The King and Queen of Bhutan, 10 Years
King Jigme Khear Namgyel Wangchuck, 40, and his wife Jetsun Pema, 29, met when she was just 7 years old. Though she doesn't have any royal connections by blood, her family does have lots of political connections to the royals. When they met, she innocently confessed her love for the prince, and they promised that if they were still single when they were older they would get married.
