Hot Vegas

Getting trumped by Trump is nothing compared to the guy in Nevada who can now say he's juiced up the Juice -- and lived to tell the tale.

O.J. Simpson hit up a Nekter Juice Bar bright and early Friday in Summerlin, near where he's been holed up since getting out of prison last month. We're told Simpson ordered a Berry Banana Burst.

It's technically a smoothie made with strawberries, bananas, blueberries, cashew milk and a little agave nectar. All that for $6, and we're told he paid straight cash, homie!

Sylvester Stallone is vehemently denying an allegation he sexually assaulted a 16-year-old girl back in 1986 while he was in Las Vegas.

The claim is based on a police report in which the alleged victim said Stallone, who was 40 at the time, invited her up to his room at the Las Vegas Hilton. She claims he had sex with her, and then asked if she'd ever had sex with 2 men at the same time.

According to the police report, published by the Daily Mail, the girl claimed Stallone's bodyguard then came out of the bathroom and she was forced to perform oral sex on him and Stallone. She claims Stallone threatened to "beat her head in" if she told anyone.

Stallone's spokeswoman Michelle Bega tells TMZ ... "This is a ridiculous, categorically false story. No one was ever aware of this story until it was published today, including Mr. Stallone. At no time was Mr. Stallone ever contacted by authorities or anyone else regarding this matter."

The girl did not want to press charges because she was scared and humiliated, and reportedly signed a "no prosecution" form.

It's not uncommon, especially with a minor involved, for police and prosecutors to pursue a case without an alleged victim's cooperation. However, Las Vegas PD tells us they could not go forward in this type of case when the victim is refusing to cooperate and move forward with charges.

Stallone's rep is adamant ... "It never happened."

O.J. Simpson was booted from the Cosmopolitan Hotel in Las Vegas Wednesday night after allegedly getting wasted and then being extremely unruly.

Simpson had been frequenting bars at the hotel since his release from prison. Hotel staff tells TMZ ... at around midnight last night, Simpson was drunk and became disruptive at the Clique bar. We're told Simpson was angry at hotel staff and glasses broke at the bar.

Check out the pic below of Simpson strolling through the hotel Wednesday night.

Here's Celine Dion singing "My Heart Will Go On" one more time, but this time it's got a sick beat that got Celine up and dancing like you've never seen before.

The beat is courtesy of Steve Aoki, who joined Celine onstage for a Las Vegas benefit show Tuesday night at Omnia Nightclub. The 2 Vegas legends teamed up for this awesome performance -- Celine singing her "Titanic" hit, and Steve tacking on a remix you really gotta see.

Somebody hand Celine some glow sticks!

Seriously though, it was all for a great cause. The event raised $1 million for the Las Vegas Victims' Fund ... and also featured Kaskade, Lil Jon, Tiesto and Zedd.

But none of them had CD's ummm ... unique dance moves.

The tragic Vegas shooting has traumatized everyone, including the folks who work at Mandalay Bay, and the guy who runs it is asking guests to give some emotional support to his staff.

President and COO Chuck Bowling penned a letter that every guest will find on their pillow, which reads in part, "If you see an employee at one of our resorts, ask how they are doing, offer words of encouragement."

The note also says there will be a new wrap on the building -- the same side where the Vegas shooter unleashed his fury -- with the words, #VegasStrong.

Bowling says in his letter, "Las Vegas has always been a place for you to come for business, for a getaway, for a break, a reunion, a party, a laugh, a good time. While that is harder for us all right now, please know our incredible team of employees is here for anything you need."

Sources connected to Wanya tell us he isn't the one who invited O.J. to the shoot -- instead it was a friend of his, who also owns the home where it all went down.

We're told Wanya was at the shoot, briefly, but didn't interact with Simpson.

Forget O.J. Simpson's Heisman pose ... LOOK AT THIS!!!

The Juice was smack in the middle of a double dose of insanely hot chicks Wednesday in Las Vegas. The women were there for a commercial shoot ... the one on the right is Laura Saucedo, and she was so thrilled with the O.J. run-in, she posted pics and video.

We're told the crib used for the commercial is owned by Boyz II Men member Wanya Morris, who invited O.J. over for the day to hang. As for the commercial ... it was for a laser hair removal company -- L.A. Laser Hair Removal LV -- owned by Morris' longtime friend.

Simpson was NOT officially a part of the commercial, but he did get in a couple shots ... unclear if he'll make the final cut.

He's never met a camera he didn't love, though.

The Las Vegas shooter's 32nd-floor suite at Mandalay Bay is still completely shut off to the public, and in fact ... the whole floor's on lockdown.

One of our guys hit up the hotel Friday to check out the situation with Stephen Paddock's room after reports the hotel planned to never rent it out again. This video shows you can't even get close to the suite.

Elevators won't allow guests to get off on the 32nd floor, and security guards are stationed in stairwells to block access.

Law enforcement sources tell us Vegas PD completed the investigation of the suite, and they've turned it back over to the resort -- but it's clear Mandalay Bay's not ready to let morbid sightseers gawk at it.

Imagine Dragons' lead singer Dan Reynolds delivered a strong message of anti-terror in the aftermath of the mass shooting in Las Vegas ... their hometown.

The band performed Wednesday night in Chicago, and Dan paused to tell the crowd their tour has taken on a new meaning after the tragedy. He gave big props to all the fans who continue coming out to their concerts, and defiantly denounced all forms of terrorism.

He also reassured fans they would take every precaution to keep them safe.

Floyd Mayweather is telling his TMT bodyguards he's 100% retired -- and will NOT set up a rematch with Conor McGregor ... so says Floyd's hired muscle.

Of course, Floyd JUST posted footage from his boxing gym hitting the heavy bag -- and he looks pretty good. Plus, with all the money he made from the last fight, ya gotta wonder if he's thinking about a 51st fight.

So, when we saw Floyd's famous private security team, The Brixx Brothers -- Big G and Jizzy Mack -- we asked for the inside stuff with Mayweather's fight plan. They didn't exactly rule out a comeback.

BONUS -- With O.J. Simpson living just miles from Floyd's home in Vegas, we asked if Juice should look into private security too.

Jesus Campos, the Mandalay Bay security guard who alerted police to the Las Vegas shooter, is speaking out for the first time about the violent encounter that left him with gunshot wounds.

Jesus opened up to Ellen DeGeneres ... detailing the harrowing moments leading up to him discovering Stephen Paddock on the 32nd floor, just as he was starting to open fire on the crowd of concertgoers below.

He thinks a loud slamming door during his routine check of the floor is what tipped off his location to Paddock, who then started shooting into the hallway -- and hit Campos in the leg.

This incredibly intense video shows Dan Bilzerian frantically searching inside a police truck Sunday night as terrified concertgoers ducked for cover from the hail of bullets.

Dan -- the gun enthusiast getting roasted on social media for running away from the massacre -- is seen in this video running with a panicked group and hiding behind an unmanned Las Vegas Metro PD truck ... in the shadow of Mandalay Bay.

The video's intense -- some people are covered in blood, while others angrily debate whether to remain hiding there or make a run for it. Dan seemed adamant about taking matters into his own hands ... as he rummaged through the police unit, clearly looking for a firearm.

It's unclear if the vid was recorded before or after Bilzerian begged a cop for a gun.

Stephen Paddock had his sights set on Lollapalooza in Chicago and even booked 2 rooms in a hotel that overlooked the massive outdoor venue ... TMZ has learned.

Check out this pic of a computer screen at the Blackstone Hotel in Chicago, located across the street from the venue, Grant Park, where 400,000 people -- including Malia Obama -- squeezed in over 4 days to watch big musical acts.

Paddock booked one room for August 1, 2017, 2 days before the August 3 kickoff. Paddock then booked a second room for an August 3 arrival. Both rooms had an August 6 checkout ... that's when Lollapalooza ended.

The hotel directly overlooked the main stage as well as several adjoining stages. It also overlooks the main entrance and exit where thousands of people file through. And the hotel had a bird's-eye view of the crowd. We're told Paddock specifically requested both rooms be a "view room" which only face Grant Park, where the concert was being held. And here's the scariest part ... it's difficult if not impossible to flee because of Lake Michigan. Sources tell TMZ Paddock had never booked a room at the hotel before, nor had his girlfriend.

Our sources say Paddock never showed.

Celine Dion fought back tears as she returned to Las Vegas to do her show ... just 2 days after the carnage on the Las Vegas Strip.

The singer offered concertgoers at Caesars Palace Tuesday night words of comfort, while admitting it was a difficult decision about whether to even go on with the show.

Then she made an emotional announcement about how she, and her fans, will assist the families of the victims from Sunday's shooting that killed 59 people and injured more than 500.

Stephen Paddock's girlfriend -- a person of interest in the Vegas slaughter -- returned to the U.S. Tuesday night for what will almost certainly be days of questioning.

Marilou Danley flew from the Philippines to LAX where she was met by authorities. MSNBC got these images of Danley being escorted out of the Bradley International Terminal in a wheelchair.

Authorities want to know what she knew about Paddock's elaborate plan to spray the country music festival with bullets. Law enforcement will also grill her over the $100,000 Paddock reportedly transferred to the Philippines days before the shooting.

The mayhem that ensued in the minutes after mass murderer Stephen Paddock began firing at a crowd from his Mandalay Bay hotel room was captured by a cop's body cam ... and it's terrifying.

Las Vegas PD just released footage from one of its officers working with others to try to determine where the gunfire is coming from ... while also trying to direct people to safety.

The video of the chaos while gunshots continue to sound in the distance is disturbing.

The brother of mass murderer Stephen Paddock lost it Tuesday during a bizarre, rambling interview.

Eric Paddock spoke with CBS News and broke down, unable to talk for a time, before his thoughts about his brother meandered.

He says his family is torn apart over the deeds of his brother, and this isn't the Stephen they knew.

Eric says his brother transferred $100k to the Philippines for legit reasons ... to care for his girlfriend. Authorities say she's still a person of interest, but Eric thinks his brother manipulated her to leave the country so she wasn't around when he fired into the Vegas crowd.

Eric also says his brother was rich and generous with his money, sometimes spending thousands of dollars on sushi for friends and relatives.
