Donald Trump broke royal protocol immediately after meeting King Charles and Queen Camilla on Monday afternoon.
The US President and First Lady Melania Trump welcomed the monarchs for a historic State Visit on the White House South Lawn before they headed inside for a reception.
Mr Trump gave the King a firm handshake, while the First Lady kissed the Queen on both cheeks, before the quartet stood and smiled for the cameras.
They then turned to head inside, but on the way in, President Trump gently touched the King's right arm while guiding him through the doors.
This is a breach of the unwritten protocol of never initiating physical contact with a royal.
Body language expert Judi James told the Daily Mail that the move "looked like a more political gesture" from the President, and demonstrated a "gesture of active, 'special' friendship".
It doesn't mark the first time Mr Trump has broken protocol by initiating physical contact with his "friend" King Charles.
During his trip in September 2025, he was seen grasping the monarch above the elbow during their initial greeting, setting the tone for what proved to be another handsy encounter between the two leaders.

Following the royal faux pas, the King and Queen sat down for tea with the President and First Lady at 1600 Pennsylvania Avenue.
They were then greeted with a tour of the First Lady's newly unveiled beehive, after the First Lady revealed the expansion to the executive residence's apiary programme last Friday, with the centrepiece being a hive crafted in the distinctive shape of the White House itself.
Later on, they attended a Garden Party at the British Embassy in Washington DC, which brought together an array of guests representing the transatlantic relationship between Britain and America.
