Kate Middleton attended her second Olympic event in London this afternoon when she popped up at the swimming finals with Prince William. Kate chose a patriotic polka-dot top and bright red blazer for her latest appearance, after sitting in the stands earlier today to cheer on Great Britain's field hockey team in a blue jacket. It's been a busy week for Kate and William, who have been making the rounds since the opening ceremonies last Friday. The couple showed sweet PDA while watching track cycling yesterday and were likewise animated during this outing. Kate covered her face with her hands in between cheering and chatting with her husband. Make sure to check out all the Olympic fun as we continue to cover the action at the Games.
