The King of Cambodia is unmarried, has no children, and is a dance instructor!

Norodom Sihamoni has been the King of Cambodia since October 2004. However, Norodom has a very interesting past compared to other Kings.

Before ascending to the throne of Cambodia Norodom Sihamoni was known for his work as a cultural ambassador and as a classical dance instructor.

If it is any consolidation, the King of Cambodia is more or less a figurehead much like the Queen of England. Unlike the Queen of England, Norodom Sihamoni has no children and has remained unmarried for the duration of his 60 year life.

According to his father, Norodom Sihanouk, Sihamoni "loves women as his sisters". It's up to you to decide whether or not that is really sweet, or a little weird.
