Yep, he's a royal hottie.
If you thought Prince Harry was the heartthrob of the royal family, you would be sorely mistaken. Meet Arthur Chatto, the 18-year-old grandson of Queen Elizabeth II's sister, Princess Margaret.

Yep, this guy has royal genes (while wearing no jeans).
Arthur is 23rd in the line for the British throne, so it's not likely that this hottie will ever be the top dog in England, and that may be good news to the rest of us since he would never be allowed to post an underwear selfie otherwise.
The royal isn't always showing off his good looks and rock solid body on Instagram though (unfortunately). While he isn't hugely active on Instagram, he does share images of himself from time to time while taking part in his hobbies, which seem to include a lot of outdoor activities.
He often poses for model-esque images, as well.
British reports indicate that Arthur recently graduated from Eton College. The school, which is one of the most famous in the world, is featured in several of his 16 Instagram pics. Arthur reportedly graduated with a focus on military learning.
For all of us, we're learning that the royal blood line is looking really, really good these days.
