Prince Harry put the crown jewels on display in Vegas this weekend ... getting BARE ASS NAKED during a game of strip billiards with a room full of friends in his VIP suite.
It all went down Friday night during a raging party in a high rollers hotel suite.
We're told Harry, along with a large entourage, went down to the hotel bar and met a bunch of hot chicks ... and invited them up to his VIP suite.
Once in the room, things got WILD ... with the group playing a game of strip pool that quickly escalated into full-on royal nudity.
Some of the partiers snapped photos of the madness. In one photo, a fully nude Harry cups his genitals while a seemingly topless woman stands behind him.
In another photo, a naked Harry is bear-hugging a woman who appears to be completely naked as well.
No word on who the women are ... or if they got Harry's phone number.
A rep for the Royal Family tells us, "We have no comment to make on the photos at this time." :lol:
