Kate may no longer be a royal-in-waiting, but she's quickly developing a reputation as a princess - of partying. The 25-year-old has been a regular at her favourite London night spots since splitting from William, but that's not her only new habit - she appears to have taken up smoking. During a yet another night out at London's Boujis with her sister Pippa, Kate was caught with a packet of cigarettes peeping out of her handbag. Always making sure her behaviour was fit for a Queen during her courtship with William, Kate has clearly dropped her guard - and squeaky clean image. Kate looked stylish in a monochrome print dress cinched in by a thick belt and a black cardigan.
