Prince Harry may be reconnecting with his wild side if new photographs are anything to go by.
US gossip website TMZ.com has posted naked pictures purporting to be of of the 27-year-old royal during a weekend of partying in Las Vegas.
The prince allegedly bared all during a game of strip billiards with a room full of friends in his VIP suite after earlier meeting a group of women at a hotel bar, the website claims.
In one photo, he appears to be cupping his genitals while a topless woman stands behind him.
While the website quotes a spokesperson for the royal family offering "no comment", Twitter is alight with speculation over the photos' veracity.
@Scotty_McTweety tweeted: "To be honest, i'm calling fake on these particular photos, Harry is a rebel royal but he's not that daft....is he??", while @kickbozerlad added: "'A fully nude Harry cups his genitals while a seemingly topless woman stands behind him...' => surely fake?!"
While in Vegas, Prince Harry also challenged Olympic gold-medallist Ryan Lochte to a race during a pool party, according to UK media, echoing his antics five months ago, when he "beat" Jamaican sprinter Usain Bolt during an official tour.
The prince, who was reportedly wearing jeans and given a head start, reportedly lost to Lochte, however, in front of 5000 other guests.
It's not the first time Prince Harry has jumped fully-clothed into a swimming pool. He did it on a holiday in Croatia last year.
The prince was often caught partying drunk during his teenage years, but appeared to have put most of it behind him.
He has been taking more responsibility as a royal member, including being the official royal representative of the Monarch at the Olympics' closing ceremony.
