Kate and Wills at
Diana tribute concert
The tribute concert that Prince William and Prince Harry organized for their late mother, Princess Diana, was a rousing success, with more than 60,000 fans coming together yesterday at London's Wembley Stadium to see acts like Elton John, Duran Duran, Lily Allen, Kanye West and Nelly Furtado. And while the music rocked, spectators were just as interested to see William and his rumored on-again girlfriend, Kate Middleton. Kate was seated in the royal box, but she was two rows behind William - not by his side. Guess the couple's keeping things casual for now.
