The Duke & Duchess of Cambridge braved the rainy weather to attend the London premiere of War Horse on Sunday night.
Being the gentleman that he is, William shielded Kate from the rain with an umbrella while she walked down the red carpet in a black lace Alice by Temperley gown.
The Duchess completed her look with a Pretty Ballerina velvet clutch and her usual soft curls.
