Pippa Middleton's Butt Has Become An International Sensation!

Pippa’s assets got a lot of attention during Kate and Will’s big day!

Her sister, Kate, may have scored the prince — but Pippa Middleton’s booty is getting quite the royal treatment!

The world got a good glimpse of Pippa’s fantastic fanny when the 27 year old showed off her sleek curves in a stunning Alexander McQueen gown at the Royal Wedding on April 29.

Her butt’s stirring up so much buzz, there’s even a Facebook group — “Pippa Middleton Ass Appreciation Society” — which has more than 101,000 fans and is growing rapidly!

And long after the wedding party, her phenomenal booty’s still the talk of the town! While exiting the Goring Hotel on April 30, Pippa was spotted donning a fitted blue blazer and a pair of skin-tight white jeans, which accentuated her behind nicely.

Looks like Pippa’s incredible bod runs in the Middleton family! So what’s YOUR favorite part of Pippa?
