Conor McGregor's next fight will be in the OCTAGON -- so says Dana White, who tells TMZ Sports the Irish superstar is 100% going back to the UFC to "do what we do."

We spoke with White minutes after Mayweather racked up victory #50 over Conor on Saturday -- and Dana said he couldn't be more proud of the 29-year-old fighting sensation.

"That kid went out there tonight, 0-0 in boxing ... and went 10 rounds with the best to ever do it."

White says he's not sure who Conor will fight next in the UFC -- but he's certain there will be no follow-up boxing match for Conor.

Dana's not worried about Conor going Hollywood either -- "I don't know about movies. He's a fighter, not a movie star."

Ever wonder what happens when UFC champions randomly bump into the guys they've been calling out?

That's exactly what happened to Tyron Woodley on his recent trip to Vegas ... when a visit to Freddie Roach's boxing gym turned into a random meeting with Georges St-Pierre!

You know -- the same Georges St-Pierre that T-Wood said is "scared" to fight him.

Our photog figured Tyron and GSP would've thrown hands ... but Tyron told us they were too busy breaking down Georges' upcoming fight with Michael Bisping.

Woodley's a UFC analyst on FS1 -- and GSP's a crazy nice dude (even for a Canadian) -- so we're not too surprised that's how it went down.

A Stipe Miocic vs. Jon Jones superfight ain't on the table anymore ... but was it ever??

We spoke to the heavyweight champ on the heels of Jon's failed steroids test ... and Stipe says he hadn't heard of a potential matchup with Jones till Dana White mentioned it to reporters.

"I had no idea. I was like, 'That's news to me,'" Miocic told TMZ Sports.

Stipe's not ruling out a fight with Jones down the road -- but with JJ sidelined for who knows how long, he says he's looking to pull a Conor McGregor ... and fight heavyweight boxing champ Anthony Joshua!

Stipe would be a BIG underdog, just like Conor was against Floyd Mayweather ... but tells us he can hang with Joshua, no problem.

Dude was a Golden Gloves champ ... so never say never.

Conor McGregor made his last chance to trash Floyd Mayweather count ... and now we know EXACTLY what Conor was dishin’ out at Friday's face-off.

Spoiler – he calls Floyd a bitch. A lot.

In between, McGregor disses Mayweather by saying he's “soft, little, short, weak” ... and in the worst shape of his career.

Floyd looked good to us ... but Conor won the battle of the bods below the belt.

We’ve seen chill Conor talk trash. Now we’ve seen crazy Conor do it.

Both are pretty great -- but which one will we see tonight?

Conor McGregor beating Floyd Mayweather would be the biggest upset EVER ... this according to the man responsible for the most shocking upset in boxing history.

We talked to Buster Douglas with MayMac about to go down ... and he told us that Conor taking out Floyd would be waaay crazier than him KO'ing Mike Tyson back in 1990.

"I think his odds are a lot more tougher than mine," Buster told TMZ Sports.

"Conor is no boxer ... he has no boxing skills."

Buster says Conor's only shot is hitting Floyd with a "Hail Mary punch" -- but he expects Floyd to flat-out dominate.

FYI, Douglas was a 42-to-1 underdog when he knocked Tyson out.

Right now, Conor's about a 4-to-1 dog ... but over 90 PERCENT of bets are being put on him to upset.

Welcome to the Roast of Oscar De La Hoya ... hosted by Dana White!!

The UFC honcho is tearing Oscar a new one over comments DLH made this week on the "TMZ Sports" TV show on FS1.

Long story short ... Oscar tried to downplay his interest in a possible Conor vs. Canelo Alvarez match -- and Dana White wasn't having it. At all.

"He's WAYYYY down with that," Dana said ... "Don't feed into his bullsh*t."

And that's when White just began to unload on Oscar ... saying he used to be cool with the boxing legend until he began to publicly trash the Mayweather fight. Dana basically says the guy is two-faced.

What ensues is an expletive-filled rant about the Golden Boy ... and it's pretty hilarious -- unless you're Oscar.

Floyd Mayweather will be staring down several racks of cash hours after the fight with Conor McGregor -- win or lose -- 'cause clubs are throwing big bucks to get him to show his mug Saturday night.

TMZ Sports spoke with several Vegas promoters and the numbers are insane. One of them told us he'll pay Floyd $30k just to walk through his establishment ... for only 10 minutes! Another doubled that, offering $60k for a 30-minute pool party appearance on Sunday.

Sources close to Floyd tell us he already has 3 other offers -- for $50k, $80k and $100k. We're told the offers would still stand even if he loses because people would still want to chat him up.

Unfortunately for all those promoters, Floyd hasn't agreed to any of it. But we're told he WILL make some appearances besides his Girl Collection strip club party. If he accepts everything on the table -- which is logistically possible -- he could pocket a total of $320,000.

UFC star Kevin Lee says Conor McGregor's gonna have to go coffin shopping if they ever square off ... 'cause he's comin' for the Notorious' belt after UFC 216 ... and says it ain't gonna be pretty.

TMZ Sports spoke with Lee about his plans after taking on Tony Ferguson for the interim lightweight title -- which he sees as the hardest fight in the division, not Conor.

The Motown Phenom says he's been doing all of Conor's hard work -- which makes him the REAL champ -- and he's not afraid to take on McGregor.

Lee makes his point clear by saying if he were to cross paths with Conor in the gym, he'd be in serious trouble:

Lookin' to make some extra cash during the Floyd vs. Conor fight?? BET ON THE BOOBS ... 'cause Demi Lovato's twins highlight the fight's list of prop bets!!

The cyber-gambling site BetOnline.ag -- one of the biggest gambling sites on the net -- is offering up a bet on whether Demi will show cleavage or cover up the goods during "The Star-Spangled Banner" before the fight.

As of right now ... the odds are definitely pro-boob:

Yes +350 (bet $100 to win $350)

No -500 (bet $500 to win $100)

There's more (not as sexy) bets ... like over/under 1 min 52 seconds for her rendition of the anthem and whether the Biebs and Lil Wayne will make an appearance.

Dominick Cruz is shutting up all the Mayweather vs. McGregor haters at the 11th hour ... saying MayMac is gonna spark an "amazing" change for the UFC and boxing.

MORE SUPERFIGHTS!!

Dom admits a Conor win would be best for UFC superstars like himself ... but tells TMZ Sports we should expect a lot of crossover in the fight game no matter the outcome.

"Either way, this fight is gonna create that type of chemistry between the two combat sports," Cruz said. "I think we're gonna see more superfights from here."

One catch -- Dom told us it's just gonna be MMA fighters trying boxing cause, "I don't think any boxer on Earth is that dumb to come over to us."

Burn.

Conor McGregor was VERY excited about the weigh ... at least judging by the bulge in his pants.

The UFC superstar weighed in at 153 pounds ... while parts of him were hanging off the scale.

Floyd weighed in at 149.5 ... some room to grow.

Congrats to Calvin Klein, the maker of McGregor's underwear, for containing the beast.

Irish eyes are smiling.

Floyd and Conor now have just one date left -- when they square off in Vegas on Saturday night for the super fight.

Ronda Rousey won't be ringside for McGregor vs. Mayweather ... 'CAUSE SHE'LL BE GETTING MARRIED!

Dana White revealed that Ronda will be tying the knot with longtime boyfriend Travis Browne on Saturday. The two got engaged back in April.

White told Rich Eisen he was invited to the wedding but obviously won't be able to attend. Ronda previously announced on "Kelly and Ryan" that the wedding will go down in Hawaii.

As for Ronda's career, Dana says she hasn't retired -- but says she's in a great place and super happy.

Tyron Woodley ain't convinced Jon Jones took steroids ... but if he did and has to sit out 4 YEARS, Tyron says Jon would still come back and DOMINATE.

That's right -- Woodley told us Jones is such a boss, he could reclaim his belt even if he's benched through his prime.

"Jon Jones is the only fighter on the roster that it wouldn't be over for him. He's 3 or 4 years ahead of the curb right now, for the (205 pound) division."

"After Daniel Cormier, tell me one fighter who's gonna compete with Jon Jones."

FYI, Dana White estimates Jones will get suspended for his test failure ... but JJ could serve less time (or no time) based on how his appeal goes.

Conor McGregor whispered some words of psychological warfare to Floyd Mayweather during their final face off on Wednesday ... and now we know exactly what he said.

Take a look ... Conor leans in and takes a few quiet, private shots at Floyd.

Floyd responds, "You're a comedian."

Despite the trash talk -- the two men exchange final pleasantries ... quietly wishing each other good luck.

And get this ... the UFC has released new footage from Conor's sparring sessions with Paulie Malignaggi showing the Irish superstar putting a beating on the former champ.

Paulie is now saying he was spying for Floyd the entire time. Hard to spy from the canvas though.

Floyd Mayweather just stepped up the mind games big-time with Conor McGregor -- claiming he and Paulie Malignaggi plotted to have Paulie spy on Conor's camp from the beginning!

"Paulie has always been my friend," Mayweather told FightHype.com ... as Paulie paid a friendly visit to Floyd's Vegas boxing gym. That's when he revealed the spy plot ...

"My friend called me and said, ‘Floyd, do you want me to go to (Conor’s) camp?’ I said, ‘Abso-f*ckin’-lutely.' ... Paulie, thank you for going over there like I asked you to do."

As Floyd talks, Paulie repeatedly says "suckas" -- a shot at McGregor ... and maybe the public for being duped.

Remember ... Paulie was brought into Conor's camp to be a sparring partner -- but bounced after training footage he said made him look bad got released.

Now ... Floyd's saying Paulie's been in his corner all along -- and that his boy is gonna tell him all about Conor's game plan.

“Me and Paulie gonna stay at the house and talk about strategy, we gonna talk about EVERYTHING."

Is he joking? Maybe. Maybe not.

Dana White says he REALLY hopes Jon Jones' positive drug test is a mistake and he'll be exonerated by the B sample ... but he says that's "highly unlikely."

White appeared on the "TMZ Sports" TV show (airs weeknights on FS1) and said he still hasn't personally spoken with Jones since he learned the UFC superstar tested positive for steroids.

White said he was disappointed in Jones -- since the guy is so insanely gifted, he doesn't need banned substances to dominate in the UFC.

"He doesn't need it!!!! He doesn't need to do that! He's that talented and that gifted that he doesn't need drugs."
