The Reason The Queen Is Giggling In This Photo With Prince Philip

But one particular image generated a lot of buzz online.

As Britain mourned the death of Prince Philip, photographs from just about every chapter of his long life circulated widely: There were images from his 1947 wedding to the future Queen Elizabeth II and of him serving in the Royal Navy. Of him line dancing in Canada, hosting the Obamas in London and rowing a boat across the Mediterranean. But one particular image generated a lot of buzz online. The year is 2003 and Philip stands in full ceremonial uniform and a traditional bearskin cap, ready to accompany the queen to a ceremony at Windsor Castle. But as she arrives, wearing a powder-blue ensemble and white gloves - a large grin spreads across her face. Together they chuckle, sharing a moment that some said was indicative of a lifetime of love. On social media, many wanted to know: What exactly were the "mischievous" pair laughing at?
