Kate Moss threw on a black hat to shop around London with her assistant, Fiona, yesterday afternoon, but by the evening she slipped into her latest floor-length dinner look to join pals, like Pulp frontman Jarvis Cocker, for a '70s-themed dinner at a friend's house. The supermodel didn't arrive empty-handed, though, since she showed up holding a box of After-Eight mints. She switched fur jackets and headed out this morning in her favorite colorful number to do a yoga class with Fiona before meeting up with her hairstylist buddy James Brown for a Japanese lunch. Kate, whose new commercial for Dior lipsticks is out, is home in England after her recent adventures at Paris Fashion Week. Her fiancé, Jamie Hince, didn't join her as he was off to NYC for a show with The Kills, but Kate's struck about a relationship with another musician in the meantime — she and Kanye West apparently crossed paths in France and he invited her to join him in Texas at SXSW.
