PIPPA Middleton showed how to stay cool in the heatwave today as she stepped out to meet with friends. The famous sister met with friends for a coffee in the summer sunshine and looked at ease in the hot weather. Wearing a white linen dress and red accessories, Pippa stood out in the heatwave that has seen temperatures in the UK soar to 83 F. Pippa has soared to global notoriety after her appearance at her royal sister\'s wedding, particularly in America. The 28-year-old, who created a storm after she appeared at London Fashion Week, has now inspired thousands across the pond who want their own shapely behind. Cosmetic surgeons in the U.S. are reporting a huge rise in the number of women wanting buttock operations so that they look like her. Pippa is currently in a long-term relationship with city worker Alex Loudon and is rumoured to be moving in with him soon.
