Pippa Middleton was spotted on her way to work in London yesterday morning. She also made a stylish commute on Friday, but apparently left the city afterward to spend the weekend at her parents' Bucklebury home with boyfriend Alex Loudon. Pippa has been working as an event planner and writer for the last few years, both for her parents' company, Party Pieces, and another firm called Table Talk. She may, though, be entering a new phase in her career. Pippa is rumoured to be linking up part time with her ex George Percy, with whom she just shared a vacation in Spain, and his geothermal energy company. She's to help George and his Cluff Geothermal to lobby the government for permission to test out their method of using hot water stored underground to generate electricity within the UK. Meanwhile, her sister Kate recently returned from a luxurious 10-day honeymoon in the Seychelles with husband Prince William and met with President Barack Obama and First Lady Michelle during their UK visit.
