Things could get a lot worse for Prince Harry - and the entire royal family - if video from his naked romp in Las Vegas sees the light of day.

And it just might, according to Radar Online, which reports that someone in the hotel room that night captured the prince's nude antics on video and is quietly shopping it around to buyers.

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

And the footage must be steamy, because the source added, "If the video goes public, this could be the biggest Royal scandal ever."

Photos posted to TMZ of a naked Harry covering his genitals with his hands and exposing his buttocks created an online firestorm, so video of the incident would likely drive even more traffic.

Reports say whoever took the video is hoping to sell it because it could be worth a fortune, but that person wants to remain anonymous for fear of officials who don't want it released.

"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."

But the source did guarantee one thing - the video is just as wild as viewers would hope.

"A lot went on in that hotel room that night, that much is for sure," the source said.
