How the hell did Daniel Cormier lose 1.2 pounds in 2 minutes??!?

Huge dump? Big puke? Quick sweat session??

That's the question everyone is asking after the UFC star miraculously made weight for his UFC 210 fight after a nearly missing the cut at the official weigh-in Friday morning.

Long story short ... Cormier weighed 206.2 at his initial weigh-in -- 1.2 pounds over weight.

He left the room and came back 2 minutes and 24 seconds later ... and somehow, weighed in at 205 exactly. The fight with "Rumble" Johnson is now official.

But everyone wants to know what changed in those 2 minutes. Some conspiracy theorists think he grabbed the towel that was shielding his naked body and pressed down to fool the scale.

For the record, event officials have called BS on that theory.

We've reached out to D.C. for answers. Stay tuned.

Forget Floyd, Conor McGregor had someone else on his mind this weekend -- his soon-to-be born child ... 'cause the UFC star and his girlfriend just had their official baby shower!

Conor and Dee Devlin were surrounded by their closest female friends and family members (it appears Conor and the fetus were the only boys present) for a fancy shindig in Dublin.

The baby is due in May and while Conor and Dee reportedly have a name picked out, they're keeping it a secret until the birth!

Think Floyd will send a baby gift?

WWE star Baron Corbin would send Conor McGregor's ass to the hospital if the beefing stars actually fought ... according to WWE legend Taz.

Maybe Chris Weidman knows something we don't ... but the UFC star says the highly anticipated Floyd Mayweather vs. Conor McGregor fight is "100%" going down.

Weidman appeared on "MMA Report with Mike 'Gunz' Gunzelman" and said his information about the fight is "a fact."

Of course, Dana White has disagreed the last few times we've seen him out -- while he's said he wants the fight to happen, the UFC honcho has said the 2 sides are insanely far apart when it comes to money. But maybe something's changed.

Still, Weidman seems very confident and explained why he truly believes Mayweather could be in for a VERY painful night.

If Jon Jones beats Daniel Cormier, he'll solidify his spot as the greatest UFC fighter of all time ... above Anderson Silva ... so says Alan Jouban.

In fact, Jouban says Jones already has a more impressive resume than Silva.

"When you look at the guy that Jon Jones has beat in comparison to the guys that Anderson Silva has beat, Jon Jones has beaten way tougher guys."

Jon's top victories include ... Daniel Cormier, Glover Teixeira, Vitor Belfort, Rashad Evans, Lyoto Machida, Rampage Jackson and Shogun Rua.

Silva's top victories include ... Stephan Bonnar, Vitor Belfort, Forrest Griffin, Rich Franklin and Dan Henderson.

Bottom line ... Jouban says he wants to see Jones stay clean and compete for a long, long time.

WWE superstar Baron Corbin hasn't forgotten all of the trash Conor McGregor talked about wrestlers ... and says he wants a shot at the UFC star in the hopes of teaching him a very violent lesson.

Corbin -- who's wrestling for the WWE intercontinental belt at WrestleMania 33 this weekend -- appeared on 105.3 The Fan in Dallas when he was asked about Conor vs. Floyd.

After siding with Mayweather, Corbin brought up the comments McGregor made back in August ... when he said most WWE guys are "messed up p**sies" who couldn't hold their own in a real fight.

Corbin -- a former boxer and NFL lineman  --- clearly took the comments personally, saying, "I would like to slam him on his head a few times."

Vince, Dana ... thoughts?

The Floyd Mayweather vs. Conor McGregor superfight WILL happen ... as soon as Conor makes it happen, this according to one of Floyd's closest "friends" (who he used to bang).

TMZ Sports talked to Bad Medina, the woman who Floyd began dating right after his relationship with Ms. Jackson (remember her?) ended a couple years ago.

Medina says she and Floyd are more like close friends now, but claims she's heard him talk about the fight with Conor, and insists Floyd's all in, once McGregor actually gets serious.

Nick Diaz just got verbally SMACKED by an ex-boxing champ who says Diaz is nothing more than a coward from a redneck city (sorry, Stockton) who's afraid to fight a real pugilist.

The boxing great is Jean Pascal, former WBC, IBO, and The Ring magazine light heavyweight champ, who says he's sick of UFC guys claiming they can hang with REAL boxers.

Pascal ALSO says he's got a real problem with the way Nick trashed his buddy, GSP, before they fought back in 2013 and thinks Nick needs to be taught a lesson in humility.

You gotta check out the video ... the guy GOES OFF. Question now is, will Diaz respond?

Arianny Celeste is vacationing in Mexico ... and it looks like tops are optional at her beach of choice.

The UFC Octagon Girl and model let her girls free while enjoying the sunshine in Tulum ... and one of her friends even joined her.

And yes ... the buns were also out.

BIG WIN for Conor McGregor ... the UFC star got his big $75,000 fine reduced to $25,000 for that water bottle fight with Nate Diaz at the UFC 202 presser.

Remember, the Nevada State Athletic Commission hit McGregor with the massive fine -- plus 50 hours of community service. Conor was PISSED!!! So was Dana White.

But the Commission granted McGregor a rehearing which took place moments ago ... and agreed to REDUCE the punishment to a $25k fine plus 25 hours of community service, per Damon Martin of FOX Sports. He has 6 months to complete the community service.

Dana White ain't exactly saying "never" when it comes to Greg Hardy possibly fighting in the UFC ... but the ex-NFL star has to prove himself in some "serious fights" before he gets a look.

Hardy -- who was a beast in the NFL -- has transitioned into MMA and vows to be a real deal fighter ... with hopes of one day competing in the Octagon.

White warns that athletes who come from other sports often get WRECKED when they try to fight ... since most successful MMA fighters have been training for combat since they were kids.

Conor McGregor must be high as a kite if he thinks he deserves equal pay to fight Floyd Mayweather ... so says "Love & Hip Hop: Hollywood" star Jason Lee ... an unofficial member of The Money Team.

We got Jason Saturday at Toast in L.A., and he made it clear Floyd's ready to fight ... but that Conor's holding things up over ridiculous money demands.

Jason also has a dismal outlook on the future of boxing.

Ronda Rousey had a blast shooting her episode on "Blindspot"and wants to continue her role on the show into next season ... this according to Ronda and Dana White.

We spoke (briefly) with the UFC legend -- who shot her scenes for the NBC show 2 weeks ago -- and she tells us, "Blindspot was awesome. I really loved it. I hope I get to go back."

Pierce Brosnan is ALL ABOUT the Fighting Irish on St. Paddy's Day ... telling TMZ Sports his fellow countryman, Conor McGregor, will DESTROY Floyd Mayweather if they actually square up.

Dana White says Conor vs. Floyd is still a real possibility -- telling TMZ Sports, "It doesn't make a lot of sense for my business, but I would never keep Conor from making that kind of money."

The UFC boss was out in Bev Hills when he laid out Conor's opportunities ... some real big fights. He also said Conor's waiting for his kid to be born before he fights again.
