Ronda Rousey wore a real body suit Friday as she was out and about in L.A.

Ronda gave BF Travis Browne a big smooch, looking like her old self.

She's gotta love the reaction she got from the pics we posted from the S.I. modeling shoot, where her swimsuit was literally painted on.

David Spade won't be going to the newsstand for Ronda Rousey's Sports Illustrated spread ... because there are easier ways to look at hot chicks.

Our photog got David Friday at Craig's in West Hollywood ... and the he made it clear he's over magazines.

UFC champ Conor McGregor is under investigation by cops in Ireland for a gun related violation ... after he posted a pic of what appears to be himself with an automatic rifle.

Ronda Rousey's confidence is back to champion form, and TMZ Sports has the hard evidence -- Ronda sporting NOTHING but body paint on a Caribbean beach!

The ex-UFC champ is doing a photo shoot for S.I.'s upcoming Swimsuit Issue on Petite Martinique island, off the coast of Grenada. We checked, and what looks like a swimsuit ... is just paint.

As you can imagine, Ronda's shoot on a public beach drew plenty of attention ... hence these pics.

Former Ultimate Fighter champ Julianna Peña got into a bar brawl with a bunch of guys -- and it got so out of control ... blood was all over the place.

911 callers reported the bantamweight fighter and her trainer Josh Gow were taking on security guards at Zola's in Spokane on Dec. 20. The audio is pretty brutal ... you can actually hear the fight still going behind a caller who said, "They're wiping their bloody faces on the door."

According to cops, Peña and Gow had actually gotten into a fight at a different bar -- with 20 people throwing fists -- and then bolted to Zola's. Security there refused to let them in because it was past closing time.

Cops say Peña -- who won Ultimate Fighter 18 in 2013 -- lunged toward bouncers who were trying to keep them out. She allegedly busted out some MMA moves, kicking 2 of them in the groin.

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).
