Kate Moss was in leather this morning on her way into London's Dorchester Hotel. The new face of Isabel Marant met up with friends for lunch after a particularly social few days — she was the guest of honor on Monday at a new Mario Testino exhibit dedicated to photos spanning her career. Kate is no stranger to a late night out, but according to Mario, she still gets shy at big events. He said, "Believe it or not, she is shy. I go to events with her and I am, like, 'What's the matter with you?' and she is, like, shaking, nervous."
