Born Philippa Charlotte Middleton on September 6, 1983 in Reading, Berkshire, England, she first got media's attention with her appearance on the Royal wedding of Prince William and Catherine in 2011. Pipa's simple yet gorgeous Alexander McQueen gown, as well as the similarity in age and looks among the sisters became some of the most-discussed sidelights when Pipa served as Kate's maid of honor at her big day. Subsequently, her popularity reached global proportions, often reviving lengthy press coverage regarding her lifestyle, social life or the way she dresses. After she took a degree in Literature from the University of Edinburgh in 2007, Pipa landed a job at a London-based event organizing company Table Talk. Soon, she became a leading socialite in London circles, and was also named Britain's most eligible 'society singleton' of 2008 by Tatler magazine. Rising to the ranks of a celebrity in her own right, Pippa Middleton published a book titled Celebrate in 2012. It's a piece of writing described as "a one-stop guide to entertaining throughout the British year."
