William and Kate popped into the Royal Box at Wimbledon to watch the men's quarter-finals. Kate, who is a big fan of Roger Federer, cheered the tennis champ as he battled and beat Russia's Mikhail Youzhny. The two stayed to watch some of Britain's Andy Murray's game afterward, but left before the athlete won his match.
