Prince Charles and the Duchess of Cornwall welcomed the couple to Clarence House, and the heir to the throne took them to an event in Shoreditch for his Foundation for the Built Environment.
Since her wedding, Queen Jetsun has emerged as one of the new style icons of the Orient – an ambassador for the local designs of her tiny Himalayan state.
This week there was a chance for royal fans to see a more 'mainstream' side to her style, however.
The pretty 21-year-old royal looked smart and chic in a monochrome pencil skirt and black and grey blazer – accessorised with patent pumps and a Chanel bag.
King Jigme Khesar Namgyel Wangchuck also forwent traditional dress, wearing a grey suit. There was a splash of colour, however, in his bright tie.
The British stop is just the latest on the couple's world tour. They've already visited Japan and India.
