When it comes to Prince Henry Charles Albert David of Wales aka “Prince Harry” … what happens in Vegas, ends up all over the Internet.

Last week, the royal prince not only compromised his seat on the throne, but also shamed his royal family, when TMZ got a hold of two photos showing the prince COMPLETELY NAKED — and hugged up with two equally naked women — following a friendly game of “strip billiards.”

TMZ, of course, posted the pics online, and they were shared and gawked at all over the world. For referential purposes, take a gander at them below:

Royal Officials were forced to confirm that the pictures were of Prince Harry, who, we later found out stupidly invited a large group of people up to his hotel suite without asking them to surrender their phones/cameras.

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.

TMZ spoke with several people in the Las Vegas VIP scene who tell us they see situations like this every day and it could have been easily contained, but as one source put it, “Harry’s team acted like a bunch of amateurs.”

But that’s not even the half of it.

Sources tell Radar Online that that Prince Harry’s “naked romp” in Las Vegas in his suite at the Wynn Hotel was all caught on video … which could definitely make this scandal even bigger than it already is.

“There is video of Harry partying naked with women in the Las Vegas hotel room,” a source familiar with the situation said. “There have been some very quiet inquiries to see how much the video is worth.

“If the video goes public this could be the biggest Royal scandal ever.” (The video was not offered to the outlet that bought the photographs, according to the source.)

“The video has not been shopped around yet, its existence is being kept as discreet as possible,” the source told Radar. “With all the attention the photos got, the people with the video know it could be worth a fortune.”

Apparently, the anonymous person who owns the video hasn’t showed it to anyone, and it isn’t known whether or not they’re the same person who also took the pictures.

But the big question is … will we ever actually get to see the video?

“There are many powerful people who don’t want this video to go public and that is one reason why the seller is being so discreet right now,” the source said. “This video could generate an enormous privacy lawsuit but it could also make the seller rich.”

The content shown on the video is far from tame, according to the source who says: “A lot went on in that hotel room that night, that much is for sure.”

Oh, but wait … it gets worse.

Someone who was actually at the Las Vegas “party” in Prince Harry’s hotel room is alleging that cocaine, among other drugs, was used in the hotel room.

“Things got pretty crazy in Prince Harry’s suite that night. Everyone was drinking and drugs were also being used by some people,” the eyewitness who was present at Harry’s party exclusively revealed to RadarOnline.com.

“Some people were snorting cocaine,” the eyewitness told RadarOnline.com exclusively. The eyewitness asked to remain anonymous due to the magnitude of the scandal.

The new information comes two days after a report in a Las Vegas paper said that the nude photos of the Party Prince’s wild weekend were merely the beginning of the scandal and that “something gigantic” had not yet been revealed.

The source at the party saw cocaine being used and also told Radar exclusively that a number of the guests were on drugs when they arrived at his suite.

“Some were already rolling on shrooms (hallucinogenic mushrooms) when they arrived at the party, and some were just high on weed. And that’s exactly why no one there has come forward on the record…they don’t want to be implicated for any illegal activities,” the source revealed to Radar.

The “source” made sure to mention that they didn’t actually see Prince Harry using cocaine or any other illegal drugs, but they also mentioned that they weren’t with the Prince — who is known to be a hardcore partier — the whole time.

Meanwhile, Prince Harry is reportedly back to his royal duties. According to E! News, the prince refuses to hide from the media, and plans on attending the WellChild Awards in London on Monday (Sep 3), as well as one single Paralympic swimming event.
