Oscar De La Hoya has a challenge for President Trump -- he's "daring" POTUS to come to the Canelo Alvarez vs. GGG fight on May 5 ... to prove he doesn't really hate Mexican people.

"I always have binoculars ready for Donald Trump because I'm not gonna sit him ringside," Oscar tells TMZ Sports ... "I'm gonna sit him way up there in the stands with all the Mexicans and all the fight fans from Kazakhstan!"

"I dare him to come! It'll be great!"

Oscar says he knows Trump is a fight fan -- but tells us he's probably rooting for Gennady Golovkin because "I don't think Trump is a Mexican supporter. He's more of a European supporter."

The Floyd Mayweather 41st birthday extravaganza continued on Sunday -- featuring Drake hitting the roller skating rink while his own music played in the background!

It was the 3rd major event for Floyd's birthday -- and maybe the most fun -- as the TMT crew took over at World On Wheels in Los Angeles for an old-school roller skating party.

Floyd tore it up in his Nike skates (as usual) ... and Drake didn't do too bad, either -- casually circling the rink in his in-line skates while the DJ played his hit, "Right Hand."

Afterward, Drake hit the arcade section -- and battled it out with the basketball free-throw game.

Floyd seemed to enjoy himself, too -- telling TMZ Sports he wants to keep the party going until 2019!!

He also bragged about his new 2018 Rolls-Royce ... which hasn't been released to the public yet.

Floyd Mayweather turned 41 years this weekend and to celebrate he threw an insane party for himself.

The bash went down Saturday night at The Reserve in Downtown L.A. Floyd joined Mariah and Jamie at the DJ booth and it looked like they were having a super fun time. Other guests included Wiz Khalifa, Bobby Brown, John Singleton, Stephen Belafonte, and Laura Govan.

The theme of the party ... Bank of Mayweather. Check out the video ... the font is the same as Bank of America, which makes sense -- Floyd seems to think he rivals B of A in assets.

Floyd got lots of expensive gifts ... gifts he bought himself, which include an ridiculously expensive watch and necklace, a Bugatti and a Rolls Royce.

Here's video of Sugar Ray Leonard and Bruce Buffer giving daps at LAX ... then giving waaay different takes on how Floyd Mayweather would do against Conor McGregor in the UFC!

The meet-up happened courtesy of our photog -- who spotted the 2 legends randomly crossing paths. (Only in L.A., right??)

Sugar, of course, wasn't about to throw his fellow pugilist under the bus -- saying Floyd's "always" got a shot.

Bruce, on the other hand, was happy to -- telling us why it'd be "a very quick night" for Mayweather inside the Octagon.

Floyd Mayweather's good looks are also undefeated!

Here's a 21-year-old version of the fresh-faced professional boxer after winning a fight back in 1998 (left) and 20 years later ... the champ -- who celebrated his 41st birthday earlier this week -- at the All-Star Game in Los Angeles (right).

Knockout.

The question is ...

Nate Diaz ain't even close to a UFC comeback -- so says Dana White, who tells TMZ Sports it's clear to him that Nate "doesn't wanna fight."

Dana's so sure ... he says it's MORE likely we see Conor McGregor vs. Floyd Mayweather inside the Octagon than a trilogy fight between Conor and Nate!!

"We've been hitting him up since the last time he fought [UFC 202], offering him fights, and he's not interested in fighting," White told us earlier this week.

FYI, the UFC honcho also told us he's talked with Floyd's camp, but isn't "in active negotiations."

One guy who Dana says IS interested in throwing down right now -- Nate's older brother, Nick Diaz, who hasn't fought in over 3 years!!!

There's more -- Dana confirmed who Tyron Woodley's next title challenger is gonna be (and if ya haven't already guessed ... it ain't Nate).

Floyd Mayweather rolled out $2 MILLION in cars, jewelry and cash to dominate the Rodeo Drive shopping scene in Bev Hills ... and gave TMZ Sports a private tour of his new toys.

First off, our guy tried like hell to press Floyd on the possible Conor McGregor rematch -- but the dude bobbed and weaved like ... well, like he's Floyd Mayweather.

Instead, Floyd bragged about his upcoming 41st birthday celebration -- and showed us the new $600,000 Rolls-Royce and $1.3 MILLION Bugatti he's using to drive him around L.A.

Oh, he also bought a new $100,000 Rolex and showed off about $100,000 (maybe more?) in cash he had on him the entire time.

The video is an embarrassment of riches -- so, naturally, we had to ask what's next for the boxer?

What he says actually makes a lot of sense ...

Heavyweight champ Deontay Wilder boldly claimed he's so good, he would have even knocked out Mike Tyson is his prime.

Mike Tyson respectfully disagrees.

"Iron Mike" was leaving Mastro's Steakhouse in Beverly Hills on Wednesday when we asked him about the statement Wilder gave us last month -- that there's no fighter in history who could beat him.

That includes a 1986 Mike Tyson.

"I don't think so," Tyson told TMZ Sports.

Lennox Lewis has previously weighed in on the debate -- taking Tyson over Wilder.

"I like Wilder but he’s never been in there with someone that ferocious who truly wants to break his ribs with every punch. I don’t see it!"

Stop us if you've heard this one before ...

Floyd Mayweather hit up a crazy expensive restaurant sporting a crazy expensive watch -- and couldn't wait to show off his jewelry on camera!

This time, Floyd -- surrounded by his TMT bodyguards -- was in the mood for fancy Chinese food at Mr Chow in Bev Hills ... and on the way out it, he let his blinged-out wrist do the talking.

As we've previously reported, Mayweather has an insane watch collection -- including a $2 MILLION diamond-covered timepiece ... which he showed off back in 2016.

He also bought a $1.1 million diamond-covered Hublot watch during a shopping spree at a mall in Dubai back in 2015. It's one of the most expensive watches in the world.

No word if the watch he rocked on Tuesday is brand new or an old favorite -- but one thing's for sure ... it's expensive.

Conor McGregor hasn't stepped inside the Octagon in over 15 MONTHS ... and UFC star Khabib Nurmagomedov says that's proof he ain't fighting EVER again.

At least, not in MMA.

"I don’t think he gonna come back," Khabib told TMZ Sports outside Jay Glazer's MMA gym in Hollywood.

"When is Conor compete last time in MMA? Long time. He's boxing guy."

Khabib says McGregor's team is focused on a rematch with Floyd Mayweather ... instead of a real fight against him or Tony Ferguson -- who he's facing at UFC 223 in April.

Khabib also told us his contract for the Ferguson scrap explicitly states they're fighting for the "real belt" -- which means the UFC is "100%" stripping Conor of his lightweight title.

FYI, Dana White still hasn't made an official decision on Conor's championship status or his future with the UFC.

Stay tuned ...

Former boxing champ Adrien Broner was arrested in Atlanta Monday night for allegedly sexually assaulting a woman at a local shopping mall, TMZ Sports has confirmed.

Officials tell us ... cops were called to the Lenox Square shopping center Monday evening where a woman told police Broner had " inappropriately groped her."

Broner denied the allegation -- but after being interviewed by cops, they believed there was enough evidence to arrest him for misdemeanor sexual battery.

The 28-year-old was transported to Fulton County Jail without incident.

He's scheduled to face a judge around 9 AM local time. His booking sheet lists him at 5'8" and 160 lbs.

BSO is reporting the incident took place in front of a Louis Vuitton store.

Broner has had numerous outside-the-ring issues over the years -- including a September incident where he socked a man in the face on the Vegas strip.

His "big bro," Floyd Mayweather, tried to step in and mentor him back in 2017 ... but it doesn't seem to be working.

Wanna see Tonya Harding knock a chick out cold with a devastating right cross?

You're in luck ... because TMZ Sports found extremely rare footage from Tonya's last professional boxing match -- and she straight DESTROYED her opponent.

It all went down in 2005 -- when a 35-year-old Harding (3-3) stepped into the ring to face Brittney Drake in Brittney's first pro boxing match, a fight promoted by Celebrity Boxing creator Damon Feldman.

The Tom Brady of boxing is Roy Jones Jr. -- so says Roy Jones Jr. ... who broke down why he and Tom stand out among the G.O.A.T.s in their respective sports.

"You have to be able to rate people by how they perform under pressure, when things don't go their way," Roy told TMZ Sports.

Case in point -- Brady rallied the Patriots from 25 points down in last year's Super Bowl ... and RJJ told us there was a time in his career where he accomplished something similar.

As for the Brady of MMA ... Roy agrees with Dana White and says it's Anderson Silva -- who he's still gunning to face inside the ring.

RJJ didn't have an official update on that super-fight, but he did hint at making progress with Dana -- who, FYI, has agreed to broadcast his Feb. 8 "retirement fight" vs. Scott Sigmon on UFC Fight Pass.

Conor McGregor says Floyd Mayweather needs to stop flirting with an MMA fight and ACTUALLY BOOK IT -- or he'll regret it until the day he dies.

"If he does do it, I know he's flirting with it, I would have respect for him," McGregor told Adam Glyn.

If Floyd is just messing around and won't take a real MMA fight, Conor says, "it will follow him for the rest of his days that he did not do it."

As TMZ Sports previously reported, the head of Showtime Sports says he's talking with Floyd about getting a deal done ... and expects the fight would pay Floyd in the 9-FIGURES.

Floyd Mayweather is heading to Minnesota where he's set to meet with Showtime honcho Stephen Espinoza ... and the two will DEFINITELY be talking about a possible MMA fight.

"It will be a topic of conversation," Stephen told TMZ Sports ... acknowledging Floyd's recent videos from inside an MMA cage are VERY interesting.

"There's a chance ... whatever he puts his mind to, he sort of wills into happening. [Floyd] willed the McGregor fight into happening. So, if he sets his mind to it, it'll happen."

And how much money would it take to lure Floyd back?

"He's not an 8-figure guy anymore. He's a 9-figure guy," says Espinoza, the president of Showtime Sports and event programming.

Bottom line -- if Floyd wants an MMA fight, sounds like Showtime is 100% behind him.

11:39 AM PT -- Sources connected to Floyd tell us ... Floyd rented out the entire Syndicate MMA gym in Las Vegas on Monday for a private workout session.

As far as the MMA training goes, we've spoken to multiple people and everyone is being VERY tight-lipped about what Floyd was working on inside the gym.

We obviously know he spent some time in the cage -- but no one will say if Floyd was doing actual MMA training or just getting his usual boxing workout in with a change of scenery.

FYI, a ton of legit pro MMA fighters train at Syndicate, including UFC Hall of Famer Forrest Griffin, Jessica-Rose Clark, Mike Pyle and Julian Marquez.

11:28 AM PT -- Conor has seen the video and offered up some thoughts ...

"Hahahaha very good. Keep up the good work my son. Yours sincerely, Senior."

Well, here's Conor McGregor's dream come true ... Floyd Mayweather stepped into an MMA cage in what appears to be another attempt to bait the UFC star into another fight.

Floyd posted the footage on social media Tuesday -- one day after he took a shot at Conor for his #MCM ... which Floyd dubbed, "Mayweather Crushes McGregor."

Both Conor and Floyd made a killing off their superfight in 2017 -- but McGregor says he wants his next fight to be in the octagon.

So, how would that go? Oscar De La Hoya just told us the other day Floyd wouldn't last 10 seconds with The Notorious.

But we'd all probably pay to see it anyway ... and Floyd knows it.
