Prince William & Kate Middleton Send Orlando 'Deepest Condolences'

Prince William and Kate Middleton mourned and paid their respects to the Orlando shooting victims all the way from the U.K.

The Duke and Duchess of Cambridge signed a book of condolence Tuesday inside the U.S. Embassy in London ... with an American flag serving as their backdrop. 

If the look on their faces didn't say enough ... their words did.
