Now Pippa Middleton is no stranger. The day she walked down the aisle at Westminister Abby with her sister Catherine Middleton in a hip-hugging McQueen gown by Sarah Burton, the world and Prince Harry took notice of her taut and round buttocks. She has overnight become the ‘Poster Girl’.

Now somebody discovered an old picture of Pippa, the 27-year-old sister of Duchess Catherine stripped down to her bra and jiggling her bootie with a scantily-clad dude. As if there was any doubt about it, it appears that Pippa Middleton knows how to have a good time! Check out Kate’s taut body in a bikini too!
