When you're Kate Beckinsale and you have millions of dollars, what else is there to do besides shop? Maybe make a movie here and there, but really unless you're Samuel Jackson or Christopher Walken, it doesn't take up that much of your time. Ah, the life of a rich Hollywood star. Something we all envy, minus their shitty relationships. And being constantly hounded by the press. And their general lack of touch with reality. Ok, so we just envy their money.
Also, I'm not sure who that guy is in the photos, but I assume it's her husband. I'm not a fan.
