UFC

Here he is ... Conor McGregor Jr. ... and the kid is already killin' social media.

Conor McGregor posted the very first pic of his new baby early Sunday morning -- a kid with steely eyes and a tough lookin' jaw. Kid's got a big right arm, too.

He'll clearly destroy all other babies in the maternity ward.

The UFC superstar's girlfriend Dee Devlin looks great -- smiling with the kid at Coombe Maternity Hospital in Ireland, where the baby was born Friday night.

By the way, Conor Jr. is already proving to be a massive hit on social media -- with more than 40,000 followers on Instagram in the first 48 hours of his life.

Dana White says if Anderson Silva is even thinking about retiring he should DO IT ... 'cause the UFC simply ain't gonna give Silva the title shot he's asking for ... at least right now.

Earlier in the week Silva went public threatening to retire if he didn't get a shot at Yoel Romero for the interim middleweight championship.

When we got Dana out in Beverly Hills he had some advice for Silva ... get to steppin' ... telling our guy there's no way in hell Anderson is gonna get that shot.

If we're keeping it real, White seemed aggravated about the whole thing, making you wonder if Silva might've overplayed his hand a little.

A UFC champion is about to tell you how he made $16K pretending to be one of the greatest football players OF ALL TIME ... and you'll only hear it here on TMZ Sports.

We talked to Tyron Woodley who tells us he's been really hustling in his acting/stuntman career, and it paid off recently when he got to double NFL hall of famer, Barry Sanders, in a Pepsi Max spot.

Woodley -- who was in makeup for a project when he talked with us -- said he had to look like Barry, and walk like Barry, and do something Sanders didn't do much in his career ... fall down.

The whole thing took an hour ... and according to Tyron the going rate for four falls as Barry Sanders is a cool $16K.

Not bad work if you can get it ... but you can't.

Dana White says he's not sure if Nate Diaz or his brother Nick Diaz will ever fight in the UFC again -- telling TMZ Sports straight-up, "They don't seem like they wanna fight."

Dana says the UFC has offered multiple fights to both Diaz brothers but they keep turning them down -- and White says he's not really sure why.

"If they want to fight next week or if they never want to fight again, that's up to them. It's not up to me," White says.

"They don't seem like they wanna fight ... either one of them."

White also responded to incendiary comments Nate made on "The MMA Hour" on Wednesday about his rematch with Conor McGregor ... a fight Nate lost by decision.

"The decision went to him because the company wanted it to go to him," Nate said (around 15:30 in the YouTube clip).

White says the comments are nothing more than "crazy talk" -- because the UFC has nothing to do with the judges or their decisions.

Cody "No Love" Garbrandt may have to change his nickname ... 'cause he's engaged!

The UFC star popped the question to his girlfriend, Danny Pimsanguan, in Sedona, AZ on Wednesday -- and sealed the deal with a pretty solid diamond ring!

The undefeated bantamweight champ and Wet Republic model have been dating for over a year now -- and they seem to be inseparable based on their social media pages.

Danny posted on social media about the engagement saying, "I'm so happy! We're engaged!"

Cody called her the "future Mrs. Garbrandt."

Congrats!

Ex-UFC heavyweight champ Frank Mir tells TMZ Sports he will probably NOT fight the 2 year ban he just got from the USADA for a banned substance ... and will likely look to fight in another country instead.

The United States Anti-Doping Agency says Mir failed a drug test following his UFC Fight Night 85 bout with Mark Hunt and hit him with a retroactive 2 year ban that will end in about 11 months.

But 37-year-old Mir tells TMZ Sports he doesn't wanna wait around -- "I'll keep looking for ways to fight."

Could 5'3", 125 pound Demetrious Johnson beat up a massive NFL linebacker in a real-life bar fight???

That's what we asked the UFC flyweight champ ... and he had a pretty good idea how things would go down.

Here's the deal ... DJ is considered one of the greatest UFC fighters of all time -- but we really wanted to know if things got violent in the real world, does skill trump size and brute strength??

Arianny Celeste says she's super happy for Ronda Rousey -- congratulating the UFC legend on her recent engagement to Travis Browne.

Remember, Ronda and Arianny clashed during Ronda's fighting days -- but now, it appears it's all water under the bridge.

In fact, the UFC's most famous Octagon girl praised Ronda for paving the way for female fighters in the UFC and called on the fighting organization to do something special for its biggest star.

See ... what beef?

Tyron Woodley wants big fights -- and he's not afraid to name names ... telling TMZ Sports he wants a piece of Georges St-Pierre if he can't get Conor McGregor.

The UFC welterweight champ co-hosted the "TMZ Sports" TV show (airs Thursday night on FS1) -- and told us why he's lost respect for the great GSP.

By the way, Woodley is GREAT on the show tonight -- hitting everything from Ronda Rousey's engagement to the fight at the Royals game and even tells us why Vin Diesel "pulled up" on him at the "Guardians of the Galaxy Vol. 2" premiere this week.

Ronda Rousey is getting married!!!

The UFC superstar just revealed she's engaged to her UFC fighter boyfriend, Travis Browne -- who she's been dating since 2015.

Browne popped the question with a massive diamond ring -- and said he proposed under a waterfall in New Zealand about a week ago because "it felt like the right place to do it."

Ronda says she hopes the wedding will be soon -- but says she also doesn't know what goes into planning a wedding ... so, she's keeping an open mind about the date.

Congrats!!!

We reached out Dana White who says, "I'm very happy for Ronda and I'm looking forward to the wedding!"

Conor McGregor believes he'll walk away with more than $100 MILLION after his fight with Floyd Mayweather ... and says Dana White was just being conservative with his $75 million prediction.

White told us earlier this week he believes McGregor vs. Mayweather WILL happen -- and told Colin Cowherd that Conor should make around $75 mil and Floyd will get around $100 mil.

But Conor just weighed in on social media saying White's numbers are low.

"How's that 75milli make your stomach feel? It's actually 100+ milli if we go by the non conservative numbers the fight will actually do and that's not including my endorsements and business ventures."

He added, "28 years of age. Fresh c*nt. Doubt me now."

Remember, back in November, Conor called his shot -- saying he wanted $100 million for the fight.

Ask, and you might receive ...

There's more ... Conor also released some footage of him giving boxing advice to one of his proteges.

He explained that he's been focused on boxing lately but "make no mistakes, the kicking and grappling aspects, and everything else got to do with unlimited free fighting, is still very much present in my thoughts."

He also suggests that if Floyd bails on their superfight, he could convince Manny Pacquiao to take his place.

"Floyd may crap his jocks after all and if so I will go back to true fighting or just pick another boxer like manny or something. But whatever that's another conversation."

Cody Garbrandt says Demetrious Johnson better ice up ... 'cause he's coming for the UFC legend right after he smashes through T.J. Dillashaw.

Cody and TJ are set to square off at UFC 213 in July -- it will be Cody's first fight since winning the UFC bantamweight championship back in December. The two hate each other's guts and are coaching opposite each other on "The Ultimate Fighter 25" which premiers tonight on FS1.

But after they square off in the Octagon, Cody tells TMZ Sports he wants Mighty Mouse -- and says meeting DJ at the 125 pounds won't be a problem.

How's this for optimism ... Dana White says the Conor McGregor vs. Floyd Mayweather fight is now "probably going to happen" ... and he's focused on getting a deal done ASAP.

UFC superstar Demetrious Johnson says he's dead serious about a fight with Conor McGregor -- explaining that stepping up to The Notorious is his best chance of making a 7-figure payday.

Johnson just beat up Wilson Reis for his 10th title defense in a row -- but despite his UFC dominance, Demetrious still hasn't gotten that fat million dollar check.

Long story short, Mighty Mouse knows the road to riches is through Conor ... despite the significant weight difference.

Demetrious just fought at 125lbs. Conor's last fight was at 155.

DJ says he can't get all the way up to 155 -- but says he's confident the two sides could work something out ... and says it would be a much easier fight to make than Floyd Mayweather.

With Ronda Rousey's MMA career seemingly over, there's another rising female fighter who believes she can be the next great UFC superstar ... Rose Namajunas.

The 24-year-old face-basher joined the guys on the "TMZ Sports" TV show on FS1 after her impressive victory over Michelle Waterson this weekend ... and didn't shy away from the Rousey comparison.

While she's not super into making a career turn into acting, there is one side of Hollywood she'd like to infiltrate ... and she'd be damn good at it too.

Mayweather vs. McGregor ain't even close to happening ... so says Dana White.

With the UFC honcho recently vowing to try to make it happen, we asked Dana if there's been any movement -- but the answer ain't what we were hoping for.

Then again, we probably shouldn't expect much until after Conor's baby is born -- Dana has previously said they have plans to meet up after McGregor's girlfriend gives birth.

We also talked to White about Ronda Rousey -- and he reminds us that she hasn't officially retired yet.
