UFC

Floyd Mayweather needs to chill using the race card on Conor McGregor ... that's according to UFC announcer Bruce Buffer. McGregor's the man in UFC because he kicks ass ... not 'cause he's white.

Bruce was leaving Gold's Gym in Venice when we asked him about Floyd saying McGregor getting a pass from fans and media for his smack talk ... because he's white.

Floyd Mayweather says UFC champ Conor McGregor can be as brash and arrogant as he wants without catching any heat ... because of the color of his skin.

Mayweather did an interview with the guys over at FightHype.com last week, and when the subject of the flamboyant McGregor came up ... Mayweather went off.

"He talks a lot trash and people praise him for it, but when I did it, they say I'm cocky and arrogant. So biased."

He goes on to say ... "I ain't racist at all, but I'm telling you racism still exists."

Floyd then brings Ronda Rousey and Laila Ali into it ... questioning why Laila didn't get the endorsement and movie love Ronda does ... even though he feels Ali accomplished more.

How does a guy who bashes people's faces in for a living bond with his family over the holidays?

If you're UFC superstar Anderson Silva ... SIMULATED WARFARE!!!

Silva -- currently training for a big fight against Michael Bisping on Feb 27 -- took 12 family members out to Hollywood Sports in Bellflower, CA this past Saturday for some yuletide paintballin' fun.

We spoke with the owner of HS ... who tells us Anderson is a frequent visitor and believes the time shooting at each others heads promotes family unity ... and helps work off all that turkey.

How hardcore is Silva about his paintball? We're told he owns his own custom-made military grade tactical gear ... and loves to compete on the "Saving Private Ryan" battle course.

Still ... he's one of the only guys we can think of who's more dangerous WITHOUT a gun.

Conor McGregor is starting to upgrade ... rollin' around Santa Monica in a $500,000 CAR!!!!

Check out out the footage of the Notorious One ... doing some Christmas shopping in his Rolls-Royce Phantom Drophead Coupe ... while bumping old school Mariah Carey.

Don't judge him. Old school Mariah is dope.

As for the whip, it's just a drop in the bucket if you consider the fact UFC boss Lorenzo Fertitta just came out and said he expects Conor to be the UFC's first $100 MILLION fighter.

Talk about living up to your nickname ...

UFC superstar Ryan "Darth" Bader (get it?) says he'd kick the living snot out of a Jedi in a street fight ... and he's even got a strategy to do it.

The clip is pretty funny ... especially since "Darth" says he's not even a real 'Star Wars' fan -- he just liked the nickname better than the other option, "Master" (get it?).

UFC superstar Anthony "Rumble" Johnson says he's THRILLED that hated pharmaceutical exec Martin Shkreli has been arrested ... calling the guy a "scumbag" ... and saying karma's a bitch.

FYI -- Shkreli was busted by the FBI for securities fraud ... but he's most hated for jacking up the price on an HIV/cancer treatment because he's a greedy jackhole.

So, how does Rumble feel about it?

"He's a scumbag. Everything that is about to happen to him, should happen to him. God doesn't like ugly and he ain't pretty."

BTW, Johnson is fighting Ryan Bader at UFC Fight Night in January -- but before he took on pro athletes, he battled drunks as a bouncer!!!

He's got some CRAZY stories -- including the first time he got in a bar fight ... check out the clip.

Conor McGregor's movie career is officially ON -- 'cause we're told the UFC's 13 second knockout king has agreed to a role in the new 'xXx' movie.

The Irish superstar has said that Hollywood has been knocking on his door for a while -- and Vin Diesel is a huge fan when it comes to putting fighters in his flicks (like Ronda Rousey in "Furious 7").

In fact, Diesel posted on Instagram Monday suggesting Conor was on board for "xXx: The Return of Xander Cage."

Now, our sources connected to the situation tell us ... Conor HAS verbally agreed to play a role in the flick -- though it's unclear how big of a part it will be.

Of course, things happen in Hollywood and Conor could always pull out -- but for now, we're told it's a go.

As we previously reported, Mark Wahlberg is also interested in the Notorious one for an upcoming project.

Mr. McGregor ... you ready for your close-up?

Mark Wahlberg says the UFC fighter could be a GREAT actor -- if he gets the right role -- and tells TMZ Sports he's already considering Conor for a role in one of his many many MANY projects.

The Irish Consulate in San Francisco is charged with promoting Irish interests in the Western United States ... and Saturday night, those interests were trolling Jose Aldo and preventing hangovers.

In fact, just minutes after Conor McGregor knocked out Aldo at UFC 194 -- the I.C. in S.F. went to Twitter with a special message for all of the hard partying Irish fans who made it out for the fight.

BTW, earlier in the week, the Consulate sent out info about a 12 bar pub crawl in Vegas for all the visitors (for charity).

Ronda Rousey's the belle of the Marine Corps Ball -- arriving to the big bash in South Carolina moments ago ... to keep her promise to Lance Corporal Jarrod Haschert.

Ronda flew out early Friday morning -- and to be honest, still seemed pretty down in the dumps nearly one month after losing to Holly Holm.

But she was all smiles at the ball -- posing for pics with the marines and their dates -- and hopefully, enjoying herself.

Ronda's gonna need to get her mojo back if she's gonna have a chance to beat Holm in the rematch -- and who better to help reclaim her swagger than a buncha devil dogs, right?!?

Oorah!

Gotta love the Irish -- who invaded a UFC event in Vegas today and turned a Q&A with Holly Holm into a CRAZY sing-a-long ... with the entire arena joining in!

It all went down at the MGM in Vegas -- where the champ was taking questions from the crowd ... which seemed like it consisted of the entire country of Ireland (in town to support Conor McGregor).

UFC honcho Dana White is a hardcore supporter of Donald Trump and he can't wait to get to the ballot box.

Dana -- one of the most powerful people in sports -- made no bones about it ... he's Trump all the way, and he has his reasons.

Paige VanZant was in pretty good spirits Thursday night ... despite the beating she took from Rose Namajunas at UFC Fight Night -- smiling and laughing through the pain at her news conference.

The UFC star fought her ass off ... but in the end, Rose was just too much for the 21-year-old.

Afterward, VanZant kept a positive attitude -- though admitted," I wanted to win ... I'm sad, but I'm fine."

As for the winner, Rose was also smiling after the fight ... with barely a scratch on her body.

Trump may hate her guts ... but Bernie Sanders says he's still got Ronda Rousey's back -- telling TMZ Sports he's rooting for her to get back to DOMINATING people ASAP!!!

The presidential candidate was out in D.C. when we asked if he had any advice for the UFC star -- who happens to be one of Bernie's biggest fans.

Finally, Ronda Rousey is SMILING AGAIN!!!

For the first time since the beatdown in Australia, the UFC superstar was out in public looking like her old self -- happy and care free ... walking her dog at a park in L.A.

But did you notice the guy she was talking to? That's Nick Cassavetes -- a Hollywood heavyweight who's also directing Ronda's next movie, "Road House."

The Iceman says he's officially throwing his support behind Jose Aldo in the big UFC war this weekend ... kinda.

To be honest, Chuck Liddell sounded a bit conflicted when we talked to him about UFC 194 -- telling TMZ Sports he loves the way Conor McGregor fights ... but says he's an Aldo fan at heart.

We asked if he thought McGregor is overrated -- and Chuck shot that down too ... saying, "Every time someone says that he comes out and shows 'em wrong."
