Kate Middleton was seen breaking an 'unwritten' royal rule while greeting well-wishers during a visit this week.
The Princess of Wales had been making an official appearance in Scarborough when a royal fan asked her to take a picture, before he put his arm around her.
Grabbing her attention, Kate was seen more than happy to smile for the photograph, and had chatted to the gentleman before moving on past the crowd.

According to the Daily Mirror, there are no official codes of behaviour when meeting a member of the Royal Family, however an unwritten rule means you should not go beyond a handshake.
Despite the protocol, in recent years it has been more common to see a younger royal engage more with the crowds, with Prince William seen doing similar when he hugged a 66-year-old man during a walkabout in Scotland.
Over summer, he also hugged the Lionesses after their historic Euros win.
On multiple occasions, Meghan Markle was hugged and kissed by royal fans, who shared conversations and photos with the Duchess of Sussex.
Meghan also hugged royal fans who gathered in Windsor after Queen Elizabeth II died in September.
Sophie Wessex was also pictured hugging a young boy who was holding a teddy bear in Manchester during a vigil for the late monarch.
Today, Prince William and Catherine visited the seaside town of Scarborough to launch funding to support young people's mental health.
William and Kate were greeted by a cheering crowd as they started their day at The Street - a community hub that supports local organisations to grow and develop their services.
Kate was wearing a camel-coloured overcoat over a similar coloured outfit, while William was sporting a burgundy jumper and blue shirt under a blue jacket.
The royal couple were in the North Yorkshire resort to engage with local organisations who will benefit from funding which has been created from a collaboration between The Royal Foundation of The Prince and Princess of Wales and the Two Ridings Community Foundation.
