Queen Elizabeth II couldn't be with her surviving family at the coronation today, but we know she would've been proud of three of her great-grandchildren—Prince George, 9, Princess Charlotte, 8, and Prince Louis, 5—who showed off their best royal waves.
The three were seen waving to the crowds throughout the day as they rode with their parents, Prince William, 40, and Kate Middleton, 41. Perhaps one of the best moments was a video that saw Prince Louis waving through the window on his way to Westminster Abbey, which was shared by the @RoyalCentral Twitter account.
