Prince Harry Vegas Pictures

The Royal Family is FURIOUS over the Prince Harry naked photo fiasco ... and the anger isn't directed solely at Harry -- we're told the family is also pointing the finger at the Prince's minders and personal security team.

Here's what we know. The night of the naked Vegas hotel party, Harry was hanging with two male friends ... after some boozing, the group decided to bring a bunch of chicks they had just met back to Harry's VIP suite at Encore.

That's when Harry's people dropped the ball.

When the girls entered the room, we're told the ladies were NOT asked to surrender their phones ... an epic failure considering Harry's well-documented wild side.

As the party fired up, several girls began to snap pics on their cell-phones ... and one of Harry's minders lackadaisically told the women, "awww, come on .. no photos."

Sources who were there tell TMZ ... the minders were asleep at the wheel, enjoying the party more than protecting the Prince from himself.

After more boozing, the clothes came off ... and more photos were taken, in plain view of the handlers, yet Harry's people did nothing.

Prince Harry clearly sucks at strip billiards -- but at least he had enough family pride (and jewels) to pay off his bet, and get naked when he lost. Not sure the Queen will see it that way, but ...

Prince Harry's package is so small ... he shouldn't be allowed to call himself a prince at all -- this according to British "Real Housewives of Beverly Hills" star Lisa Vanderpump.

Lisa was out in Beverly Hills earlier today when we asked if she's seen the pictures -- and she must have been living under a rock the last 12 hours ... because she hadn't.

So our camera guy showed them to her on his phone -- and Lisa replied, "I need a magnifying glass to see that! Hold on, let me get my glasses."

Once she got a good look, Lisa handed the phone back in disbelief, saying, "That's not a ROYAL penis!"

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.

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."

Prince Harry has just returned to the motherland, and he's got some serious 'splaining to do to one pissed off Queen.

Harry flew from Los Angeles to England last night, hours after TMZ posted pics of the prince buck naked during a strip billiards party in Vegas.

Passengers on the flight tell TMZ ... Harry did not mingle on board ... he stayed in the upstairs cabin of the 747.

Prince Harry wasn't in the mood to discuss the ball-cupping naked photos from Vegas this weekend -- quickly hopping into a black Escalade yesterday in L.A. ... and gunning it to the airport.

Harry was leaving a swank restaurant near Venice Beach when a photog asked if he had any comment about the photos -- big surprise ... Harry did not.

As we reported, Harry has already returned to the Motherland after TMZ posted photos of the royal going Cockney in a Vegas hotel room with a bunch of hot chicks Friday night.

Prince Harry was still jonesin for ladies following his naked hotel party in Vegas ... 'cause later that weekend, he was back at the pool scene flirtin' with a bunch of bikini babes.

Harry hit the Encore Beach Club at the Wynn Hotel on Sunday ... where he was playfully splashing around with one girl and high-fiving another ... while hanging in the pool with his buddies.

It's unclear if either of the women were in attendance at His Royal Highness' naked billiards tournament that went down in the Prince's VIP suite Friday night.
