Kate Moss was out in London yesterday afternoon for a shopping trip to the Bonpoint children's store. She was joined by a female friend and Jamie Hince, who's back in England after a weekend away in Milan performing during the city's Fashion Week. Kate was picking up a few goodies from the shop to prep for her daughter's seventh birthday today. While Lila celebrates the milestone, a recent development in Kate's professional life has some wondering about her growing empire. She just joined the Performing Rights Society, which should allow her to collect royalties on songs she wrote with Pete Doherty and Babyshambles, as well as potentially pave the way for a future collaboration with Jamie.
