Prince William and Kate Middleton Red Carpet Pictures at War Horse London Premiere

Prince William held an umbrella for his wife Kate yesterday evening at the London premiere of War Horse. The couple turned out for the UK screening of the Steven Spielberg-directed project, and rubbed shoulders on the red carpet with some of the movie's stars like Tom Hiddleston, Jeremy Irvine and Emily Watson. They also said hello to various servicemen and women who'd been invited. William looked handsome in his tux, while Kate wore a black lace dress from one of her family's favourite designers, Alice Temperley. The royals turned out because the evening was organised in support of the Foundation of Prince William and Prince Harry.

Steven was evidently touched to see the Duke and Duchess of Cambridge there. Steven Spielberg said of William and Kate, "It's a very prestigious honour because they represent an entirely new era in British royalty that has the entire world excited. When they came to America, that was one of the most exciting events, I think, that we've enjoyed for some time, so it's such an honour to be here in the UK to be able to meet them and to be able to show them, and all of us, War Horse." Following the event, William and Kate attended a private reception with the cast at Buckingham Palace. We can expect even more partying today, as it's Kate's 30th birthday!
