Kate Middleton joined her fellow Royals (in the appropriately named Royal Box) to watch a special concert in honor of Queen Elizabeth's Diamond Jubilee at Buckingham Palace this evening. Wearing a navy blazer and a blue floral-patterned dress, she waved a novelty flag along to performances by musicians including Paul McCartney, Grace Jones, and Kylie Minogue.
