Bieber vs. Prince Harry WHO'D YOU RATHER?

It's a stripped down battle of the buns!

Here's Justin Bieber (19) live and unclothed during a Thanksgiving serenade to his grandma (left) ... and Harry the Prince of Wales (28) wearing nothing but the family jewels during a naked billiards party in Vegas (right).

Question is...

Mayor of Las Vegas to Prince Harry: COME BACK!

The Mayor of Las Vegas is making a serious plea to Prince Harry now that he's back from Afghanistan -- COME BACK TO VEGAS, ASAP!!!

Harry completed his 5-month military stint in the Middle East this week ... and once he got out of the war zone, he finally broke his silence about his Sin City naked photo scandal to the U.K. media ... saying, "I probably let myself down."

But TMZ spoke with Mayor Carolyn G. Goodman ... who thinks Harry deserves a Vegas do-over ... and tells us the city is ready to roll out the red carpet for His Royal Highness when he's ready to come back.

"We’re absolutely excited he’s home," Goodman says ... adding, "Prince Harry is always welcome in Las Vegas. When he was here everyone was talking about it. We welcome him back with open arms.”

It's no surprise ... considering the city reportedly enjoyed $23 million in free publicity that was generated by the naked billiards scandal.

Prince Harry on Nude Vegas Pics 'I Probably Let Myself Down'

It took 5 months, but Prince Harry is finally talking about his infamous game of strip billiards during his Las Vegas party weekend ... telling the media, "I probably let myself down."

Harry spoke with U.K. reporters after completing a 5-month military stint in Afghanistan -- and that's when someone asked about the pics ... first published on

"I probably let myself down," Harry said ... adding, "I let my family down, I let other people down."

He continued ... "At the end of the day, I was in a private area and there should be a certain amount of privacy ... The way I was treated ... I don't think is acceptable."

"Back home all my close friends rallied round me and were great."

Harry said he considers the incident a "classic example of me probably being too much army and not enough prince".

We broke the story ... Harry had invited a bunch of random women he met at a hotel bar up to his VIP suite for a party back in August ... and during the shindig he stripped down to his birthday suit after losing a game of strip billiards.

Prince Harry Naked Scandal GREAT for Vegas

Prince Harry's penis is being hailed as a HERO by Vegas officials ... 'cause experts say the free worldwide publicity Sin City enjoyed from the naked billiards scandal is worth roughly $23 MILLION.

The Las Vegas Convention and Visitors Authority issued a report, in which it says the pictures of Harry romping around his hotel room with a hot naked lady has reached an estimated 154 MILLION PEOPLE worldwide since TMZ broke the story back in August.

The agency says it's unable to track how much tourism has been generated due to the publicity ... but LVCVA Board Chairman Tom Collins is clearly optimistic ... saying at a recent board meeting, "God bless Prince Harry. He made us a bunch of money."

FYI -- The LVCVA had launched an advertising campaign for the city earlier in the summer warning tourists to "know the code" ... what happens in Vegas stays in Vegas.

When someone broke the code and shared the pics of the naked Prince, some officials felt the timing couldn't have been better.

Attempts to reach the Prince were unsuccessful ... 'cause he's fighting in the Middle East.

Prince Harry Royal Palace Won't Sue Sun Over Naked Pics

The Royals apparently believe Prince Harry has a place in The Sun, because they've decided not to take legal action against the U.K. tabloid for publishing Harry's naked pics.

The Royals have concluded, "We remain of the opinion that a hotel room is a private space where its occupants would have a reasonable expectation of privacy. Prince Harry is currently focused entirely on his deployment in Afghanistan, so to pursue a complaint relating to his private life would not be appropriate at this time and would prove to be a distraction."

The Royals tried to put the kibosh on the pics -- obtained by TMZ -- which were taken in the hotel room where a number of people were partying with the Prince.

Kate Middleton's Cousin I Can Get Naked Like Prince Harry Too!

Kate Middleton's second cousin once (clothing) removed Katrina Darling is following in Prince Harry's X-rated footsteps and getting naked for the camera too.

Katrina -- who as of earlier this year hadn't ever met the Duchess of Cambridge -- was barely dressed as the Statue of Liberty and once again brought her risque burlesque performance to a NYC club on Wednesday.

William and Kate have even more in common than they realized.

Prince Harry Resurfaces

Going out in public for the first time since TMZ published nude photos of him in Las Vegas, a clothed Prince Harry showed up today to the WellChild Awards ... which are being held at the InterContinental Hotel in London.

The event is held annually and honors the lives of the young people and the doctors and nurses who care for them.

As TMZ first reported, Prince Harry vowed he would appear at some point during this week's 2012 Paralympic Games in London, though it was unclear which event he would show up to first.

Prince Harry I Refuse to Hide Anymore

Prince Harry is adamant ... he WILL attend the 2012 Paralympic Games in London ... refusing to back out of his first scheduled appearance following the naked photo scandal.

Harry has been M.I.A. since returning to London from his X-rated Vegas weekend ... and there were rumors he would be cancelling all of his appearances and staying out of the spotlight until the whole thing blows over.

But TMZ spoke with a rep for the Royal Family who tells us ... "The Duke and Duchess [of Cambridge] and Prince Harry will attend select events during the Games, including goalball, cycling, swimming and Athletics.”

The Games are scheduled to begin tomorrow and will run through September 9. The rep was not clear about when Harry will show up.

Stay tuned ...

Rupert Murdoch Leave Prince Harry Alone!

Rupert Murdoch's got Prince Harry's naked back ... telling the world to give the young royal a break over his recent Vegas scandal -- not surprising, since Murdoch defied the Royals by publishing the pics.

Murdoch tweeted Saturday night, "Prince Harry. Give him a break. He may be on the public payroll one way or another, but the public loves him, even to enjoy Las Vegas."

TMZ broke the story ... the prince was photographed bare-ass playing billiards in Las Vegas this week and the photos quickly made the rounds all over the world. But the Royal Family was none too happy and pressured/banned British media outlet from publishing the pics.

Enter "The Sun" -- one of Murdoch's many media companies -- which published the nudie pics anyways.

Well played.

Prince Harry Throbbing Questions Linger

You might have heard we posted a few pics of Prince Harry the other day which kinda made the rounds. So we gotta ask ...

Prince Harry Offered $10 MILLION To Bone on Film

You knew it was coming ... and now, so does Prince Harry -- a multi-million dollar offer to get down and dirty in a XXX movie ... courtesy of the biggest porn studio on the planet.

Vivid Entertainment honcho Steve Hirsch just fired off a letter to the royal palace in London -- offering Prince Harry $10 million to star in a big budget adult film called "The Trouble with Harry" ... thanks to his recent naked romp in Vegas.

According to the letter, the film would also star "little Harry" and would feature some REAL royal carousing -- in the form of full-on boning.

Hirsch writes, "We assure you the sex will be well-scripted, and the crown jewels will not be 'minimized' in any way."

God save the peen.

Prince Harry PHOTO PARANOIA After Naked Romp

Prince Harry realized he made a huge mistake by allowing girls with cameras into his Vegas hotel room Friday night -- because just two days later in Sin City ... he was INCREDIBLY camera shy, refusing to pose for any pics with fans.

TMZ spoke with one of the girls Harry was hanging out with at a pool party Sunday night -- two days after the naked pics were taken -- and when she asked him to pose with her and her friends, Harry politely refused, saying. "No photos please."

It's a big shift in behavior from Friday -- when Harry invited several strange girls into his Vegas suite, and stripped naked in front of their cameras.

It didn't end there either, Harry happily goofed around at Wet Republic the next day -- probably the most photographed pool party in town.

But by Sunday night, Harry had grown tired of all the cameras.

As for his security ... our source says Harry was SURROUNDED -- in fact, she noticed at least 10 handlers around the pool. According to her, one of the security guards was even in the water with a waterproof cell phone (for aquatic emergencies).

But photos or no photos -- our girl says Harry was really flirty ... saying he was glad she made it to the pool party, and nodding to her bikini.

Harry, you dog.

Prince Harry's Naked Hotel Suite -- Inside the Ball Room!

Grab your stick ... with both hands ... 'cause it's time for a full tour of the Las Vegas hotel suite where Prince Harry ran around naked ... starting with the billiards room!!

TMZ has obtained pics of the VIP room at Wynn's Encore Tower Suites just like the one Harry stayed in when he ran around naked with a bunch of chicks this past weekend. According to the Wynn website, the suite is a two-story, 5,829-square foot duplex with 3 master bedrooms.

Each bathroom features a steam shower, whirlpool deep-soak tub, His and Hers sinks, separate water closet and bidet.

So how much does a room like this cost?? A rep for the hotel tells us it generally runs $6,000 per night during the week ... and $8,000 per night on the weekends.

Just make sure you wipe down the pool table before you play.

Prince Harry Chippendales Wants Piece of Royal Stripper Action

Prince Harry can now get naked in Vegas and actually get paid for it ... 'cause the people at Chippendales were so impressed with the nakie pics, they've officially offered him a job.

A rep for the bowtie bunch tells TMZ ... "Chippendales at the Rio All-Suite Hotel and Casino are reaching out to the royalty to gauge his interest in being our next guest host."

"We figured that since he seems to enjoy taking his clothes off in Las Vegas, why not do it on stage at the #1 Male Revue in the World."

If (and when) he accepts the offer, Harry would follow in the half-naked footsteps of 98 Degrees singer Jeff Timmons, Joey Lawrence and Ronnie from "Jersey Shore."

Please, no cameras.
