Paris Hilton did what she does best, and partied up a storm in Las Vegas with new beau DJ Afrojack.

The heiress was like a love sick teenager as she danced by the sidelines at Surrender Nightclub at Encore Las Vegas while watching the Grammy winning producer spin the decks and frequently reached out to touch him.

Her appearance at the Sin City venue comes more than a year after she was banned from stepping foot in the Wynn and Encore resorts following her cocaine bust with ex-boyfriend Cy Waits.

Cy was terminated from his duties at the hotels' clubs and Paris was asked not to return after they were pulled over while in their car when police smelled marijuana wafting through the window.

The cops found cocaine in her purse and she eventually pleaded guilty to two misdemeanor charges and the socialite was sentenced to one year probation and 200 hours of community service and ordered to complete a drug abuse program.

Paris and Cy ended their relationship in June and the 30-year-old has recently been spotted around the globe with Dutch-born Afrojack, real name Nick Van de Wall.

She arrived at 12.45 and downed Grey Goose cocktails and danced into the early hours. The twosome have been seen a lot together recently and were seen spending some quality time together in Hawaii back in November and he attended the Christmas Party at her home earlier this month.

Prince Harry has continued his tour of fun in "The States" and last night the party landed in Las Vegas.

The British royal is in the U.S. as part of his military training but as hard as he has worked, Harry has also made time for lots of play.

The 27-year-old enjoyed his first visit to Sin City and blended into the crowd at the Wynn Las Vegas' Tryst Nightclub where he stayed for a couple of hours, RadarOnline.com has confirmed.

Harry was ushered to a VIP table around midnight and quickly got the attention of a pretty blonde, who he danced with suggestively.

The frisky fun-loving royal, who is third in line to the throne, was also spotted jumping into the lap of one of his security guards and falling to the floor laughing when he dropped off.

It was 3 am before Captain Wales, as he’s known in the army, retired to his suite in the Wynn.

Before hitting up Sin City, Harry’s had a flirty night in San Diego, and fun dinner outing in Arizona where he scoffed down a whole pizza on his own.

The Las Vegas adventure is a traditional break in the middle of the intense helicopter training course the pilot prince is taking.

Paris Hilton’s cocaine possession bust outside the Wynn in Las Vegas just got her banned from the swanky resort.

RadarOnline.com has confirmed Hilton’s ban from the two Wynn resorts – Wynn Las Vegas and Encore – through a rep for Wynn Resorts Ltd. on Wednesday.

The socialite was arrested early Saturday morning in Las Vegas after cops found 0.8 grams of cocaine on the heiress following a traffic stop when an officer smelled “the strong odor of marijuana coming from the vehicle.”

Hilton’s boyfriend Cy Waits was driving the vehicle and was arrested on DUI after authorities “administered a series of field sobriety tests, which Waits failed.”

As RadarOnline.com previously reported, Waits was let go from his job at the Wynn Resort following his arrest.

“Cy Waits has been separated from the company and is free to pursue other interests,” the Wynn Resort said in a statement.

What’s an heiress to do with all her free time? Not cocaine, says her hair stylist.

Paris Hilton’s hair stylist Michael Boychuck tells RadarOnline.com exclusively that Hilton “wants everyone to know she does not do drugs and does not have time for that.”

Paris Hilton is about to discover what O.J. Simpson already knows: when it comes to justice, Las Vegas can be a lot tougher than Los Angeles.

District Attorney David Roger is highly unlikely to offer Paris a plea bargain deal on her cocaine possession charge, a source close to the case told RadarOnline.com exclusively.

The veteran Clark County, Nevada prosecutor put Simpson behind bars on robbery charges after the former football great beat murder charges in Los Angeles.

“Roger won't tolerate celebrities coming to Las Vegas and thinking they can get away with illegal behavior,” the source close to the case told RadarOnline.com.

“It's going to be extremely difficult for Paris to get out of these charges, even with the brilliant legal skills of her lawyer, David Chesnoff.”

Hilton is facing a felony drug possession charge that carries a prison sentence of one to four years. She claimed the purse she was carrying, where the cocaine was found, did not belong to her.

Roger is running for reelection and has a record of high-profile victories in the legal arena.

“This is a high profile case, right before a very important election, and it's very likely that there will be no plea bargaining down of these charges," said the source.

According to an arrest report obtained by RadarOnline.com, Hilton, 29, told cops she didn’t own the purse in which 0.8 grams of cocaine was found, but admitted she owned other items that were in the purse.

OFFICIAL DOCUMENT: Read The Complaint

She reportedly told a Las Vegas police lieutenant that she had borrowed the purse from a friend, but acknowledged owning money, credit cards and a broken tablet of the prescription drug Albuterol that was also found in the bag.

The man who arrested Hilton, Lt. Dennis Flynn, said a small plastic "bindle" of the drug fell out of her purse when she reached for a tube of lip balm.

Hilton is taking the charges "very seriously,” said a source close to the socialite.

“Paris has been advised to lay low,” said the friend.

“Paris is 100 per cent adamant that the cocaine found in the purse, wasn’t hers.

“She says she borrowed the handbag from a girlfriend because the handbag she was going to use for the night didn't match her outfit.”

Hilton's boyfriend, 34-year-old Las Vegas nightclub mogul Cy Waits, was also arrested.

Police say Waits failed field sobriety tests after he was stopped while driving the black Cadillac Escalade from which a police motorcycle officer reported smelling marijuana smoke.

The Vegas bust was the third encounter in three months with law enforcement for Hilton.

Paris Hilton has another set of eyes and ears that witnessed Vegas cops searching her handbag and placing her under arrest inside the security office at the Wynn Las Vegas, RadarOnline.com has learned exclusively. The Wynn security cameras caught the whole thing!

As RadarOnline.com was the first to report, Paris was not arrested in the car with her boyfriend Cy Waits after being pulled over by cops who smelled marijuana.  Instead, Paris was taken into the Wynn's security office where -- as the Las Vegas Metro police put it -- "it was discovered that Ms. Hilton had cocaine in her possession."  Only then was she arrested.

Now RadarOnline.com has confirmed that the entire incident was captured by Wynn's security cameras, and it could be good news for Paris.

A source close to the situation tells us, "the search of Paris and arrest was all captured on tape, which could help her tremendously.  Her lawyer David Chesnoff is going to claim it was an illegal search, in part because she was taken away from the scene to this other location.  Chesnoff will also be able to take apart every single thing that happened during the search and arrest because he'll have the video to work off of.  Furthermore, Paris repeatedly said while she was being detained that the purse wasn't hers.

Chesnoff is going to get the tape and use it to bolster his contention that the search was illegal," the source says.

Friday night's arrest of Paris Hilton on suspicion of cocaine possession may have been a law-breaker in itself, a source close to the heiress tells RadarOnline.com exclusively.

PHOTOS: Celebrity Mugshots

Las Vegas PD officers pulled over a black Cadillac Escalade in front of the Wynn Las Vegas Friday night because they suspected pot was being smoked in the vehicle. The driver was Paris's nightclub mogul boyfriend Cy Waits, who was arrested for suspicion of driving under the influence of drugs.

PHOTOS: Celebs Who Have Made Sex Tapes

But Paris was not searched on the scene, the source tells RadarOnline.com exclusively, and that's where the case against Hilton may start to unravel.

PHOTOS: Celebs Who Have Done Jail Time

Paris was taken into the security offices at the Wynn and searched there, the source says. "Cops discovered the cocaine inside the security offices where Paris was taken. Because Paris was taken away from the scene where the car was pulled over, this could potentially be an illegal search of a person.

"Las Vegas Metro didn't follow standard procedures when Paris was arrested and her lawyer will be talking to the D.A. about this."

Paris is also insisting that the cocaine found in the purse wasn't hers -- because the purse itself wasn't hers!

PHOTOS: Celebs Who Have Perfumes

"Paris says she changed the purse she was carrying at the last minute last night because the one she had didn't coordinate with the rest of her outfit the way she wanted. She says she borrowed a friend's purse because it matched better."

The implication, of course, is that the cocaine belonged to Paris' friend and so she shouldn't be charged for it.

Paris' high-powered Vegas attorney David Chesnoff plans on talking to the Las Vegas D.A. Monday morning and lay out his case, mainly that there is no basis to charge his client because, the amount of cocaine was, "negligible, the purse it was found in wasn't hers, and Paris was illegally searched," the insider says.

Vegas Metro is issuing a press release on the bust later Saturday.
