Who knew Pippa Middleton was such a tennis fan?!

While her sis Kate, now the Duchess of Cambridge, and Prince William were turning heads at the Epsom Derby in England, Pippa hopped the Channel and put in an appearance at the French Open.

And as heads bobbed left-to-right, following the tennis ball as it bounced between Rafael Nadal and Ivan Ljubicic, many eyes stopped to focus on the world's new "It" girl.

Middelton, 27, then jetted back to England to compete in the GE Blenheim Triathlon on Saturday. She's a sports fan AND an athlete!
