Pippa Middleton

Pippa Middleton

Pippa Middleton took her mother to watch the AEGON tennis championship on Thursday (13.06.13).

The sexy socialite - the sister of Duchess Catherine, the wife of Prince William - and her mum Carole went along to the Queen's Club in London to watch British Dan Evans play Juan Martin del Potro from Argentina.

Although the weather was far from warm, Pippa looked stunning in a mint green cardigan and matching knitted dress from Cashmere by Tania and she stayed refreshed by sipping on a Pimm's and lemonade drink.

The 29-year-old brunette - who is dating stockbroker Nico Jackson - was seen cheering on Dan loudly from her seat and chatted to her mother Carole, 58, between matches.

Pippa is now working for Vanity Fair magazine as a contributing editor and her first piece was all about her love of tennis and especially the annual Wimbledon tennis championship.

In the feature, she wrote: "I first went to Wimbledon when I was eight years old and already a very keen tennis player. During this first trip I acted on my childish tennis dreams and bought myself a postcard of the women's championship trophy, on which I wrote, 'I will win this one day,' with my signature below."

Pippa has reportedly been helping her sister Catherine - known as Kate Middleton before she got married - plan her baby shower, which is taking place at Kensington Palace on June 30, just a few weeks ahead of her due date.
