This Royal isn't as concerned with privacy as his famed cousins William and videos of parents having sexHenry, but being 23rd in the line to the throne probably gives him much more leeway.

Arthur Chatto -- son of Princess Margaret's daughter, Sarah Chatto -- has matured since his days as Queen Elizabeth's page boy and he has the selfie to prove it.

Sporting his Calvin's, the 18-year-old flexed his biceps in this shirtless selfie that he posted to Instagram and the internet was thirsty for it.

His followers descended upon the picture with heart eyes emojis and declarations of admiration.

(He doesn't say what the mark on his chest is.)

UPDATE: July 28, 2017, 8:50 a.m. BST It looks like Chatto didn’t anticipate all the attention he would get from his selfie, so he made his Instagram account private.

Chatto's rock hard physique can be attributed to his Combined Cadet Force training at Eton college -- a program that prepares students for military service. Prince Harry also trained in the CCF at Eton before signing on to the Armed Forces.

Unlike Harry, it's believed that Chatto will be attending university before his service, and is rumored to be enrolling at the University of Edinburgh.

Royal or not, Chatto is like every other typical teen who's living online and we're here for it.

Keep those selfies coming.
