Boxing

Baseball? Check. Football? Check. Basketball? Check ... and now Jay Z can add boxing to the list of sports in his Roc Nation sports empire -- inking super middleweight champ Andre Ward.

Ward -- who's 27-0 and recognized as one of the best pound-for-pound fighters in the world -- announced this morning, "It's official!! #NextChapter Happy to be a part of the @rocnation family."

It seems like a good union for both parties ... Jay's reportedly been trying to get into the boxing game for a while but was holding out for a fighter with real star-power.

As for Ward -- he hasn't fought in nearly two years due to business disputes with his former promoter ... but it's clear he feels Jay can get him back on track.

Plus, anything that brings you closer to Rihanna has got to be a positive.

Most people can't afford one Bugatti supercar, worth around $2 million -- Floyd Mayweather has THREE.

The boxing champ just showed off his insane car collection -- comprised of some of the most rare and expensive cars in the world.

Here's the checklist with approximate market values ...

Bugatti Veyron -- $2 millionBugatti Veyron -- $2 million Bugatti Grand Sport -- $2 million Ferrari 458 Spider -- $250kFerrari 458 Spider -- $250k Lamborghini Aventador -- $400k Porsche 911 Turbo S $180k Ferrari 599 GTB Fiorano -- $300k

Grand total ... $7.3 MILLION.

And unlike Justin Bieber, Mayweather has his own private jet ... and they don't exactly come cheap.

FYI -- Mayweather has reportedly made more than $400 MILLION in his career ... and clearly, he ain't afraid to spend it.

In what seems like a scouting trip for a possible Solange Knowles career change, Jay Z and Beyonce took in a Muay Thai fight during their vacation in Thailand.

It all went down at Patong Boxing Stadium in Phuket. There were kicks. There were punches. There was Beyonce sitting ringside while the violence unfolded ... all in a space that was roughly the size of an NYC elevator.

FYI -- Muay Thai is the national sport of Thailand ... where fighters are allowed to use their knees, elbows, feet, shins and hands to strike their opponents.

High heels are strictly prohibited.

Justin Bieber just got CALLED OUT by former two-time boxing champ Fernando Vargas -- who says his teenage son Fernando Jr. would KICK THE CRAP out of the Biebs ... and wants his chance to do so.

The Vargas' were doing an interview with BBoxingnews.com when the elder Fernando was asked if he'd let Jr. -- an undefeated amateur-- spar Justin since he's been training with Floyd Mayweather.

"Bring him down, we'll meet him anywhere, I'd love to do a fight with Justin Bieber and my son."

The younger Vargas weighed in too, saying he's seen Justin training with Floyd on social media and says he definitely wants to test his pretty Canadian chin.

"He's alright, he's cool. If he's trying to do [Mayweather's famous shoulder roll technique], I don't see it happening for him."

Check out the video -- Both Fernandos seem incredibly serious about the prospect of fighting Bieber and based on what we see of Jr. working the mitts we have a suggestion.

Back away slowly Justin ...

The man who "boxed" Mickey Rourke in Russia is PISSED -- telling TMZ Sports the actor's people are STIFFING him out of $5,000 he was promised for the fight.

We spoke with 29-year-old Elliot Seymour who says he was supposed to be paid $15k to step in the ring with the 62-year-old actor ... but only got $10k.

Seymour says the whole situation was sketchy -- but insists he was NOT paid to take a dive.

"People can say whatever they want ... if you've never been in a fight before in your life, you have no idea what it feels like to get hit."

Despite the financial dispute, Seymour says he's down to fight Mickey again -- if Mickey wants a rematch.

Rourke's boxing manager tells TMZ ... Seymour only got $10,000 because that's the most he can carry through customs. He says Seymour will get the other $5,000 next week, saying, "I think the poor kid is just enjoying the attention a little too much and is beginning to talk to the press about anything just to get more attention."

Boxing champ Peter "Kid Chocolate" Quillin is making his silver screen debut next year -- as none other than the original Black Mamba himself Roger Mayweather ... TMZ Sports has learned.

Quillin tells us he auditioned, and landed the small role in an upcoming flick entitled "Bleed For This" -- a true-life story centered around the life of world champion boxer Vinny Pazienza, played by "Divergent" actor Miles Teller.

"Only Roger Mayweather can be Roger Mayweather," Quillin says ... "What I tried to do is bring a fighter's mentality to his character."

The 31-year-old champ says the hardest part of the job was nailing down the fight choreography -- since he's not used to scripting out his moves in the ring -- but says there's one part of the gig that came naturally.

"I remembered all of my lines. I didn't f**k up."

Boxer Jermain Taylor has finally been hit with charges for SHOOTING his cousin at his Arkansas mansion back in August -- and if convicted, could face up to 26 years behind bars.

Taylor's wife called 911 immediately following the August 26th shooting ... and Jermain can be heard on tape admitting he shot a man. He also warns police, "Better come get him before I kill him."

At the time, Taylor claimed the man was an intruder and he was protecting his property -- but prosecutors are calling BS ... telling us they're not buying Taylor's self-defense story.

Now, he's been charged with battery and making terrorist threats -- both felonies. If convicted on both counts, he could face a maximum of 26 years in prison.

As for the victim, we're told he survived the shooting. No word on his current condition.

His GF claims Floyd Mayweather pulled a gun on her ... and repeatedly beat her up ... but Nelly says HE'S not going to bury the hatchet with the boxer because "I ain't got no hatchet to bury."

It's an interesting statement ... considering Nelly's girlfriend Shantel Jackson filed a bombshell lawsuit against Mayweather earlier this year ... essentially saying Floyd terrorized her during their 2-year relationship.

Floyd and Nelly have also exchanged barbs in the media -- but last night, when Nelly was leaving Pinz bowling alley in L.A., the rapper insisted he's not the one holding the grudge.

As one law enforcement source put it, "[Floyd] goes in and pulls a 'Do you know who I am' and does inappropriate things with some of the women."

We spoke with honchos from multiple strip clubs who tell us they will NOT heed the warnings, because they've never had a problem with Floyd. Plus, everyone knows he spends a TON of cash.

Sources close to Floyd tell us the boxer is adamant he has NEVER done anything wrong at a strip club -- particularly with women -- and has no idea why cops would have him in their crosshairs.

Boxing legend Leon Spinks was taken down after going a few round with some chicken wings ... TMZ Sports has learned.

We broke the story ... Spinks is currently hospitalized in Nevada -- and now, we've learned Leon's medical problems can all be traced back to a chicken wing meal gone bad.

Leon's attorney tells us Spinks is known to his friends as the "Chicken Wing King" -- and during a recent meal, accidentally swallowed a bone ... which got stuck in his intestine.

Spinks has undergone two surgical procedures so far -- with a 3rd scheduled for later today. We're told Leon is conscious and on the mend.

We're also told ... Leon's current wife Brenda is adamant she has power of attorney over Leon -- despite a claim to the contrary by Leon's ex-wife Betty.

As we previously reported, Betty says Leon empowered her to call the shots regarding his health after they divorced back in 2004.

But Leon's attorney tells us, "Brenda and Leon have a power of attorney agreement. Betty's power of attorney was expressly revoked by Leon."

Boxing legend Leon Spinks -- who famously beat Muhammad Ali in 1978 -- is hospitalized in Las Vegas, TMZ Sports has learned ... and his friends say the situation is very serious.

Sources connected to the 61-year-old Olympic gold medal winner tell us ... Spinks underwent surgery this weekend for abdominal problems (his 2nd surgery for the issue) and there were complications during the surgery.

We're told the situation seemed dire at first ... but Spinks seems to be doing better.

Leon's wife issued a statement saying, "It's going to be a long road ahead, but he's strong and he's starting to recover."

Leon's good friend Tony Orlando -- the famous singer -- is asking people to "Please pray for my friend Leon Spinks" ... and said the boxer is "facing the greatest fight of his life."

A former heavyweight boxing champ who's OBSESSED with fighting Wladimir Klitschko has taken his pursuit to the sea ... chartering a boat to HARASS Klitschko this morning while he was out paddleboarding in Miami.

The video is maniacal -- showing Shannon Briggs hammering Klitschko with taunt after taunt ... while buzzing right by the guy ... eventually knocking him off his paddle board.

At one point during the incident, you can see and hear Klitschko tell Briggs, "You crossed the line."

Briggs has been all over Klitschko recently in an effort to coerce him into stepping back in the ring so they can fight.

Briggs recently found WK while he was eating lunch at an Italian restaurant and ignited a physical confrontation in which Briggs cut his foot on broken glass and ended up in the hospital.

Michael Jackson's son could be the next great boxing prodigy -- because Floyd Mayweather says he is going to PERSONALLY train Prince Jackson ... now that he's apparently joined The Money Team.

Floyd was PUMPED when he saw the pics of Prince rollin' around Calabasas this weekend in a truck covered in "The Money Team" decals -- and yesterday, Mayweather told us he can't wait to train the kid.

"I haven't worked with him yet, but I look forward to working with him when I get back to Las Vegas," Mayweather told TMZ Sports.

But Prince's uncle Jermaine Jackson says all is not as it appears ... telling TMZ Sports his nephew is NOT an official TMT member and only got into the TMT vehicle because he likes big trucks.

Doesn't seem to matter to Floyd ... at this point, seems Prince is officially in the crew ... whether Jermaine likes it or not.

Two hot, young chicks strapped on boxing gloves ... in bikinis ... and went at it INSIDE a Miami nightclub to celebrate Andre Berto's 31st bday ... and TMZ Sports has the footage.

The 2-time welterweight champ turnt all way up Mokia Lounge in Miami Beach recently -- alongside big stars like MLB pitcher Aroldis Chapman and fellow boxer Adrien Broner.

The scene was crazy ... huge bottle of champagne, scantily clad women, fancy cake -- and Berto tells TMZ Sports the whole thing was "epic!"

"We partied all night! That s**t was nuts!"

Happy bday!

Here's some pretty amazing video of boxing superstar Adrien Broner turning ALL THE WAY UP in a nightclub in ATL this weekend.

Dancing like his life depends on it? Check.

Clutching a bottle of expensive champagne? Check.

Wearing a half-open shirt that would make Magnum P.I. proud? CHECK! CHECK! CHECK!

It all went down at Mansion Elan nightclub ... where Broner was partying with a bunch of big stars like Lil Boosie and Yo Gotti who were all in town for the BET Hip-Hop Awards.

He's the best fighter in the world -- by far -- but Floyd Mayweather still invests in protection ... bringing SIX huge dudes to watch his back at one of the most famous chicken joints in the world.

Floyd and his posse hit up Roscoe's Chicken and Waffles in L.A. on Friday -- and on the way out, Money hid behind his wall of muscles as he and his lady friend made their way to a waiting SUV.
