate has been enjoying some time off lately after doing a whirlwind of press for Rimmel earlier in the Fall. Meanwhile, her younger half-sister is poised to be the next famous name in the family. Model Lottie Moss recently landed an agent and her first-ever shoot is already generating quite a bit of excitement in the fashion world. Pictures of Lottie from Kate and Jamie's wedding in July sparked interest among modeling agents, and now it looks as though the 13-year-old is planning to follow in her sibling's footsteps!
