Parties! The style, stars and scoop from Hollywood's hottest events

When Princes William and Harry announced that they were organizing a concert to celebrate their mother's life, Fergie, Kanye West and Duran Duran were just some of the music legends that volunteered to take the stage. "What better people to do it?" the American Duchess—who wore a dress from British label Marchesa for the occasion—told People of the brothers' royal efforts. "They threw an amazing party for her. She would be so proud of them." The evening of song and remembrance benefited many of the charities to which Diana was dedicated.
