Hollywood royalty mingled with the real thing as the Duke and Duchess of Cambridge spent a sun-splashed day on the polo fields of Santa Barbara County followed by a diamond-studded night amid movie glitterati at the midpoint of their tour of California. Prince William wowed the crowd with four goals at his charity polo match then he and the former Kate Middleton headed by helicopter to downtown Los Angeles for a black-tie film industry event that drew Nicole Kidman, Tom Hanks, Barbra Streisand, Jack Black and Jennifer Lopez, among many others. On Sunday, the royal pair will go from the ritzy to the gritty — the royal couple will watch a dance at a nonprofit academy in the Skid Row area of downtown. “There's so much compassion in both of them,” said Los Angeles resident and royal-watcher Christian Kang. “I know they're going to Skid Row, and I think that's very good to see from someone in his position.” They're also slated to attend a job fair for US servicemen and women transitioning to civilian life. Saturday night's soiree at the restored 1920s-era Belasco Theatre in downtown Los Angeles was organized by the British Academy of Film and Television Arts, of which William is president, to promote up-and-coming British talent in the industry.
