Will, Kate Glam It Up in LA

(AP) 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.

Last night's soiree at the restored 1920s-era Belasco Theatre in downtown LA 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. The duchess wore a flowing lilac dress with white waistband by Alexander McQueen. Fans cheered as they strode a red carpet and the couple responded by walking over and shaking a few hands. "Before I start, I'd just like to thank Colin Firth for my opening line: I have a voice," William quipped to the star-studded audience. Today, the royal pair will go from the ritzy to the gritty, taking in a dance at a nonprofit academy in Skid Row. Click through the gallery to see more shots from their day in California.
