See Prince William and Kate Middleton's Touching Tribute to the Victims of the Paris Attacks

Prince William and Kate Middleton took the time today to pay their respects to the victims of the terror attacks in Paris, and it was a touching moment to say the least. Dressed in somber ensembles, the Duke and Duchess of Cambridge appeared at the French embassy in London, where they signed the book of condolence.

"To all those who have died and were injured in the heartless attacks in Paris, and to all the people in France: nos plus sincères condoléances," William wrote in the book, finishing his note with a French phrase meaning "Our most sincere condolences." He signed his note "Will," while Middleton signed "Catherine" underneath.

The Duchess opted for a conservative charcoal gray skirt suit for the occasion, while Prince William wore a dark suit and maroon tie. Kensington Palace tweeted about their appearance, including a photo of them signing the book along with a close-up of their poignant message.
