Prince Harry partied with Ryan Lochte in Vegas this weekend, but he took some hot girls back to his hotel room with him at the MGM grand. The sexy bachelor had a large entourage with him and they were all partying in a high rollers hotel suite.

That's when things got R-rated. The group was playing a game of strip pool "that quickly escalated into full-on royal nudity."

Some folks at the party were sober enough to take some pretty good camera phone pics. Harry is seen cupping the royal jewels while a topless chick stands behind him and he appears to be hugging a naked girl in the second photo above. The royal family has not commented on the photos, but there's no doubt that the third heir to the throne has shamed the royal family with his drunken antics. Keep partying Harry! Don't stop coming to the States!
