VIDEO : See Prince George, Princess Charlotte's Cutest Moments at the Royal Wedding

Royal cuteness! Prince George and Princess Charlotte were quite the showstoppers at their uncle Prince Harry?s wedding to Meghan Markle on Saturday, May 19. Prince William and Duchess Kate?s two kids served as page boy and bridesmaid during the nuptials, while their youngest son, Prince Louis, stayed home with his nanny. The adorable pair were behind the bride as she walked down the aisle, and later posed for photos with the rest of the royal family on the steps of St George?s Chapel and waved at onlookers as the newlyweds got into an open carriage.
