A 32-year-old beautician, who says she was one of the woman who partied with Prince Harry in Las Vegas, told of having a 15 to 20-minute "drunken fumble" with the prince during which he was naked and she was wearing just a string bikini.

"He was a gentleman, but he was so wasted. The alcohol affected him," Carrie Reichert told People.co.uk.

The third in line to the throne has had some explaining to do after naked pictures of him playing strip billiards in a Las Vegas hotel suite emerged on US showbiz site TMZ.

In one picture he was naked while bear hugging a nude blonde girl. In another he was standing in front of a naked girl, using his hands to cover himself.

Reichert said one of Harry's entourage had approached her and asked if she wanted to join his party in the penthouse.

"They were just picking up really pretty girls, about 10 of us," people.co.uk quoted her saying.

Without being checked by security staff, Reichert and the group were taken upstairs to the VIP room where they found the party in full swing.

"Harry was already undressed. It was just crazy. He looked actually delirious. There was a pool table and he was playing air guitar with pool sticks," Reichert said.

"He was screaming out, 'Somebody get me a glove! I'm going to do a Michael Jackson impression!'

"He would just randomly walk up to you and hug you. He was just really friendly and there were just really random naked hugs. It was funny."

Some girls were naked and some of the men were half-dressed, Reichert said.

She insists it wasn't an orgy but Harry was encouraging his guests to strip off.

"He was pressing his body up against the window and saying 'Look at me Vegas!' because he's got this huge window and of course you can see all of Vegas down the strip," she said.

"Just pressing up against the window just like, 'Look at me Vegas, these are the royal jewels'."

She had talked to Harry about England, where she was born while her father, a US serviceman, was stationed there.

Then Harry took Reichert's hand and led her towards his bedroom while the other guests partied in the living room.

"There was not very much talking at that time, his clothes were off. I had a bikini on. A string bikini. I had a party dress over that, and that came off. And I just had a bikini."

She and Harry then had what she describes as a "drunken fumble".

Reichert added: "We kissed for 15 to 20 minutes. I am sure somebody stumbled in as there were people going in and out of rooms all the time.

"We kissed again and he said 'That was great'. "He told me I was beautiful and gorgeous, which was sweet. Then we kind of nonchalantly returned to the party and kept drinking," she said.

"It wasn't romantic, just fun."
