7:20 PM PT -- Mariah's reps tell us the alleged incident did not involve any members of her security team, and instead it was the venue's security.

All one of Mariah Carey's fans wants for Christmas is justice for a beatdown he says he got from a bodyguard in Las Vegas.

The alleged assault went down Saturday night after Mariah's show at Caesars Palace. The fan, Yaniv Elharar, says he started recording video of one of her bodyguards roughing up another fan. Yaniv claims the bodyguard saw him recording and flipped out ... smacking his phone away and punching him twice, in the chest and the ribs.

Based on photos of the alleged injuries ... it seems he was was also hit in the face, although Yaniv claims he doesn't recall it in the scuffle. He claims the bodyguard chased him out of the auditorium, and that's when he called LV Metro PD.

Khabib Nurmagomedov says he's going "The Walking Dead" route to make weight at UFC 219 -- telling TMZ Sports he'll hack off his own leg to hit 155 pounds in 10 days.

Don't worry -- he's kidding ... we think.

"I’m gonna cut my leg ... right or left, I don’t know," Khabib told us out in Century City.

On the real, Nurmagomedov says he's sick of everyone hating on his diet ... after a weight-cutting issue forced him outta his fight with Tony Ferguson back in March.

Speaking of Tony ... Khabib says he could whoop both Ferguson and Conor McGregor IN THE SAME NIGHT ... and he seemed dead serious about that, too.

Johnny Manziel's fiancee, Bre Tiesi, almost had one of her lips torn off by a dog ... but it looks like she's gonna be OK after one of the Kardashians' plastic surgeons worked his magic.

Bre detailed the scary incident on social media -- saying her lip was "legit hanging off" after she tried to break up a canine throwdown involving her two pups.

But the IG model wasn't about to let a random ER doc mess with her kisser ... so she hit up Garth Fisher -- a Beverly Hills surgeon who's worked on Kris Jenner -- and he stitched her up, good as new.

Well, not exactly ... but Bre says she should be scar-free in just a few weeks!

Not like she wouldn't be smokin' hot either way.

Macaulay Culkin made a bigger mistake than "Richie Rich" when he messed with wrestling star Swoggle this week -- and now the ex-WWE superstar is hell bent on REVENGE!!!!

Remember, it was Swoggle who was targeted by Culkin at a Bar Wrestling event in L.A. on Thursday -- with Mac hitting him with a flying splash from the rope!

But now, Swoggle tells TMZ Sports ... Culkin is GONNA PAY for his transgressions.

"Macaulay Culkin ... this is pro wrestling. This is my world. This ain't Hollywood, bitch!"

Talk about a rough day at the office ...

A Muay Thai fighter took a brutal elbow to the face during a fight in Thailand this week -- requiring emergency surgery ... but don't worry, HE'S OKAY!!!!

Pro fighter Jonny Betts was at the Patong Stadium in Thailand on Monday night -- when his friend, "Jeremy," suffered a skull fracture in the ring.

Betts says Jeremy was out of the hospital in just a few days after undergoing a procedure to "fix up the fracture with a titanium plate."

"No brain injury and he was never dizzy."

Get well soon, man.

Here's a video the NFL should show at the 2018 Rookie Symposium -- NY Giants WR Brandon Marshall being cussed at in NYC by a heckler ... and he handles it like a champ.

It all started when an NYPD officer approached Brandon's Rolls-Royce and started to write him a parking ticket. Like anyone, the WR wasn't happy about it.

A fan spotted the incident and started recording. He then asked Brandon for a selfie, but the NFL star wasn't in the mood (obviously) and declined.

The fan turned on Marshall and yelled at him, "That's why your team sucks, man. That's why your team sucks!"

He added, "What's y'all record?! F*cking bum!"

But, Marshall smartly kept his cool and walked away ... only saying one thing to the heckler, "Go to work." He left the situation without incident.

This had all the makings of a situation that could have gone very south ... and it didn't.

You guys give up or ya thirsty for more?!!?!

Macaulay Culkin channeled his inner-Randy Savage -- and dominated a pro wrestling match in L.A. on Thursday, culminating in a move where the actor FLEW OFF THE TOP ROPE!

Culkin was ringside at Bar Wrestling ... during a match between Joey Ryan, Candace Larae and Dick Justice VS. Peter Avalon, Ray Rosas and Swoggle.

In footage captured by ProWrestlingSheet, you can see Culkin -- in a Rowdy Roddy Piper shirt -- interfere with the match by using a trick from "Home Alone" ... rolling marbles into the ring!!

He then zeroes in on Swoggle and hits him with a splash from the top rope while the crowd chants, "Home Alone!"

It's awesome!

Soooo ... bring on the Wet Bandits?!?

If Keaton Jones REALLY wants to get bullies off his back, Rampage Jackson says there's only one way he can get the job done.

"I would kick somebody's ass!" Rampage told TMZ Sports. "You fight -- you go down swingin' -- they ain't gonna kill you, most likely."

The MMA star says the world's getting waaay too soft when it comes to bullying ... and throwing hands accomplishes something words never could.

"You get your respect and people won't mess with you no more. Most people are cowards, anyway. Most bullies are cowards."

And if Keaton needs to see how it's done, Rampage is scrappin' with Chael Sonnen at Bellator 192 in January.

Just 4 days before Damontre Moore was cut by the Dallas Cowboys, the NFL defensive end was in a crazy street brawl in Texas ... and it sounds like someone fired a gun.

TMZ Sports obtained footage from the Oct. 20 incident outside of Bottled Blonde beer garden -- where 25-year-old Moore was getting into it with a group of guys.

One witness tells us the fight was over a woman -- but the details are unclear.

What we do know ... Moore tries to fight two guys -- and ends up getting jumped pretty bad. One guy puts Moore in a headlock while 2 other guys swing on him.

Eventually, Moore gets out -- and tries to jump through the sunroof of a Porsche to try and punch the fleeing attackers. As the car peels out, you can hear what sounds like a gunshot.

Cops were called to the scene at 2:10 AM for possible shots fired -- but everyone left, so no arrests were made.

Moore was a member of the Cowboys at the time of the incident -- but was cut 4 days later, reportedly for "football reasons" ... to make room for another player on the roster.

We reached out to Moore and the Cowboys for comment -- so far, no word back from either.

A couple hypebeasts staking out a long line at a Fear of God pop-up went toe-to-toe and one of 'em landed an epic punch to the other's face.

The line of sneaker heads formed Tuesday night outside Maxfield LA ... anticipating the release of some new Fear of God shoes and clothing, but something went sideways quick. Maybe somebody cut the line ... who knows? But after some pushing and shoving 2 guys squared off.

Watch and see if you can guess who uncorked the KO before it happens.

Here's a story about a no-legged man in an ass-kicking contest ...

Ex-Olympic sprinter (turned convicted killer) Oscar Pistorius was involved in a prison fight in the South African penitentiary where he's locked up ... officials confirm.

The Blade Runner -- who's serving a 13-year prison term for the 2013 shooting death of girlfriend Reeva Steenkamp -- got into the scrap on Dec. 6.

Prison officials say Pistorius and another inmate fought "over the use of a public phone in the special care unit."

Pistorius only suffered a bruise. No word on the other inmate.

Not so tough without your gun, are ya?

Jermaine O'Neal knows all about player vs. fan fights (Malice in the Palace, anyone??) ... so when we got J.O. at LAX, we had to get his reaction to Quinton Jefferson almost going full Ron Artest at Sunday's Seahawks-Jaguars game.

"Just because we’re professional athletes doesn’t mean we should be treated like animals," the ex-NBA star told TMZ Sports. "We're there to do a job, whether you like us or not."

You've probably seen the video ... some d-bag Jags fans threw their drinks at Seahawks lineman Quinton Jefferson after he got ejected -- and he got dangerously close to going in the stands and giving them the business.

Jermaine says actions like that can't fly -- 1) 'cause it's wrong and 2) 'cause it might get your face broken.

Case in point ...

Conor McGregor actually had a shot against Floyd Mayweather ... but he would get straight-up SMASHED by Manny Pacquiao -- so says ex-UFC star Brendan Schaub.

We got Schaub -- an analyst on the MayMac media tour -- to weigh in on McGregor vs. Pacquiao with rumors of the super-fight swirling ... and he told TMZ Sports Conor doesn't have a chance in hell of upsetting Manny.

"I actually think it's a tougher fight for Conor," Brendan said. "Pacquiao's more of a pressure fighter, bigger puncher. Floyd Mayweather was the perfect matchup."

The big question -- will the fight actually get made?

Ty Dolla $ign and YG's alleged beatdown of an Australian soccer star apparently cost 'em big-time -- 'cause the guy says they dropped at least $100k to keep the matter out of court.

Aussie footballer Nelly Yoa tells TMZ he settled with Ty and YG for a low six-figure amount to avoid a potential lawsuit against them for allegedly beating the crap out of him in 2015.

We broke the story ... Nelly says the rappers punched and kicked him in the head when they tried clearing out a VIP room at a nightclub in Melbourne that he refused to vacate. He claimed the alleged beating cost him a soccer deal that woulda made him a fortune.

Nelly put T&Y on official notice a couple months ago, letting them know a lawsuit was coming.

UFC champ Max Holloway says Kobe Bryant has shown him the killer instinct it takes to be great ... crediting Mamba Mentality for his ass-kicking inside the Octagon.

"When Kobe is in Mamba mode he's an animal," Max told TMZ Sports. "He doesn't care about winning one time ... he'll play you 100 times just to make a point -- you suck, I'm the greatest."

It’s a mindset Max says helped him SMASH Jose Aldo in their rematch last weekend ... and one he plans to continue using to become the next big thing -- like a Kobe, LeBron, Tiger or Serena.

“These guys that I named -- they outgrow their sports."

Kobe’s actually a HUGE fan of one of Max’s biggest rivals -- but we got a feeling the Mamba can get down with the "Blessed Era,” too.

Arianny Celeste says if she was Conor McGregor's woman, Dee Devlin, there'd only be 1 way to handle his "date night" with Rita Ora ...

"WHOOP HIS ASS!!!"

FYI, McGregor got cozy with the pop superstar at London's Fashion Awards on Monday and then shouted her out in a club 2 days later -- begging the question ... is Dee really cool with that?!

The UFC's baddest Octagon girl told TMZ Sports she thinks Conor and Rita are probably just friends ... and he was just doing it for the cameras.

That said, Arianny says she'd straight-up KO Conor for doing her like that -- fling or no fling.
