The Duke and Duchess of Cambridge, née Kate Middleton, will make their first official visit to Bhutan in the spring. During the tour of the remote mountain kingdom, the couple will meet the "William and Kate of the Himalayas" – King Jigme Khesar Namgyel Wanghuck and his wife, Queen Jetsun Pema.
Their trip to the Land of the Thunder Dragon will fall around the time that Queen Jetsun, 25, gives birth to her first child, a son.
Oxford graduate King Jigme, known as the "Dragon King" married his beautiful bride in a colourful three-day ceremony in the ancient capital of Punakha, seven months after William and Kate's wedding, at which he was a guest.
The young couple are seen as the modern face of Bhutan, which remained isolated from the outside world until the 1970s and only introduced TV in 1999.
Their five-hour marriage service in a Buddhist monastic fortress was broadcast live to the population of 750,000 and six months later the newlyweds visited the U.K., meeting Prince Charles and the Duchess of Cornwall at Clarence House.
In Bhutan, where tradition forbids public displays of affection, they have sparked a trend for couples to hold hands.
Jigme announced Jetsun's pregnancy on Facebook in November in a message to mark his father's 60th birthday, six years after his abdication.
He wrote, " I am deeply pleased to announce that Jetsun and I look forward to the birth of our son in the coming Losar (new year). We are overjoyed to offer this news as a gift on His Majesty's birth anniversary."
William and Kate, now parents to Prince George, 2, and eight-month-old Princess Charlotte, will no doubt have lots to discuss with their hosts.
They may also find enlightenment on an issue close to their hearts – mental health.
The Buddhist country measures wealth in terms of Gross National Happiness, instead of Gross National Product.
Conservationist William will also be intrigued by Bhutan's pristine forests and snow-capped peaks, which are home to some of the world’s most endangered species including the Bengal tiger, snow leopard, clouded leopard and pangolin.
Like Kate, Jetsun is considered a fashion icon because of her striking wardrobe of traditional clothing.
A pilot's daughter, she studied international relations, psychology and art history at Regents' College in London and now supports causes involving children and the environment.
