Kate Middleton and Prince William Watch Olympic Tennis

Kate Middleton was in Stella McCartney once again to join her husband, Prince William, at the Olympics today. It was the same blue frock that Kate wore nearly two weeks ago to an art opening at the National Portrait Gallery. William and Kate cheered on Great Britain's Andy Murray as he played in the quarterfinal of men's singles tennis against Nicolas Almagro of Spain. They're both big fans of Andy, having rooted for him during Wimbledon in June. Kate and William really got into the action, and even did the wave! Both royals have been busy supporting the Olympic Games, stepping out for equestrian and gymnastics events in recent days.
