Conor McGregor spent most of the time at his Mayweather fight after-party locked in a conversation with Irish soccer legend Robbie Keane.

So, when we saw Robbie in Bev Hills this week we had to ask -- what did you guys talk about?!

Keane wasn't down to spill all the tea -- but admitted they talked about "everything."

We asked about the nature of their friendship -- Keane said they're both from Dublin.

Bottom line -- Keane's a big fan and says Conor's "gonna do great things."

Andre Berto says he wants to cross over from boxing to the UFC ... and he's 100% serious about it.

TMZ Sports spoke with Berto about Conor's return to the Octagon after losing to Floyd Mayweather ... and A.B. says he's gunning to follow his buddy back to MMA.

"Tell Dana (White) to call me. I'll go to the UFC. I wanna be the first fighter ever to be a world champion in boxing and then go get a world title."

Frankie Delgado isn't quite the famous face he used to be, and cops had to step in when the former reality star tried to get through VIP at the Mayweather/McGregor fight.

The incident went down when the ex-'Hills' star tried breezing past security Saturday night outside the VIP entrance to T-Mobile Arena. Our law enforcement sources tell us Frankie tried to walk in without showing credentials, and ignored security's objections.

Witnesses tell us he never used the words, but his attitude reeked of "You know who I am."

A Las Vegas PD Sergeant stepped in to stop Frankie while security sorted out the matter. The tense moment was captured in this photo, and despite how it looks ... everything worked out for Frankie.

Someone eventually confirmed he was on the list, and he watched the fight from VIP.

Fun fact: Frankie's still A-list at huge events! We underestimated "The Hills."

Add O'Shea Jackson Jr. (aka Ice Cube's son) to the short list of people NOT impressed by the Mayweather vs. McGregor fight ... in fact, he says it was a Titanic-level disaster.

The "Straight Outta Compton" star may have been a little biased -- remember, his dad's BIG3 had to MOVE venues because of the fight.

LeBron James says Conor McGregor was "tough as a motherf**ker" during the Mayweather fight -- and joked there's no way in hell he coulda gone 10 rounds with TBE.

TMZ Sports was right outside the T-Mobile Arena when we spotted Bron and Cavs teammate J.R. Smith breaking down the fight.

LeBron: "You gotta respect [McGregor]."

Smith: "The thing is he came out strong in the beginning of every round. He burnt himself out."

LeBron: "You gotta respect him though because he ain't no boxer. Tough as a motherf**ker though."

Smith's retort was hilarious -- "Sh*t, give me $30 million! I'd be tough too for 30 minutes!"

LeBron: "I'm dropping in the 1st round. I ain't lasting 10."

Conor McGregor was feeling so good the day after the Mayweather fight, he strolled into a Vegas pool party ... and turned up with a bunch of hot chicks in bikinis.

Conor was welcomed into Encore Beach Club by a crowd of loyal Irish fans -- who didn't seem to give one crap that he lost. They chanted and danced and boozed. Conor loved it.

But it was the OTHER McGregor who stole the show -- Conor's older sister, Erin, a former competitive bodybuilder who's also done some fitness modeling.

Erin and her baby daddy, Terry, turned up with the rest of the McGregor clan.

You would too, if your brother just made $100 million.

Sorry, fight fans -- Floyd Mayweather is "officially done" ... meaning there's not gonna be a rematch with Conor McGregor -- so says his kid.

We spoke to Koraun after the fight ... and he confirmed that Floyd's hangin' up his gloves.

"No chance. No chance. No rematch," Koraun told TMZ Sports, when we asked if he might come back for another HUGE payday.

"Officially done. He's 40, gotta realize that. He's an old man."

Floyd's son says his dad's got a business to take care of too ... so he's happy retiring at 50-0.

FYI, Mayweather said the McGregor fight was his last one "for sure."

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.
