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."

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 may have lost the fight, but he was a champ at Encore Beach Club at Night in Vegas Saturday after the awesome battle in the ring.

Conor took the mic and told the crowd, "It didn't turn out the way we wanted but we can still party like it did."

Truth be told, it was something of a victory for Conor to go 10 rounds with Floyd, and it's pretty clear the crowd also saw it that way.

Conor danced to Biggie's "Juicy" and Fat Joe's "All the Way Up."

Floyd Mayweather partied all night after his victory, and it got so wild cops had to come and calm things down.

The champ showed up at his strip club, Girl Collection, in Vegas at around 2:30 am Sunday in the sickest new Red Bugatti.

Floyd partied inside for 2 hours, then re-surfaced and dealt with Vegas cops who showed up for crowd control. They were so many people who wanted a piece of Floyd they were spilling into the streets.

There were hundreds of celebrities at T-Mobile in Vegas to watch Floyd Mayweather battle Conor McGregor, and all but one had nothing but praise.

David Charvet, Carl Frampton, Sharon Osbourne, Tony Robbins, Paul Mitchell, A-Rod, J-Lo and Andre Berto had nothing but good things to say about the 10-rounder.

The only criticism came from Big Boy ... and he was not alone in what he felt was lacking.

Floyd Mayweather’s bodyguards were so impressed with Conor McGregor after his epic throwdown with their boss ... they invited him out to Floyd's strip club!

We got Jizzy Mack and Greg after the fight ... about to hit up Girl Collection with the rest of The Money Team.

The Brixx Bros told TMZ Sports they had mad respect for how McGregor boxed ... so much they were down to have Conor come through to their after-party.

The only catch -- they say he'd still have to pay to get in.

McGregor's about to bank around $100 MIL for the fight ... so they figure $500 ain't no thang.

Playas in town for Mayweather vs. McGregor are blowin' their wads in a BIG way -- droppin' $30-40K on sex for the Vegas super-fight ... so says Don "Magic" Juan.

We got The Bishop -- a notorious ex-pimp who's also Snoop's spiritual adviser -- outside MGM Grand ... and he told us the ladies are charging BANK for their services this weekend.

"Floyd -- he draw them money-gettin' chicks .. they chargin' that paper for real."

As for how much ... Magic estimates about 15 RACKS for an overnight -- and even more for the VIP treatment.

Basically, Sin City's turned into Hookerpalooza ... and DMJ says it's even crazier than he thought it'd be.

"Ladies and playas and alcohol and partying -- all that go together. It's goin' down tonight!"

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?

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.

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.

A bunch of Irish fans of Conor McGregor fired off some F-bombs at Floyd Mayweather's children -- including his 14-year-old daughter -- screaming, "F*ck the Mayweathers."

It all went down right after the weigh-in at T-Mobile Arena in Las Vegas on Friday ... where Floyd's kids were hanging about 30 or 40 yards from a pack of rowdy Conor fans.

You can see Floyd's 17-year-old son, Koraun, in a camouflage TMT shirt mocking the McGregor fans while they yell at the kids, including 14-year-old Jirah, 16-year-old Zion and 17-year-old Iyanna. The kids seems to be enjoying the spectacle!

The fans eventually stopped cussing and flipping the bird -- and started chanting, "Stand up for the boys in green" ... while Koraun continued to dance.

There's a Johnny Manziel connection to the Mayweather vs. McGregor fight -- his fiancee is one of the Corona Girls!

TMZ Sports has learned ... Bre Tiesi (who happens to be a smokin' hot model) was tapped to don the legendary Corona outfit to work Friday's weigh-in festivities.

She did an excellent job!

No word if Johnny plans on heading to Vegas to attend the fight -- or if he's busy training for his NFL comeback.

One thing's for sure ... Bre looks goooood!!!

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.

Floyd Mayweather is already spending his new fortune -- dropping millions on a brand new red Bugatti, TMZ Sports has learned.

We spoke with Floyd's car guy, Obi Okeke -- aka Doctor Bugatti -- who tells us Floyd hit him up 2 days ago to purchase a "triple red" 2012 Bugatti Grand Sport Convertible.

Obi says the car is "one of one" -- and costs $3.3 MILLION!!

We're told Floyd wanted the car to make a splash on his way to the weigh in for the McGregor fight Friday afternoon.

Floyd's expecting to make around $300 MIL for the fight ... so, what's a couple mil on a new whip, right?
