Kate Middleton and Prince William may be an ocean away from the violent tragedy that unfolded inside the Orlando nightclub on Saturday night, but they share America's pain. In a show of solidarity, The Duke and Duchess of Cambridge made a surprise visit to the U.S. Embassy in London this morning to express their condolences to the victims of the shooting that claimed 49 lives.

The royal couple was greeted by U.S. Ambassador Matthew Barzun before signing a book of condolences, started by the embassy following the attack, set up beneath a flag representing LGBT rights donated by The Kaleidoscope Trust.

With his wife by his side, and after a brief pause, Prince William bent down to add his message to the pages. "With our deepest condolences and with our thoughts and prayers to all those affected," he wrote alongside his signature. The duchess followed, signing "Catherine" to his words.

The duke and duchess, who wore an understated black and white patterned dress with a black cardigan for the somber occasion, then reportedly had a short meeting with the U.S. Embassy's LGBT network, GLIFAA.

Although Prince Harry wasn't in attendance, we know the recent events must be weighing heavily on the red-headed royal, who recently spent a significant amount of time in Orlando for this year's Invictus Games.
