Yesterday, key members of The Firm turned out at Westminster Abbey for this year's Commonwealth Day Service and, before taking their seats, King Charles and Queen Camilla exchanged small talk with the rest of the family.
The couple were seen chatting away to the Prince and Princess of Wales and the new Duke and Duchess of Edinburgh, as well as Princess Anne and her husband, writes The Mirror.
However, many fans of the royal family who watched the service were left confused as to why Kate didn't curtsy to her father-in-law.
