Prince William turned heads with a major switch-up of his appearance on Monday as he took to Instagram alongside his wife the Princess of Wales to congratulate Team GB for their success in the Paris Olympics.
It took royal fans mere seconds to notice the unmissable change in Prince William - that the historically cleanly-shaven royal was sporting a beard for a rugged edge.
It has been many years since the royal father of three has rocked facial hair in public, but he is not the first Prince of Wales to do so. In fact, it may well be that Kate's husband was inspired by a bearded moment his father King Charles indulged in in his earlier years - and the likeness is uncanny!

A 'naval beard' as it has become known, stems from the type of facial hair which is permitted in the Royal Navy - a full beard and mustache which join together and cover the jawline. Charles qualified as a helicopter pilot in 1974 before joining 845 Naval Air Squadron. He left the Navy in December 1976.

Charles was spotted later that day, having earlier ridden on horseback, in a smart double-breasted coat which suited his new appearance.

The Duke of Sussex also revealed William's thoughts on his beard. "Ah—there it was," Harry penned. "After he's come back from an assignment with Special Forces, Willy was sporting a full beard, and someone told him to be a good boy, run along, and shave it. He hated the idea of me enjoying a perk he'd been denied."
