Princess Beatrice and her boyfriend, Dave Clark, sat front row during the Wimbledon quarter-finals in London today. They checked out the match between Sabine Lisicki and Marion Bartoli, which ended with Sabine taking the win. Luckily the game took place under the roof of the Center Court stadium since thunderstorms and rain caused delays for other duos. The couple just returned from a trip to Cap d'Antibes where Princess Beatrice wore a bikini and Dave Clark went shirtless. Beatrice has been on the go all month, attending the Epsom Derby alongside Kate Middleton and Prince William and also checking out opening day of the Ascot Racecourse with her sister, Eugenie.
