Purported naked photos of partying Prince Harry surface in Las Vegas

 What happens in Vegas stays in Vegas -- unless you're Prince Harry and TMZ publishes pictures of you, or someone who looks very much like you, cavorting naked during a game of strip billiards.

The tabloid website posted the photos online Tuesday night, and said the royal romp took place four days earlier at a "high rollers hotel suite" on the Las Vegas strip.

One photo shows a redheaded man, who resembles Harry, stark naked but for a wristwatch and a necklace. The man's hands cup his genitals. His face is turned toward the television set in the suite. And his body partially shields that of another person, also naked.

The necklace the man has on appears to match one Prince Harry was seen wearing poolside in Vegas on Monday.

A second picture shows the same person hugging a woman from behind next to a pool table. Both are naked.

"Harry, along with a large entourage, went down to the hotel bar and met a bunch of hot chicks ... and invited them up to his VIP suite," said TMZ, which like CNN is a Time Warner company.

CNN left messages for Clarence House, the royal home in London, but did not hear back from the press office.

A representative for the royal family told TMZ, "We have no comment to make on the photos at this time."

The photos quickly circulated worldwide, providing plenty of fodder on Twitter.

"The Queen must be sooo proud that Prince Harry showed us his crown jewels!!!! Lol," said Danielle Monaro, part of the Elvis Duran And The Morning Show, a syndicated radio program.

"Prince William shows his cojones by rescuing stranded women in the ocean. Prince Harry shows his cojones by, well, showing his cojones," tweeted Jennifer Burke with Canada's CTV network.

Last week, William helped save a teenage girl who was in danger of drowning off the coast of Wales in his role as Royal Air Force search and rescue pilot.

The 16-year-old girl was caught in a rip current and rapidly losing strength when the rescue team was called out.

William, known to his RAF comrades as Flight Lt. Wales, has been stationed at a search-and-rescue base on the remote Welsh island of Anglesey since 2010, and lives there with Catherine, the Duchess of Cambridge.

His younger brother, 27-year-old Harry,
