Great video of UFC superstar Amanda Nunes ... strollin' through the airport with her 2 favorite things -- her girlfriend and her CHAMPIONSHIP BELT!!!

Amanda and Nina Ansaroff landed at LAX following Nina's big victory at "UFC Fight Night" in Phoenix on Sunday ... and they were both still riding high off the win.

Nunes also told us she believes she can continue to destroy people like she did Ronda Rousey ... and prove to be even more dominant than Conor McGregor.

As for Ronda ... Nunes says she doesn't feel bad at all for the beatdown she put on the UFC superstar -- but says if Rousey wanted to talk things out, she's down to have a conversation.

BJ Penn should hang 'em up 'cause he's a shell of the dominant fighter he once was ... so says former UFC champion Frankie Edgar.

Penn, 38 years old, returned to the Octagon Sunday night after a 3 year layoff ... and was absolutely DESTROYED by up-and-coming star Yair Rodriguez ... igniting the debate, should BJ retire?

TMZ Sports talked to Edgar -- who fought and beat BJ 3 times -- about Penn's future in fighting.

Floyd Mayweather is spitting more venom at Dana White -- calling him a "small boss" who used to carry his bags back in the day.

Mayweather went off on the UFC honcho at the Barclays Center this weekend -- once again trashing Dana's $25 MILLION offer to fight Conor McGregor ... this time, he took a stroll down memory lane.

"Dana White ... he was a player. He was a boss ... but he was a small boss."

"I can remember Dana White used to hang around me and Jeff Mayweather and carry my bags."

Mayweather says he used to be cool with White until ... "all the sudden he cut his head bald and he's such a tough guy. He's such a tough guy."

Just a few days ago, Dana told TMZ Sports why Floyd would be a fool to shoot down the offer.

Hope Amanda Nunes hasn't gotten too attached to the UFC women's bantamweight title ... 'cause another female fighter says she's 100% taking it in 2017.

TMZ Sports talked to former 'Ultimate Fighter' winner Julianna Pena, who's currently ranked #3 in the division and set to face Valentina Shevchenko on Fox later this month.

It's clear Pena has more than just Valentina on her mind though, saying she's gonna conquer not only her next opponent, but the entire 135 class this year ... and that includes champ Amanda Nunes.

Ronda Rousey could have a golden opportunity to improve her stand-up fighting game -- because Floyd Mayweather says he's willing to work with her ... if she'll give him a chance.

We got Floyd leaving Pristine Jewelers in NYC (he dropped roughly $200k on gifts for family and friends) -- when he told us he has nothing against Ronda and would love to help her out.

"I'll work with her if she's willing to work with me," Floyd said.

Ronda has blasted Floyd in the past over his domestic violence conviction. Floyd fired back by saying he makes way more money than she does.

But now, Mayweather says it's water under the bridge for him ... and it's her call.

He just beat up one champion ... now Cody Garbrandt says he's ready to fight another -- Conor McGregor.

The UFC bantamweight champ was telling us about what fighters he'd like to take out next ... and the Irish superstar was right on the list ... next to Jose Aldo and T.J. Dillashaw.

Garbrandt just fought at 135 lbs and Conor has fought at 145, so they're not too far off.

Plus, they almost got into a brawl on "The Ultimate Fighter" back in 2015 ... and it seems like Cody's got some unfinished business.

Ex-wrestling superstar Alberto Del Rio says he's willing to risk deportation to voice his opinion about President-elect Donald Trump ... calling the guy a total "dumbass."

Floyd Mayweather is shooting down Dana White's $25 MILLION offer to fight Conor McGregor ... saying simply, "You're a f**king comedian!"

Earlier Friday, White appeared on 'The Herd' on FS1 and made the official offer for the fight -- $25 mil each plus part of the Pay-Per-View profits.

Floyd was clearly INSULTED by the offer and told us to look at his watch ... a limited edition Hublot Laferrari which usually starts around $220k and can run up to around $350k.

The message ... Dana's number is WAYYYY too low.

Back to the drawing board.

Dana White just made his first official offer to Floyd Mayweather to fight Conor McGregor ... $25 MILLION EACH ... plus a Pay-Per-View split.

White just made the offer on 'The Herd' on FS1 -- after Mayweather claimed to have offered Conor $15 million.

For the record, White says Floyd never officially made that offer ... but his offer to Floyd is REAL.

Dominick Cruz says even though he lost to Cody Garbrandt at UFC 207 ... he's still in his head, claiming the new champion can't get on with his life because Dominick is still haunting him.

Cruz co-hosted with the gang on the "TMZ Sports" TV Show and talked about his rivalry with Garbrandt ... one that you'd think would've ended after Cody got his hand raised.

Turns out Cody is still thinking about Cruz -- including when we saw him on the street in NYC today -- which Dominick says is because he knows no one cares about him without Cruz in the mix.

UFC champ Tyron Woodley says he REALLY does believe the Conor McGregor vs. Floyd Mayweather fight will happen ... but if it doesn't, he's willing to step in for a fraction of the price!

Woodley joined the guys on the "TMZ Sports" TV show (airs Wednesday night on FS1) -- and was pretty strong about why he believes the two sides will hammer out a deal.

Still, Tyron has a message for Floyd -- I'LL DO IT FOR $5 MIL AND SOME WATCHES!

The younger brother of UFC star BJ Penn was arrested Tuesday after a crazy incident on an airplane in which he allegedly yelled, "I won't get off the plane without a fight."

Reagan Penn -- a former MMA fighter himself -- was on a Delta plane at LAX headed to Phoenix to see his big brother throw down at UFC Fight Night 103 when he got into it with flight crew over alcohol.

We're told Penn wanted booze before takeoff, crew refused to serve him and an argument ensued. He was eventually told to deboard the plane but he refused.

Cops were called but the standoff continued -- and he allegedly told officers, "I won't get off the plane without a fight."

A witness tells us Penn commented that his brother would "kick his ass" if he didn't make it to PHX for the fight.

Penn was "taken down" by at least two officers who handcuffed him and arrested for him trespassing. He was taken to a nearby station where he was booked.

Penn has since been released. No word if he made it to PHX yet.

Floyd Mayweather says Ronda Rousey is still a legend and should keep her head up after her loss to Amanda Nunes ... telling the UFC star, "A true champion can bounce back."

Mayweather opened up about Rousey to FightHype.com -- saying people unfairly tried to pit him against Ronda in the past because of his 2010 domestic violence incident.

Mayweather denied beating his ex-girlfriend but says, "Am I guilty of restraining someone? Yes. I'm not perfect."

"God only made one thing perfect ... that's my boxing record."

Floyd then turned his focus back to Ronda -- encouraging her to get back in the Octagon and fight again.

"Stay focused ... go back to the drawing board."

Great news for Nick Diaz ... and other jocks who love weed -- the Nevada Athletic Commission is FINALLY considering removing marijuana as a banned substance ... TMZ Sports has learned.

Now that Nevada has legalized pot, the N.A.C. has plans to discuss the removal of cannabinoids from the Prohibited Substances list which affect all athletes who compete in the Silver State.

The N.A.C. is scheduled to discuss the matter on Friday -- and our sources tell us it's looking good for the pro-weed movement.

If the weed ban is overturned, we're told it would take at least 3 months before it goes into effect -- so, don't pick up the bong just yet.

Ronda Rousey is back on the grid ... kind of ... posting a quote on social media about bouncing back after hitting "rock bottom."

The UFC legend put up a J.K. Rowling quote that reads, "And so rock bottom became the solid foundation on which I rebuilt my life."

Rowling famously delivered the quote during a 2008 speech at Harvard while talking about how she wrote 'Harry Potter' while she was broke, jobless and recently divorced.

Rousey said she was a broken woman after the Holly Holm fight. She appeared to take the Amanda Nunes loss equally hard ... essentially going into hiding after UFC 207 to ponder her future.

Dana White says Meryl Streep is an "uppity 80-year-old lady" who was completely WRONG when she took a shot at MMA during the Golden Globes.

We spoke with the UFC honcho about Meryl's comments Sunday night -- when she was ripping Donald Trump's immigration plans and said if we kick out foreigners, "you'll have nothing to watch but football and mixed martial arts, which are not the arts."

White objects in a BIG WAY -- calling the dig at his sport "stupid" and "uneducated."

We also asked if he thought Meryl targeted MMA because Dana gave a speech for Trump at the Republican National Convention.
