Fights

Tyga's cruise ship performance ended with a bang, a full-on fight between his hype man, DJ S.B. and one of the guys from EDM trio Cash Cash -- what's up for debate is ... who started it.

Things went south early Saturday morning aboard the Inception at Sea cruise festival. Tyga started his set more than an hour late ... which eventually postponed Cash Cash, which was going on after him.

Sources close to Tyga tell TMZ ... when he wrapped up, the Cash Cash guys began unplugging S.B.'s gear. That sparked a verbal dispute, and then Jean Paul Makhlouf allegedly threw the first punch.

Now, the Cash Cash guys admit there was a verbal altercation, but claim Tyga's crew struck first. Makhlouf suffered a concussion, injured kidney and several bruises, according to his rep. Cash Cash was unable to perform.

No one's talking lawsuit ... yet, anyway.

We're told Tyga had nothing to do with the fight, he was already offstage.

Aaron Carter played judge and jury in Malibu, threatening to lock up a driver who gave him the bird ... and TMZ got video of the insane roadside conflict.

Sources on scene say Aaron went ballistic after a Volvo driver laid on his horn at a busy intersection, accusing Aaron of making him miss the light. We're told the Volvo driver punctuated the exchange by flipping a middle finger at Aaron.

That's where this video picks up -- Carter pulled into a nearby parking lot, got out with his bulldog and yelled at the driver to pull over so they could fight. Carter also said he was going to get the guy arrested ... for the flick off.

When the driver tells him to "Go home!" Aaron's response is classic ... "Oh, you mean my $2 million mansion?" Check out the altercation -- even Aaron's dogs could tell this was a s*** show.

A rep for Carter tells us he wasn't in the wrong and was just standing up for himself.

Tension at a Donald Trump rally finally reached boiling point ... as multiple fist fights broke out in Chicago forcing the candidate to pull the plug over safety concerns.

The crowd was fired up and cameras were rolling even before Trump arrived, and the video is intense -- supporters and protesters squared off all over the arena on campus at the University of Illinois at Chicago.

Since Trump wasn't there, microphones weren't on yet ... but the rage is still clear. This all started simmering much earlier in the day, outside the arena.

Worth nothing, this morning Trump applauded the North Carolina man who sucker-punched a protester.

Kim Richards got so riled up during a fight on her new reality show 'The Mother/Daughter Experiment' ... the gloves didn't come off but her sweater did.

TMZ obtained a clip of Kim and former "Bad Girls Club" alum Natalie Nunn getting in each other's faces ... you gotta see it.

Kim seems sober as she tries to protect her daughter, Kimberly, and Shar Jackson's daughter, Cassie, from Natalie's wrath.

You know what they say ... never get between a mama bear and her cub.

2:23 PM PT -- We spoke with a rep for the Scottsdale PD who tells us they have reviewed the video and contacted the off-duty officers who were at the scene.

We're told the cop on scene felt the situation "did not rise to the level of a criminal violation" so no one was arrested.

"There was no crime reported and no victims came forward."

You're about to watch a video of a man protecting his entire career ... when Broncos QB Brock Osweiler is attacked by a guy outside of a pizza place -- but smartly REFUSES to fight back.

Katt Williams had a crazy night in Philly ... bum rushing the stage at a rap show, punching a guy and ultimately coming up on the losing end.

It all went down Sunday night at the Trocadero Theatre ... where Beanie Sigel, Jahlil Beats, Jadakiss and a few other rappers were performing.

Williams was all over the place ... freestyling onstage, randomly doing pushups and standing around in a fight stance for no reason.

Williams suddenly ran full speed at someone onstage and clocked them. The dude he decked had a loyal entourage ... which beat Williams down.

No one was arrested.

Williams has had an interesting few days, to say the least. He was arrested last week in Georgia for allegedly punching a store clerk ... a day before that, he allegedly held five women at gun point ... and then a few days later he got into a fight on the streets of Los Angeles.

Katt Williams is racking up alleged crimes coast to coast -- he was also involved in an L.A. altercation and he's considered a suspect ... TMZ has learned.

Katt tells us he saw a car accident Tuesday outside his hotel and went down to the scene to help the victims. But while he was doing that, he says onlookers, who he described as "rappers," started making fun of his height.

Williams stands about 5'5" and he says the "rappers" were all six feet or taller. He says when he told them to shut up ... one of them hit him, so he struck back in self-defense.

He told a similar story about the 2 incidents in Georgia -- the first with 5 women in Atlanta on Sunday, and then his arrest at a pool supply store on Monday. He's accused of punching in all 3 cases.

Tough guy respects tough guy.

Vinnie Jones says when it comes to UFC fighters, he's all about Conor McGregor.

Vinnie joins a huge list of celeb McGregor supporters -- one that already includes Shaq, Arnold Schwarzenegger, U2's The Edge, Gordon Ramsay and many many more.

It'll be interesting to see if Nate Diaz can rally up some celeb support before the two do battle at UFC 196 this weekend.

One thing's for sure ... Nate's bandwagon will certainly fill up if he wins.

Stevie J was flattened outside a North Carolina nightclub ... and despite protestations he left unscathed, the video tells a very different story.

The brawl with Stevie went down outside Charlotte's Empire Lounge. There's a report things got so heated Stevie's van got shot up, but he insists that's not the case.

The "Love & Hip Hop: Atlanta" star says the incident was triggered by club security who roughed up a patron. Stevie says since he was hosting the event, the patron thought he was responsible, so when Stevie left the club the guy and his posse jumped him.

While Stevie insists he left unscathed, his pal and blogger FreddyO left with a gash in his head.

A celebrity doctor who's famously treated tons of Hollywood stars has a message for embattled NFL defensive end Dante Fowler -- CALL ME, I CAN HELP YOU!!!!

Nate Diaz doesn't even need to show up to UFC 196 ... 'cause according to former WBC boxing champ Andre Berto fate is already sealed ... Conor McGregor's gonna kick that ass.

Berto was leaving Playhouse when we got his thoughts on the fight ... who better to ask than a guy who makes a living punishing faces himself, right?

Not only that ... but Andre comes from an MMA family with his father, brother, and SISTER all having competed in the Octagon.

Check out the clip -- Berto is Team McGregor all the way, telling our guy he thinks Nate's tough ... but not tough enough to take out the pride of Ireland.

As far as a matchup between Conor and Jesus ... Berto wouldn't give us a straight answer. Although we already know what McGregor thinks.

Dog the Bounty Hunter squared off with an old opponent in Las Vegas and when fists started flying cops had to get involved.

Dog was at Luxor in Vegas Wednesday for a bail bonds conference when he ran into an insurance broker named Ronnie Frank, who's had beef with Dog in the past.

A rep for Dog says Frank got in a threatening stance and said, "I'm gonna kill you, you long-haired mother f*****." Dog's security guard tried to break it up by putting a hand on Ronnie's chest.

We're told Ronnie slapped his hand away, and that's when Dog's guard punched Ronnie in the face. Hotel security called Vegas cops, who cited Dog's guy for battery.

On a positive note for Dog -- Beth was voted President of the Bail Bonds Association later that day.

Justin Bieber and his crew were NOT the cause of a nightclub brawl in London Wednesday night ... but he was the reason for the ruckus.

Bieber partied at Tape nightclub following the Brit Awards and reportedly left early after someone from his entourage started a big fight.

But Jacobi Anstruther-Gough-Calthorpe (that's a mouthful) -- founder and manager of the club -- tells TMZ the fight started when a man smuggled a camera into Tape and tried to snap shots of Justin in VIP.

The club has a strict no camera policy, so security quickly booted the guy.

Anstruther-Gough-Calthorpe says Bieber didn't leave then ... he simply moved to the "members only" section in the back, where he hung out with Diplo and Metro Boomin in the private recording studio and played music for the rest of the night.

Nice nightcap after his win for best International Male Solo Artist at the award show.

Here's Conor McGregor ... doubling down on the racist smack talk.

McGregor referred to Nate Diaz as a "cholo gangsta from the hood" during the insane news conference for the UFC 196 fight Wednesday day ... and clearly, he's not letting up.

UFC champ Conor McGregor called Nate Diaz a "cholo gangsta from the hood" in one of the most hate-fueled pre-fight press conferences ever.

Nate said everyone in the UFC -- including Conor -- was on steroids. Conor went nuts and said he was absolutely not.

Nate, who's stepping in at the last minute to replace the injured Rafael dos Anjos in UFC 196 on March 5th, was goaded by Conor, who said Nate "makes gun signs with the right hand and animal balloons with the left hand."

Conor was referring to Nate's side jobs to make money. Conor was quick to add he's now a millionaire who shops on Rodeo Drive.

You have never seen this kind of hatred.

Four of the "Little Women: Atlanta" cast members got into a knock-down, drag-out fight that ended with one of them -- the pregnant one -- ending up in the hospital.

In an episode airing Wednesday ... Emily and her friend Bri got into it with twins Amanda and Andrea Salinas. The twins just started waiting tables at the same club where Emily and Bri work as dancers -- and as everyone knows ... waitresses and dancers don't mix.

Watch, Emily (with cornrows and a "Boss" tee) is the one with child ... but she didn't hesitate to throw down. We're told she went to a hospital for a checkup after the fight.
