Philippa Charlotte “Pippa” Middleton (born 6 September 1983) is the only sister of Catherine, Duchess of Cambridge. A party organiser, she is well known because of her sister and through the reporting of society news. On 29 April 2011, she was the maid of honour at her sister’s Royal wedding, which she helped to organise. Her role in the televised wedding resulted in widespread media coverage and public admiration for her dress and appearance

Now the world has some idea what Pippa Middleton’s form-fitting royal wedding gown was hiding.
A photo has emerged of Middleton wearing a bra and a skirt while dancing with a man wearing only boxers.
It’s unclear when the photo was taken.

Middleton isn’t the only one in her family who has had a photo scandal. Semi-nude photos of her brother James also have appeared.
After Pippa Middleton appeared last week at her sister Kate’s wedding to Prince William in the white gown, mesmerizing the male half of the 2 billion people watching around the world, social networking sites immediately went wild for her.
