Britain's Prince Harry partied hard in Las Vegas and tried harder to hide his modesty in a leaked naked photo.
The flame-haired royal was spotted at his best playboy image playing pool in a Las Vegas apartment with unidentified woman.
The picture was leaked in a celebrity website TMZ who claims that it is Prince Harry with a topless woman.
The naked photo show Prince Harry with a topless woman behind him.
In another photo the still unclothed royal gives another woman a hearty bear hug from behind.
Earlier on Sunday night Harry was spotted in the XS Nightclub in Las Vegas, the same place where the 28-year-old gold medal-winning swimmer, Ryan Lochte, was hanging out, and one reveller took to twitter to reveal the pair were having "the most fun ever".
One clubber wrote: "Wait...Prince Harry AND Ryan Lochte? This is just the most fun ever. #XS #Vegas. (sic)"
Along with the nude photo TMZ reports that Harry "went down to the hotel bar and met a bunch of hot chicks ... and invited them up to his VIP suite."
However, the man in the photos is wearing the same necklace as one Harry was spotted wearing earlier this week.
A source told E!: "It was his first Vegas pool party. He was with a group of around six to seven friends and just wanted to have fun with the boys. He was in town to take a break and have fun.
"He was letting loose, and swimming and dancing to the music. It was great to see him acting like any normal guy. Harry and his friends even had a blow up whale in their area, they were just fooling around and joking and having some drinks and just enjoying themselves."
Harry took in a number of events during the London 2012 Olympics and he is due to watch the Paralympics in London later this month.
Photos are genuine: Palace
The British royal family said Wednesday nude photographs of Prince Harry cavorting with friends on holiday in Las Vegas were genuine.
In one of the two photographs, the 27-year-old is pictured, apparently wearing only a watch and a necklace, covering his genitals with his hands while another person, who also appears to be nude, stands close behind him.
In the other, he is bent over bear-hugging a second person, who also appears to be naked. It is not clear if the person is a man or a woman.
Clarence House confirmed to AFP on Wednesday that the images were genuine.
"At this time we don't have a comment," a spokesman told AFP, adding: "We may do later."
It is rare for Clarence House to confirm the validity of such images, which raise questions about security surrounding the British royal.
The two images were taken at the Wynn Resort in Las Vegas after a game of strip billiards last weekend, according to TMZ.
Video has also been released from the same trip that purports to show the prince racing US Olympic swimming gold medallist Ryan Lochte in the pool of a nightclub in the hotel.
Lochte, who was in Las Vegas belatedly celebrating his 28th birthday, told Britain's Daily Mail newspaper that he was "surprised" Harry had challenged him to the race, which the swimming star won.
"He's a great guy, and it was a huge honour to meet him," Lochte was quoted as saying, adding: "I definitely wasn't going to take it easy on him!"
It is not the first time Harry has taken on one of the world's top sportsmen -- during a Caribbean tour in March, he managed to beat the world's fastest man Usain Bolt in a joke race.
Harry was in Las Vegas after hosting a charity event in San Diego.
Known for his playboy reputation, the prince has tried to distance himself from that lifestyle.
A trained army helicopter pilot, he has expressed a strong interest in returning to serve in Afghanistan. His first stint there had to be cut short in 2008 when a media blackout was breached.
