Yesterday the royal family welcomed the US President, Donald Trump, to British soil, with an initial meeting at Buckingham Palace.
Almost all senior members of the family attended events with the President and First Lady, Melania Trump, throughout the course of the day - from Prince Charles and Camilla, to the Queen and Prince Harry.
For the Trumps second meeting of the day, they headed to Clarence House, for a tea with Prince Charles and the Duchess of Cornwall.
But as the foursome were leaving the room where they had posed for photos, Duchess Camilla proved one of the highlights of the day, with an hilarious move.

As her husband and Donald Trump headed out, she turned back around to the waiting media, and shared a tounge-in-cheek wink with the photographers.
The funny moment was captured on Sky News, and it certainly didn't go unnoticed on social media, having been shared by royal editor Charlie Proctor.
Royal fans seemed to love Camilla's seeming quip at the unusual situation, with one writing, 'She's played a blinder all day. Camilla you go girl 👊😊'
While another commented, '🤣 Go Camilla- I heard she had a great sense of humor.', and a third follower said, 'Omg I think I love Camilla!!!! This is fantastic can’t stop watching 😂🤣👏'.
And a fourth wrote, 'She's got a seriously awesome sense of humor.'

Of course, it's not clear exactly what Camilla was winking about. But many royal fans online have taken the assumption that the Duchess was perhaps making a light-hearted joke about the visit from a controversial President. One said, 'Top trolling Camilla 😂'.
Later on Monday evening, Charles, Camilla, the Queen and the Duke and Duchess of Cambridge headed back to Buckingham Palace for the State Banquet, which saw both Trump and the Queen make speeches praising the UK and America's special relationship.
President Trump finished his speech by saying, "On behalf of all Americans, I offer a toast to the eternal friendship of our people, the vitality of our nations, and to the long cherished and truly remarkable reign of Her Majesty the Queen."
