Interest in Kate's younger sister has exploded after her stunning appearance at the royal wedding. The royal wedding didn't just launch Kate Middleton the Duchess of Cambridge into the spotlight. The extravaganza watched around the world made her younger sister Pippa, also decked out in a stunning white Alexander McQueen dress, into an overnight celebrity. The Daily Mail called the famous maid of honor "the world's most eligible woman" and sites like BauerGriffinOnline.com have dedicated galleries to her scene-stealing green engagement dress. Even Pippa's backside gained fame on Facebook. Searches on Yahoo! have soared since the wedding: Fans of Pippa wanted to see "pippa middleton photos," "pippa middleton dress." They hope for a romance between "pippa middleton and prince harry" despite the fact that she's already dating Prince William's friend, retired cricket star Alex Loudon. She and Loudon, now a banker, have been together since December. Those who know Pippa, officially Philippa Charlotte Middleton, would not be surprised by her sudden celebrity. Born in 1983 and raised in Bucklebury, Berkshire, the tanner of the two sisters easily outshone her older sibling when the two children attended the girls' boarding school Downe House. According to Katie Nicholl, author of "The Making of a Royal Romance," "Pippa was the more beautiful of the two of them at that age. But Catherine was more determined, which seemed to set her apart." With Pippa's prospects looking so good, she may soon be donning the Issa dress to make an announcement of her own. Source: Yahoo
