TMZ Sports spoke with the champ just days before the Octagon door closes behind Pena and Harrison in the UFC 316 co-main event in the Garden State ... and let's just say Julianna doesn't see the similarities between Kayla and Ronda.

"Ronda was such a phenom in the fact she was just able to take everybody out in 10 seconds or less," the Venezuelan Vixen said. "I know Kayla's manager [Ali Abdelaziz] said she's gonna be bigger than Ronda Rousey."

"Man, I'm feeling better than ever," Jake said. "This is going to be my breakout performance."

7:27 AM PT -- According to court documents obtained by TMZ Sports, BJ Penn's mom, Lorraine Shin, claims she's the 79-year-old at the center of the allegations against the MMA legend.

In the docs -- which were part of an application written by Shin for a restraining order against Penn -- Shin alleged Penn is suffering from a psychological disorder that's caused him to believe she "killed his family" and has "taken over his mother's identity."

Court records show a TRO was granted in the case -- and both parties are due to appear before a judge on June 10 to share their sides of the story.

Cops in Hawaii say MMA legend BJ Penn was arrested over the weekend not just once, but twice, over multiple incidents he had with a 79-year-old woman.

Fight night should be a breeze for Belal Muhammad ... 'cause the UFC welterweight champ says he regularly works out with dudes most dangerous than Jack Della Maddalena, his UFC 315 opp!

TMZ Sports spoke with the 36-year-old fighter ahead of Saturday's main event scrap ... and like a slugger on deck taking hacks with a donut on his bat, Belal says the actual fight will be easier than his time on the practice mats.

"When I look at the guys that I train with, I tell you, I'm training with the best striker in the world in Ignacio Bahamondes. And I strike with this guy every single day. Jack doesn't have striking that comes close to him. The grapplers that I train with, the guys that I'm sparring with every single day, they're better than Jack," Muhammad said.

Bo Nickal says he'll face the toughest test of his still-young MMA career Saturday when he steps into the Octagon vs. Reinier De Ridder ... a former 2-division world champ in ONE!

The 29-year-old 3x NCAA wrestling champ and undefeated MMA fighter is set to scrap with 34-year-old RDR ... and despite being the 13th-ranked Middleweight, Nickal says Ridder is actually underrated.

"I think that both of us would beat most of the top 15, and I think that this fight is way more than an unranked guy fighting number 13," Bo told TMZ Sports. "Whoever wins this fight will have a really nice path to challenging for the title and fighting the best guys in the world."

Ian Machado Garry is fighting Carlos Prates in the main event at UFC Fight Night on Saturday, but that doesn't mean his (very real) beef with rival Colby Covington has been squashed!

TMZ Sports caught up with the #7 ranked welterweight contender just days before his highly anticipated scrap ... and while we talked a bunch about Prates, we also asked about Chaos.

"There's a reason I've said it before and I'll say it again when that man [Covington] goes to bed and he closes his eyes, he fears me. He's never going to step into the Octagon with me and back it up and he knows why," Garry said.

"Good control, good everything and especially I push myself to keep staying in the fight," he said. "I'll give it an A because I would like to finish. I'm always looking for the finish, so next time, I'll fix these mistakes to be able to go out there and get the finish next time."
