Match point: Pippa Middleton.

The world's most famous maid of honor caught the tennis match between Andy Roddick and Kevin Anderson in London on Thursday.

The match, which Pippa Middleton watched with her former roommate George Percy, took place at the AEGON Championship in London, which is considered a warm-up for Wimbledon. The Wimbledon tournament is set to begin later this month.

Pippa was donning a white summer dress with a denim jacket, wedges and sunglasses while chatting with her friend, Percy. Her and Percy took a trip to Spain together last month. Photos captured Pippa partying in Madrid as well as rowing Madrid's Retiro Park.

Percy is Pippa's old college roommate from the University of Edinburgh. He is the son of the Duke of Northumberland. While rumors speculated the two were dating, it turns out the two are just friends.

If anything were ever to happen with George, Pippa would be the Duchess of Northumberland one day and probably richer than Kate, an Edinburgh source told People.com

Pippa is allegedly dating businessman Alex Loudon, who was her date to the royal wedding.
