Pippa Middleton accused of enhancing her bottom

French author has claimed Ms Middleton fooled everyone by wearing a 'fake bottom' on the day of the Royal wedding

A French TV presenter has accused the Duchess of Cambridge’s sister of enhancing her posterior with some well-placed padding under her Alexander McQueen dress, creating “an optical illusion” and fooling us all during the Royal Wedding.

Pippa Middleton was little known to the masses until her rear caught the attention of a global audience throughout the service, where she acted as bridesmaid to her sister and ‘earned’ the nickname HRH (her Royal hotness).

Shortly after the 2011 wedding, her derriere was awarded its own Facebook group (the Pippa Middleton Ass Appreciation Society, an official website and even a Twitter account, proving so popular it almost threatened to overshadow the Duke and Duchess’ marital union.

But author Stephane Bern, described as a ‘Royal expert’ by some media outlets, has suggested the 30-year-old may have misled the public by sporting a fake bottom on the day.

His claim came as Ms Middleton took a research trip to the vineyards of Bordeaux earlier this week.

Speaking on his TV chat show, the journalist and radio host declared: “She had a false bottom. I repeat – she had a false bottom.

“You take her away from that and she has normal buttocks.”

Mr Bern went so far as to suggest her behind was an optical illusion, insisting that “there was a million people watching” and “it was the moment to show it.”

The speculation will probably not upset Ms Middleton, who in February explained to the Women in Advertising and Communications conference how the bridesmaid gown changed her life. She described feeling relieved the dress fit her on the day, but later felt that “in retrospect, it [fitted] a little too well."

"As I have found out, recognition has its upside, its downside and - you may say - its backside," the columnist added.
