The Pippa Middleton A** Appreciation Society on Facebook now has 216,149 members all devoted to honoring her regal derriere.
The Royal Maid Of Honor caught the eyes of the world when she wore a figure hugging Sarah Burton white dress at her sister Kate Middleton’s wedding to Prince William on April 29, 2011.
The Facebook fan page is devoted entirely to Pippa’s butt with an array of images of the now famous English beauty.
Wonder what her boyfriend Alex Loudon thinks of all the attention surrounding Pippa’s now famous booty?
