Prince Harry hit Las Vegas just like one of the regular boys in his military unit, but what happened in Vegas isn’t staying in Vegas. The tabloids are already all over his night out.

While Europe teeters on the brink of a financial crisis that could send it back into a recession, Harry, 27, partied like it was 1999, staying out until 4 a.m.

An officer and supposedly a gentleman–he was recently promoted to captain–the randy lad began his first trip to Sin City at the Cirque du Soleil in the up-scale Bellagio hotel and casino.

The show is described as “aquatic tapestry of artistry, surrealism and theatrical romance.”

No whips and midgets here. The show features world-class acrobats, synchronized swimmers, divers and other characters, including mysterious featured performer “O.”

Harry, 27, was “all smiles” following the acrobatic performance,” according to People magazine.

From there, he took in the scene at Tryst, a nightclub at the Wynn Las Vegas hotel.

Mixed drinks are $15, beers are $10 and a bottle of bottom-shelf Captain Morgan is $465. Men pay a $30 cover to get in.

Numerous celebrities like rapper Lil’ Wayne and Taboo from the Black Eyed Peas have been spotted there.

Hordes of party girls–one patron described them as “trashy Paris Hilton types,” flock to the club, hoping to hook up with celebrities or high rollers.

Harry arrived around midnight a little under-dressed in a blue flannel shirt and light blue jeans and partied unnoticed until the the deejay blew his cover.

“Playin moonbahton for Prince Harry.. #onlyinvegas,” he Tweeted.

Harry was spotted getting friendly with a blonde (his type) on the dance floor and later was seen talking to a brunette.

After that, Harry and eight guy friends gambled the rest of the night away, according to reports.

He lost $300 gambling and his friends lost $200,” a source told People. “He couldn’t believe you got free
 drinks from gambling at the blackjack tables.”

Harry is undergoing advanced combat helicopter training, a grueling eight week pilot training course at Gila Bend Air Force Auxiliary Field in Arizona.

Harry spent 10 weeks in Afghanistan in late 2007 to early 2008, and is hoping to be redeployed as early as April 2012.
