In the images, which were taken in the gardens of Clarence House, Charles and Camilla sit with Prince George and Charlotte, while Kate, William, Harry and Meghan stand behind.
The first photo shows the family smiling perfectly to the camera, coordinating their outfits in shades of white and blue. But it's the second image that has everyone talking.
In the royal's most candid photo yet, Prince George sits on his grandfather's lap with a huge smile on his face, while Camilla points at the camera for Charlotte and Meghan bursts out laughing at the back.
The Duchess of Sussex opted to wear a look by her wedding dress designer, Givenchy, while the Duchess of Cambridge wore a polka dot dress by London-based designer Alessandra Rich.
If Kate's outfit looks familiar, it's not because the mother-of-three has worn it before, rather Abigail Spencer, one of Meghan's Suits costars, debuted it at the royal wedding back in May.
