Pippa Middleton, sister of Duchess of Cambridge, Kate Middleton, enjoyed some tennis matches at the 2011 French Open tournament at the Roland Garros stadium in Paris. One of the matches she watched was between Robin Soderling of Sweden and Gilles Simon of France. She also watched defending champion Rafael Nadal beat Ivan Ljubicic in his fourth round match. Pippa was seen with pals laughing and enjoying the match. The Daily Mail is reporting that Kate Middleton is believed to be presenting the prizes at Wimbledon this summer. She was wearing a scoop-necked black tee-shirt, a black and white skirt and oversized Gucci sunglasses.  IT seems as if she's wearing barely any make up. Pippa became an instant sensation last month with her form fitting Sarah Burton bridesmaid dress at her sister's wedding to Prince William.
