UFC legend Georges St-Pierre tells TMZ Sports he's training as if he WILL fight at UFC 206 in December ... and says Dana White needs to call his agent and book a match already!

GSP was at the "Kickboxer: Vengeance" premiere in Westwood Wednesday night -- and made it clear, he wants to return to the Octagon in a bad way.

"I wanna be [at UFC 206], but it's not my decision," St-Pierre said ... "I'm a phone call away."

GSP says he'll fight ANYONE -- from Tyron Woodley to Nick Diaz -- "If it's something people wanna see, no problem. I'll do it."

The 35-year-old says he's so laser-focused on fighting, he's turned down other opportunities outside the Octagon to train. He's even been sparring.

Nate Diaz is done playing games when it comes to marijuana -- posting a big bag of weed on Snapchat Wednesday night ... with his own name written on the bag.

Our in-house weed specialists (surprise, we got those) tell us ... it appears to be about an ounce of high quality bud ... which usually runs the average pot-smoker about $225.

CM Punk GUARANTEES he's gonna beat Mickey Gall's ass at UFC 203 ... and says he might just bust out one of his famous WWE wrestling moves to get the job done!!

CM Punk says he's not worried about embarrassing himself during his UFC debut ... because he once crapped himself during a WWE match ... so, how much worse could it be??

The 37-year-old is gearing up for his MMA debut at UFC 203 on Sept. 10th ... and was asked if he's nervous.

"It's funny because you can ask yourself, 'What happens if I lose? What happens if I get embarrassed in front of the world?'"

"And then you think to yourself, 'Well, you s**t yourself on national television before so how bad can it go? How bad could it really be?'"

FYI, the incident Punk's talking about went down in 2013 -- when Punk gave WWE fans a little more than they bargained for during a bout with Dean Ambrose.

Hey, at least he won the match ...

Brock Lesnar is DONE in the UFC -- and will never fight in the Octagon ever again, despite his hopes for a comeback ... so says Alistair Overeem.

Overeem is one of the few guys who actually beat Lesnar during his MMA career -- so when we saw him at LAX, we asked if there was a chance we'd ever see a rematch.

Problem is ... according to Alistair, we'll never see another Brock match, period -- following the drug allegations surrounding UFC 200.

You can see in the video Alistair has A LOT more he wants to say ... but bites his tongue.

It's interesting considering we just got Brock out earlier this month and he told us a UFC return was still a possibility.

We'll see ...

Paige VanZant knows not the ways of the evil Cobra Kai ... or how to properly wax a car ... because SHE'S NEVER SEEN 'KARATE KID!'

So, we were talking with Paige about her insane K.O. crane kick to Bec Rawlings' face at "UFC Fight Night" in Vancouver this weekend ... when she dropped the revelation.

"To be competely honest, and I'm gonna be judged as a martial artist, I've never seen 'The Karate Kid,'" Paige said.

"I need to go watch that."

Check out the clip ... Paige also shows off her black eye ... THE SAME BLACK EYE DANIEL LARUSSO HAD AT THE BEGINNING OF THE MOVIE!

"You're the best ... around!"

The Diaz brothers were playing with fire Sunday night -- hanging backstage at a Snoop concert ... with Nate holding (what appears to be) one of the BIGGEST JOINTS EVER!

It takes 60 HOURS and thousands of dollars to make every single custom suit for Conor McGregor ... and the guy has DOZENS of 'em ... so says his personal custom suit guy (yeah, he's got one).

We spoke to the UFC guy's longtime wardrobe guru David Heil -- CEO of David August clothing -- who says McGregor is an animal when it comes to fashion.

Here's the math -- each custom suit ranges from $4,000 to $10,000 ... and Conor orders 8 to 10 outfits every single time he goes out on a media tour.

"We also have 2 or 3 extra outfits on hand in case anything happens to the outfits he’s supposed to wear for an event."

Translation -- money is no object when it comes to Conor's look.

And Heil says he's a full-service outfitter -- "From the suits down to the bow ties to the cuff links, he’s wearing David August."

"Every outfit I make for him takes 60 hours. He likes to wear his suits high and tight and really tailored, and his size changes all the time depending on his fights. So we’re always measuring him to make sure it fits exactly how he wants it."

"He’s such a style guy ... he’s always been that way since the day I met him. He takes everything and makes it his own. It takes a guy with the right mind to pull off these extreme looks, and he does."

UFC ring announcer Bruce Buffer is going to bat for his boy, Casper Smart -- asking Jennifer Lopez to give him a pass for blowing off a NY fundraiser to be Octagon-side at UFC 202.

"He's a f***ing maniac, he's an animal, he's a competitor, he wants to win. That's his nature and I respect it." -- Dana White on Vince McMahon.

The UFC honcho opened up about his working relationship with the WWE tycoon on Ric Flair's podcast this week ... and while he says it hasn't always been smooth sailing, it's obvious he respects the guy.

"Vince has been very difficult in the past but the past several years he's been much better," White said.

White says working with the WWE on the recent deal that allowed Brock Lesnar to fight at UFC 200 -- along with a deal to get Ronda Rousey at WrestleMania 31 -- were "probably the best experiences."

"If you look at what Vince McMahon has accomplished in all of his years and to still be on top and still be doing it ... The guy's got enough money, he's in it because he loves it, he's in it because he's still passionate about it." White said.

Secret's out ... Demi Lovato is dating UFC superstar Luke Rockhold -- and TMZ Sports has learned it's a romance that's been blooming for a couple months.

Our sources tell us ... the 24-year-old singer hit it off with the 31-year-old former UFC middleweight champ earlier this year while training at Unbreakable gym in Los Angeles.

Long story short ... we're told the two clicked right away -- and have even sent some secret inside messages to each other on social media ... including a back and forth with smiley face art on their fingers.

Congrats!

Jennifer Lopez broke up with Casper Smart because he snubbed her by passing on a fancy Hamptons charity event in favor of hanging with his boyz at UFC 202 ... TMZ has learned.

Sources connected with the former couple tell us ... J Lo told Casper it was super important for him to accompany her to Ron Perelman's Hamptons fundraiser Saturday night benefiting the Apollo Theater.

Casper wasn't having it, because he desperately wanted to watch the Conor McGregor/Nate Diaz fight in Vegas with his friends.

Casper had a great time in Vegas, hanging with Kanye and UFC announcer Bruce Buffer.

J Lo, we're told, was enraged and ended the relationship ... no discussion -- simply, we're done.

Here's the funny thing ... Casper was telling people at the fight he was going to NYC Sunday to meet up with Jennifer, who was there filming a show. He had no idea being a no-show Saturday would end things.

Our sources add this ... J Lo and Casper have "broken up" several times before and gotten back together, and they say they would not be surprised at all if it happens again.

J Lo doesn't look like she's too broken up about it at the moment, though ... she was still in New York this morning looking perky as ever.

Nick Diaz ended up in the middle of a huge brawl while partying at Hyde nightclub in Vegas early Wednesday morning ... TMZ Sports has learned.

A rep for the club tells us the UFC fighter went to a bathroom outside the club around 2:30 AM, and accidentally stumbled into another customer ... who started talking smack.

UFC superstar Paige VanZant says she's on such good terms with Ronda Rousey after their heated encounter earlier this year ... she's decided to read her book ... and LIKES IT.

As we previously reported, Rousey confronted Paige at an event in L.A. back in April -- and cussed her out for congratulating Holly Holm on her victory at UFC 197.

VanZant says it's all water under the bridge -- "we're cool actually" -- and says she's learning a lot about Rousey in her book, "My Fight/Your Fight."

"It's really good and it's cool to kinda get inside and see the things that she's gone through that are similar to me," Paige said ... "So yeah ... no worries there."

Paige is gearing up to fight Bec Rawlings at UFC Fight Night in Vancouver on Saturday -- and essentially guarantees victory.

What happens when you get to your cageside seats at UFC 202 -- and Mike Tyson's sitting in 'em???

That's the question Kanye West had to ask himself when that happened to him at the Conor McGregor vs. Nate Diaz fight in Vegas this past weekend.

FS1's Skip Bayless says he saw the entire thing go down -- because he was sitting right behind Kanye's reserved seats.

But what transpired wasn't a fistfight ... one of the stars backed off in a big way -- and it wasn't who you think it would be.

Nate Diaz gave an upstart vape pen company a HUGE BOOST when he lit up after UFC 202, and now the biz is struggling to meet the high demand.

Tru Vape Oil's founder, Derek Hodslo, says his phone and computer haven't stopped blowin' up since Nate puffed on one of his pens at Saturday night's news conference. He says the endorsement was totally unplanned and, in fact, Nate caught 'em off guard.

He says they had no time to stock up on the cannabidiol (CBD oil) which Nate was using that night -- and also shouted out on Instagram. Hodslo estimates they could've shipped 20,000 units, but they only had 506 CBD cartridges in stock.

Still, he says the publicity is invaluable and will eventually pay off -- even if they're not getting rich quick.

As for Nate catching heat from USADA for smoking CBD -- he says it helps him deal with post-fight inflammation -- Hodslo is team Diaz all the way, standing by his product's healing properties.
