Aside from nudity and alcohol, Prince Harry's Las Vegas party might have included something extra.

Naked photos of Harry playing "strip billards" at the Wynn Hotel and Casino surfaced last week to the dismay of his Royal Family.

However, a fellow partier told RadarOnline that cocaine and other drug use was involved in the scandal.

"Things got pretty crazy in Prince Harry's suite that night. Everyone was drinking and drugs were also being used by some people," the source told RadarOnline.

"Some people were snorting cocaine."

Not only did the partygoer see cocaine being used, but the source also said a number of guests were on drugs when they arrived at Harry's 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 did not see Prince Harry use cocaine or any other illegal drugs, but was not with Harry throughout the entire party.  

On Aug. 28, a different source told RadarOnline that Harry's antics were caught on video. Allegedly the video has been shopped around to a very limited number of people because the person with it is extremely nervous.

"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."

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

Whatever is in the video can't be good for the Royal Family's image. The source said "many powerful people" don't want the video to be leaked to the public.

"If the video goes public this could be the biggest Royal scandal ever."
