Jetsun Pema, 27, is the world's youngest living queen.
She took the throne at the age of 21 in 2011, when she married King Jigme Khesar Namgyel Wangchuck of Bhutan, now 37.
The couple — who have a 1-year-old son, Jigme Namgyel Wangchuck — have both studied in England, share a love of art, and were once dubbed the Will and Kate of The Himalayas.
Speaking about his wife, the king once told local reporters: "I have been waiting for quite some time to get married. But it doesn't matter when you get married as long as it is to the right person. I am certain I am married to the right person."
More than 50,000 Bhutanese citizens attended the final day of wedding celebrations at Changlimithang Stadium in Thimphu.
Their union has been described as a love marriage, with Pema portrayed as a "commoner by the secretariat. The Washington Post reported that "in one version of events, the two met at a picnic when she was 7 and he was 17; she reportedly came up to him and gave him a hug."
However, her family apparently has long-term links with the royals. She is the daughter of a pilot, but her paternal great-grandfather was lord of the eastern province of Tashigang, and her maternal grandfather was the half-brother of the wife of Bhutan's second king, according to The Post.
She's known for her charity work for organisations like the Bhutan Red Cross Society, Ability Bhutan Society, and Bhutan Kidney Association.
Despite her royal duties, she appears to be a hands-on mother.
She gave birth to the royal couple's first child, a son named Jigme Namgyel Wangchuck, in February 2016.
The king, who also appears to be an involved father, once told reporters: "I have been waiting for quite some time to get married. But it doesn't matter when you get married as long as it is to the right person. I am certain I am married to the right person."
"She is a wonderful human being, intelligent," he told reporters. "She and I share one big thing in common: a love and passion for art."
In April 2016, the king and queen welcomed the duke and duchess of Cambridge on a royal visit. The Bhutanese royals were once nicknamed the Will and Kate of the Himalayas.
They most recently visited New Delhi, India, in October, where their 1-year-old son reportedly melted hearts — and it's not hard to see why.
