** WARNING: Horrible language, violent threats, and homophobia **

Adrien Broner just reignited his beef with Floyd Mayweather ... calling the Money Man a "bitch," and it's all over his relationship with a rising boxing superstar.

The boxing star is Gervonta "Tank" Davis ... an undefeated champion and member of Mayweather's Money Team who recently called out Broner, demanding a fight with him.

Broner apparently took the challenge as the ultimate sign of disrespect, claiming he and Davis are pals, and alleging Floyd tricked the kid into making the challenge, and he ain't happy.

He also vows to do to Davis what Faizon Love did to that guy at the airport. You know the video.

We warned you, watch at your own risk.

Wanna drive like Floyd Mayweather? If you've got a cool $4 mil you can buy his old 2015 Bugatti ... on eBay!

TMZ Sports has learned the boxer recently sold his 2015 Bugatti Grand Sport Vitesse to the Luxury Auto Collection in Scottsdale, AZ ... which is now offering it up with a $3.95 million price tag.

L.A.C. even created a post on eBay in case any rich people wanna get in an online bidding war over the whip.

The listing says the car has a top speed of 254 mph, with a 0 to 60 time of 2.4 seconds.

"With only 150 Grand Sports built worldwide, this car was one of the last Grand Sports brought to the US this is an extremely rare opportunity to own a piece of automotive and boxing history."

Mayweather also sold his 2011 Bugatti Grand Sport to L.A.C. ... which is on sale for $2.45 mil.

Ex-boxing champ Kelly Pavlik worked out two plea deals in a single day, resolving charges relating to a pellet gun attack from 2015 and allegations of breaking and entering in 2011.

As we previously reported ... the former WBO and WBC middleweight champ was charged with felony assault in 2015 after he shot a guy with a pellet gun.

Prosecutors added the breaking and entering charge stemming from a 2011 incident where he allegedly broke into a foreclosed house and stole piping.

A rep for the Mahoning County Court tells us Pavlik pled guilty to a reduced charge in the gun case on Thursday. He was sentenced to 6 months in jail, but the judge suspended the time.

In the breaking and entering case, he entered a supervised diversion program that will last at least a year. If he successfully completes the program, the charge will be dismissed.

Conor McGregor laced up his gloves and boxing shoes and hit the asphalt in Ireland for a little outdoor training for the Floyd Mayweather fight ... and he looks good.

The UFC star ran through some speed drills with fellow UFC fighter Artem Lobov -- who also happens to train with Conor's coach, John Kavanagh.

Floyd Mayweather has one-up on Superman ... his cape is designer made.

The boxer was pre-gaming in Miami before hitting the clubs with his pal, Adrien Broner -- rocking a Versace robe with a matching blanket he used as a cape.

A short time later, they hopped in a TMT Jeep -- customized with TMT rims.

Inside the club, there was dancing, drinking and ladies.

Hayden Panettiere says she's "pretty confident" her baby daddy, Wladimir Klitschko, will destroy Anthony Joshua when they face off later this month ... telling TMZ Sports "we're ready."

Hayden breaks down her role in Klitschko's preparation ... and says she's gonna be right in the front row when it all goes down at Wembley Stadium on April 29.

Conor McGregor vs. Floyd Mayweather will SUCK ... so says Lennox Lewis who says the hypothetical match is more of a spectacle than a real fight.

The former heavyweight champion of the world says he respects both guys in their respective sports -- but putting them both in the same ring is a disaster waiting to happen.

Roy Jones Jr. says he's NO LONGER in the cockfighting game -- telling TMZ Sports his roosters are now used to train human fighters ... instead of feathered ones.

Photos have surfaced of rooster cages at Roy's Florida compound -- leading some to suspect the boxing legend was involved with underground bird fighting.

But Roy says the rumors are 100% false -- insisting he quit the sport when it was outlawed in 2008 in Louisiana, the last U.S. state to ban the sport. Although he enjoys cockfighting, Roy says he would never break the law.

Roy says he would love to move to a country where the sport is legal -- like Mexico or Puerto Rico -- but he's too busy training boxers ... and uses the birds as part of his workout regimen.

Picture that scene from "Rocky II." Roy says he's been using that training method for decades and it helps with hand eye coordination.

As for claims cockfighting is animal abuse, Roy is adamant he's not forcing the birds to do anything they're not biologically programmed to do ... and says most cockfighters love their birds like their own children.

Floyd Mayweather will still be welcome at his daughter's cheerleading events -- despite the showdown with officials over the weekend ... TMZ Sports has learned.

Floyd Mayweather exploded on the judges at a youth cheerleading competition this weekend ... claiming they cheated his daughter's team out of the title and he was PISSED.

Look out, Sex Panther ... Floyd Mayweather is now looking to conquer the smell game.

Here's proof the Russians do more for fun than just (allegedly) sabotaging democracy ... Sergey Kovalev firing a SICK gold-plated Tommy gun during a trip to a famous Russian weapons museum.

Krusher is from Kopeysk (where you can get a 5 star hotel for $75 a night, book now), but jaunted over to the Arsenal Museum of the Zlatoust Weapons plant and got some action in.

The weapon looks pretty sick, and although Sergey struggles at first, he manages to get a shot in after some help from the staff.

BTW ... all this happened indoors, so hopefully they were blanks. But, it's Russia, so you never know.

UPDATE -- We're told the gun isn't a traditional "Tommy Gun" but rather a Russian PPSh-41 ... essentially the Russian version of the Tommy Gun.

Pandemonium occurred at a Golden Gloves boxing event in L.A. on Wednesday -- when fans stormed the ring at a youth tournament and fought it out ... with one guy catching a haymaker right in the face.

Oh, and a woman hit a man with a steel chair!!!!

It all went down at a Golden Gloves qualifier tournament at a rec center 2 miles from Dodger Stadium -- when fans got pissed after an alleged late punch during a bout between teenagers.

One witness tells us people began to scream at each other -- then they stormed the ring -- then the punches flew.

The witness adds, "Chairs were thrown and people were hit with chairs. Tables were broken. A woman even hit someone with a chair."

Miraculously, no one was seriously injured. Cops were called to the scene but the fight was over by the time police arrived. No one was arrested. Some of the fans are pissed about the lack of security at the event.

But get this ... we're told the brawl eventually ended on its own and the boxing tournament continued.

Floyd Mayweather has a VERY different media strategy than his pal, Donald Trump!!

The boxing superstar was out spending some of his millions in Bev Hills on Wednesday -- when he took a moment, called over ALL the paparazzi and gave 'em a pep talk right in the middle of the street.

"I support all of you 100%," Mayweather said ... "Without the media, I wouldn't be where I'm at."

Of course, the guys ate it up ... and then hammered Floyd with Conor McGregor questions -- continuing the hype machine that could lead to his biggest payday of all time.

Another Roy Jones will be dominating professional sports very soon ... except it won't be in boxing, and he won't be Jr., 'cause this RJ will be tearing up the NBA, according to his dad.

His dad is Roy Jones Jr., one of the greatest boxers of all time and he tells TMZ Sports his kid Roy Jones III -- who's killing it in Florida HS hoops -- is destined for NBA greatness.

"I know he has that potential, he's talented enough to make the NBA, yes."

Don't get it twisted, Roy says he's not at all pulling a LaVar Ball -- making outrageous claims about his kids -- but just says he believes in his son, who Roy says is getting recruited by colleges now.

Speaking of LaVar, Jones weighs in on the whole Ball vs LeBron situation, and what he has to say is very, very interesting.

Floyd Mayweather is selling one of the most rare and expensive cars in his collection -- his Koenigsegg CCXR Trevita -- one of only 2 in the world.

Floyd's car guy, Obi Okeke, tells TMZ Sports Mayweather is selling the car to replenish his multi-million dollar car collection. We're told FM also plans to purchase a $20 million yacht, 'cause ... why not?

Mayweather bought the insane car -- which has 1018 horsepower, top speed of over 254 MPH, and 0 to 60 time of 2.8 seconds -- for $4.8 million in 2015.

The whip is currently being stored in L.A. while a stupidly rich buyer is found.
