Kate Middleton and Prince William took in some tennis from the Royal Box at Wimbledon today, watching British player Andy Murray's quarter finals match on Center Court.

Middleton recycled a pleated, cream, cable-knit dress by Sarah Burton for Alexander McQueen - a design that she first modeled on the Canadian leg of the couple's North America tour last summer. Despite the repeat, the nautical number, which she paired with a quilted clutch, diamond earrings and her sparkling engagement ring, of course, scored an ace from Middleton's fashion following online.

The Duke and Duchess of Cambridge were greeted by fans as they took their seats before the first match on Center Court between Roger Federer and Mikhail Youzhny. The couple scored prime seats in the front row and shared the Royal Box with tennis royalty, former pros Andre Agassi and Stefi Graf.

Prince William and his wife are both tennis players and fans of the sport, even playing against one another from time to time, William revealed in 2011.

"We are both very competitive," he joked to reporters before the pair competed in a boat race on Prince Edward Island in July 2011. "She beats me at tennis and skiing but I am better at the rest."

The duo seemed to enjoy the close match between Spain's David Ferrer and Murray, who they came out to see play at Wimbledon last year.

Wimbledon, the prestigious tennis tournament which takes place at the All England Lawn Tennis and Croquet Club and is now in its ninth day of competition, is an annual hotspot for royals and socialites.

Prince Charles and Camilla paid a visit to Centre Court this week for the first time since 1970, the Associated Press reported. Middleton's family, sister Pippa and brother James, as well as her mother and father Carole and Michael, also scored seats in the Royal Box for matches earlier in the week.
