The scandal has only just begun for the British royal, who allegedly stars in footage taken at the Las Vegas party where he stripped naked during his holiday last week.
"There is video of Harry partying naked with women in the Las Vegas hotel room," a source told Radar Online. "There have been some very quiet inquiries to see how much the video is worth."
The footage wasn't offered when the original nude photos were sold to TMZ last week.
"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."
Meanwhile, another witness has come forward claiming that drugs were used at the party.
"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 told Radar.
"Some people were snorting cocaine … Some were already rolling on 'shrooms [hallucinogenic mushrooms] when they arrived at the party, and some were just high on weed."
The witness, who asked to remain anonymous, didn't see Harry use drugs.
The 27-year-old prince has been in hiding since his return to the UK several days ago but he won't be cancelling his upcoming appearance at the London Paralympics.
A royal spokesperson told TMZ, "The Duke and Duchess [Wills and Kate] and Prince Harry will attend select events during the Games, including goalball, cycling, swimming and Athletics."
The Games begin today and run until September 9. No doubt most cameras will be trained on the stands rather than the athletes now!
