CARPINTERIA, Calif. - Prince William, with his new wife, Kate, watching, took to the field for a charity polo match Saturday on the second day of a royal visit to Southern California.
The Duke of Cambridge scored four goals as his team went on to win the overall match. The crowd at the sun-splashed Santa Barbara Polo & Racquet Club rushed onto the field despite an announcer's pleas for them to return their seats, and finally security used a line of rope to push them back.
After stragglers were pushed back and decorum was restored, William's wife, the former Kate Middleton, presented each competitor a blue Tiffany & Co. box with a white ribbon, and a big silver trophy to her husband's team.
The last player to the podium was William. When the crowd yelled, "Kiss!," she obliged and gave him a slight embrace and a kiss on each cheek.
The Duke and Duchess of Cambridge arrived by helicopter in Carpinteria in Santa Barbara County, joining hundreds of well-heeled royal watchers who'd traveled long distances - and paid big sums - to see them.
The match was something of a recreational diversion for the couple, who otherwise are spending the bulk of their three-day trip to Southern California promoting British business ties to the U.S. and highlighting charitable work.
"My father, the Prince of Wales, and my brother, Harry, were as green as that grass outside when I told them I'd be here today," William told a reception where guests sipped champagne and whiskey. "Catherine and I have had a busy few days - so the prospect of being able to let loose this afternoon is wonderful for me."
As for whether he'll return to Santa Barbara, the duke reportedly joked, "That depends on the result out there today - I'm not a good loser."
William wore a white shirt and trousers with a blue blazer while Kate sported a silver and marble-grey, hand-painted silk dress by British designer Jenny Packham.
The cheap seats at the polo match cost $400, while anyone paying $4,000 for a VIP ticket would get a chance to hobnob with the royal newlyweds. The duchess will present the trophy to the winning polo team.
Celebrities spotted at the event included Rosario Dawson, Billy Zane, Jennifer Love Hewitt, Zoe Saldana, Rob Lowe, model-actress Molly Sims and musician Joe Jonas.
After the polo game, the duke and duchess will head to downtown Los Angeles to attend a black-tie event at the historic Belasco Theatre, where they will be guests of honor at a British Academy of Film and Television Arts dinner honoring 42 young British filmmakers.
The list of celebrities reportedly also attending reads like a who's who of Hollywood royalty: Tom Hanks, Nicole Kidman, Quentin Tarantino and Judd Apatow.
The duke and duchess arrived under sunny skies Friday after their nine-day trip to Canada, their first foreign excursion since getting married on April 29. Within minutes of landing, the couple headed directly to their first event, a technology summit in Beverly Hills aimed at promoting U.S. investment in British tech firms.
They then attended a private reception at the home of British Consul General Barbara Hay. Among the celebrities seen chatting at the event for the couple were British football star David Beckham and humorist Stephen Fry.
On Sunday, William and Kate will watch a dance at a nonprofit academy in the gritty Skid Row area of downtown then attend a job fair for U.S. servicemen and women transitioning to civilian life.
Though William has been to America before, it is Kate's first trip to the United States. William's late mother, Princess Diana, who would have turned 50 this month, charmed Americans when she visited in the 1980s.
