Clad in a white cable-knit Alexander McQueen ensemble, the Duchess of Cambridge, 30, exchanged a series of loving glances with her husband of 15 months during the game. After the Federer-Youzhny match, the royals stuck around to root for Britain's Andy Murray as he faced off against Spain's David Ferre.

Prince William, 30, and Kate weren't the only royals to take in the famed tennis matches. Last week, William's father, Prince Charles, made his first visit to Wimbledon since 1970. Middleton's sister Pippa, brother James, and parents, Carole and Mike, were also spotted taking in games seated in the Royal box at Wimbledon.
