The couple, who have been dubbed the 'William and Kate of the Himalayas,' smiled to the crowds as the King cradled their baby son, who was born on February 19 this year. The pair had previously released photos of the heir to the throne but kept his name private.
The happy couple named their son Jigme Namgyel Wangchuck
Speaking to the people of Bhutan, King Jigme revealed that he and his wife Queen Jetsun had named their son Jigme Namgyel Wangchuck. The King said: "The Gyalsey is not just the prince of the King and Gyaltsuen, but a son to all the Bhutanese people... Jigme means fearless. It symbolizes great courage to overcome any challenge that he may confront in future as he serves our country."
He continued: "When the time comes for Gyalsey Jigme Namgyel Wangchuck to serve his country, he must always place the concerns of his country above all else and serve his people justly with great love and dedication. It will be his sacred responsibility to build a harmonious and just society, and thereby, fulfill all the aspirations of his people.
The 'William and Kate of the Himalayas' met the Duke and Duchess earlier this week
The two couples have much in common, as both were married in 2011, and Queen Jetsun was also not of royal origins before she wed, like Kate. The Queen is hugely popular with the people of Bhutan, particularly after she opted to go on a walking tour of Bhutan to meet the people instead of a honeymoon.
The education minister of Bhutan, Norbu Wangchuk, spoke about the relationship between the two royal couples after Prince William and Kate's visit earlier this week. He said: "I think our happiness index has shot up, this visit has been a blessing for Bhutan. It is wonderful they got to meet our King and Queen and the new prince.
"They're a marvellous couple and it's been an honour to receive them. The relationship between and King and Queen and the British people is a good one."
