Kate Middleton‘s main concern for nearly the last decade has been to behave all prime and proper like a future princess should. On April 29, Kate became Catherine Middleton, Duchess of Cambridge when she wed Prince William, which means she has to keep her partying under wraps. Pippa Middleton, 27, has yet to learn that lesson.
