Princess Charlotte and Princess Beatrice showed off their adorable, close bond at Prince Philip's memorial service. The 6yearold and her 8yearold brother, Prince George, accompanied parents Prince William and Kate Middleton on Tuesday to pay tribute to their late greatgrandfather. Charlotte charmed with her good behavior, but at one point, cameras caught a cute moment of her smile at her older cousin, Beatrice, and the princess immediately flashed her a big pearly white smile back!
