The Middleton family lived in Jordan for a few years in the ’80s and they relocated after Kate’s father was asked to move for work.
The image of the family at the ruins surfaced just before the duchess married Prince William in 2011.
When he saw the photo at the ruins, the Duke of Cambridge told the Jordanian Prince Al-Hussein bin Abdullad II, who was taking him on a tour, 'Michael’s looking very smart in his flip-flops.'
William added, 'I would love to bring the kids next time.'
The royal also said that his wife had 'loved' living in Jordan as a child.
'She loved it here, she really did. She is very upset that I am coming here without her.'
Unfortunately, Kate is currently on maternity leave from royal duties following the birth of their youngest son Prince Louis.
