MMA legend Tito Ortiz is no stranger to bad breakups ... and tells TMZ he's moved on from the UFC because he knows Dana White ain't lookin' to bury the hatchet anytime soon.

Dana and Tito famously trashed each other following Tito's last UFC fight back in 2012 ... and Ortiz has since struck a deal with Bellator, a rival MMA organization.

In fact, Ortiz is set to fight fellow UFC-defector Rampage Jackson under the Bellator banner in November.

But, when we asked Tito if there was any chance at patching things up with his former boss and returning to the UFC ... Tito simply explained, "Nah, Dana holds grudges."

It ain't the first time Tito and Dana have gone after each other -- they also tore each other apart back in 2008 ... and Tito left the UFC ... only to return one year later.

Tito Ortiz is scrambling to protect his reputation in the face of a public smear campaign ... helmed by his baby mama Jenna Jameson -- telling TMZ, whatever she's about to say on TV is bound to be filled with lies ... because she's a dirty liar.

FYI, Jenna recently sat for an interview with "Entertainment Tonight." It's unclear what the interview is about, but Tito's guessing he's a main talking point ... and given their sordid history, he probably isn't portrayed in the best light.

So he's coming out to clear his name preemptively -- telling us, "I want to make it very clear that any and all allegations she has made about our personal life and my character are completely false. Jenna continues to paint a picture of distorted reality, which has been hurtful to both myself and my family. I hold sole custody over our boys, which speaks for itself."

He adds, "I am moving on with our life and with our boys, and I pray this is all over soon. I wish Jenna would get help to not only save herself, but for the children she brought into this world."

He was a joke in "Street Fighter" ... he sucked in "Double Team" ... but Jean-Claude Van Damme could BEAT YOUR ASS in real life, so says UFC champ Georges St-Pierre.

A well-dressed GSP was out being a badass in NYC yesterday when we asked if he thought martial arts legend Bruce Lee would be able to dominate in today's UFC (c'mon, of course he would).

But Georges said the superfight he'd REALLY like to see is Van Damme vs. Chuck Norris -- "I think that would have been the best showdown."

GSP says he's trained with JC in the past and says the Muscles from Brussels is no joke when it comes to fighting (see: final scene from "Bloodsport").

Of course, Chuck Norris is kind of a badass too -- he once FOUGHT A BEAR!

Two years after UFC badass Brock Lesnar was forced to retire due to serious stomach issues, the Beast Incarnate proved his guts are still TOUGH AS HELL ... by woofing down enough food to feed a small Italian village.

As you may recall, Brock was diagnosed with a severe case of diverticulitis back in 2009 -- a digestive tract disease that usually forms in the large intestine -- and after multiple surgeries, he was forced to retire in 2011.

But things are lookin' up ... 'cause TMZ has learned Lesnar and his wife Sable hit up Fresco restaurant in Montclair, NJ on Monday ... and Brock put his belly to the test.

Check out what he ate:

-- Ahi tuna with asparagus (shared)
-- Margherita pizza (shared)
-- Chicken Parm ... with TRIPLE-EXTRA chicken
-- Full bowl of parpadelle bolognese

... and, to top things off, dude crushed a slice of cheesecake by himself.

We're told the entire meal cost just north of $500 ... PLUS, we're told the WWE star left a "very generous" tip to everyone who stayed past closing time to take care of him.

Awesome.

Newly-crowned UFC champ Chris Weidman says he's unstoppable -- telling TMZ, he destroyed UFC's reigning middleweight king Anderson Silva when no one else could ... and he's ready to do it again in a few months.

There's a lot of speculation that Silva succumbed to Weidman over the weekend because he's getting old and has lost his edge -- but Weidman's not buying it, telling us Silva was as strong as ever in the Octagon ... he just wasn't strong enough.

Sounds like fighting words to us ... which is good because Weidman and Silva are already set to rematch very soon.

Screw Disneyland ... after Chris Weidman delivered his KO punch to Anderson Silva, the new UFC champ took his fists straight to a Vegas club to reap the spoils of his victory.

The celebration went down at Surrender Nightclub inside the Wynn hotel. We're told Chris rolled in at 1:30 AM with a crew of about 40 people ... including NBA champs Mike Miller and Udonis Haslem.

He also brought his giant championship belt.

Some people said it couldnt be done ... but last night reigning UFC champ Anderson Silva LOST his first title fight in seven years ... when Chris Weidman knocked his ass out.

It all went down in Las Vegas as the MGM Grand Garden Arena. Chris and Silva faced off ... with Silva -- considered the best MMA fighter in the history of the sport -- defending his seven-year stronghold on the middleweight title.

But Silva was fighting cocky -- with his hands down -- and by the 2nd round it caught up to him ... when Weidman caught the Brazilian with a nasty left hook. Silva instantly went down and Weidman was crowned the new champ.

Ex-UFC champ Ricco Rodriguez has just dodged the strong arm of the law in his drunk driving arrest ... TMZ has learned.

The "Celebrity Rehab" Season 1 alum was arrested in March on suspicion of DUI.

Rico copped a deal, and pled no contest to "wet reckless" -- reckless driving involving alcohol. It's not as serious as DUI, but gets the point across. The DUI charges were dropped.

The former champ won't spend any time in the pokey, but he will be on probation for 3 years. And he was socked with the obligatory $300 fine and a 12-hour alcohol ed program.

Marcellus Wiley thinks 51-year-old Herschel Walker is CRAZY for thinking he can make an MMA comeback ... because as the old saying goes, "Father Time is undefeated."

Our photog spotted the former NFL star (and current ESPN Radio host) outside of Pink Taco this weekend. After first giving his blessing to Miley Cyrus and her burgeoning twerking career ... Wiley put the kibosh on Walker's fighting one.

As Wiley put it, "Let it go. I would hate to see Herschel Walker make it through all he's been through and now get crushed in UFC."

But Wiley did say HE could dominate the UFC and even threw down a challenge to a certain UFC star no one should ever mess with.

Tread carefully, Marcellus ...

​If Anderson Silva WANTS Roy Jones Jr., he's gonna GET Roy Jones Jr. -- 'cause RJJ tells TMZ he'll accept Spider's challenge to a boxing match ... but the clock's tickin'.

We spoke to the 44-year-old former boxing champ in L.A. this week ... who says he heard Silva loud and clear when Anderson told the New York Post about his dream to fight a "great champion" like Jones.

38-year-old Silva is currently under contract with the UFC ... but suggested that UFC honcho Dana White should strike a deal to make the fight happen.

As for Roy -- once considered the best pound-for-pound fighter on the planet -- he tells TMZ, "I would love it ... Call me and we'll make that happen."

Former UFC fighter Rampage Jackson is BACK -- officially signing a brand new deal with TNA wrestling and rival MMA company Bellator ... and he tells TMZ, the new contract blows his UFC deal out of the water.

Rampage tells TMZ, "When you look at my deal in the UFC, and the scope of what my deal with Bellator and TNA is, this is a dream come true."

He adds, "When other fighters get the chance to see everything I'm able to do with this deal and the benefits it provides, you're going to see a big change in MMA. I guarantee it."

Rampage left the UFC earlier this year on bitter terms ... telling us, the UFC treated him like crap and screwed him over financially. UFC honcho Dana White shot back, implying Rampage was an overpaid wash-up.

Under his new multi-year deal with Spike TV, Rampage will compete in Bellator and also appear on TNA's "Impact Wrestling." He also gets a reality show. So far, no word on how much he's getting paid.

UFC legend Tito Ortiz claims Jenna Jameson is lying through her teeth ... telling TMZ her allegations that he physically attacked her while abusing drugs are complete B.S..

Jenna went on a Twitter rampage yesterday ... claiming Tito beat her up and "almost killed" her ... and "faked" drug tests in order to fight in the UFC.

Jenna tweeted several pictures of prescription drug bottles and syringes -- insinuating they belonged to Tito.

During the Twitter session, Jenna also claimed Tito is unfairly trying to strip her of custody of their 4-year-old twin boys.

Now, Tito is finally responding to Jenna's allegations ... telling us, "The unfortunate allegations being made against me are simply not true."

He adds, "I would never do anything to jeopardize my family. Being a great father and protecting the well-being of my children remains my top priority."

"I thank my family, friends, and fans for their kind words of support at this time. For my children's sake, I appreciate you respecting our privacy."

As we reported, Jenna and Tito's twins are currently under the sole care of their father following a nuclear confrontation over custody last month.

He may have a cracked toe ... a disgusting, bloody, broken toe ... but Jon "Bones" Jones stomached the pain last night and crutched out for some delicious BBQ in NYC.

In case you haven't seen the injury -- don't, it's gross -- but Jones exploded his little piggy during his UFC 159 beatdown of Chael Sonnen this weekend ... and now, he's gotta use crutches to get around.

In fact, Jones felt healthy enough to venture out to Dallas BBQ in Times Square ... and told TMZ he's doing well and feels good.

Vantris Patterson is dead wrong ... the UFC does NOT transform athletes like Phil Davis into violent people outside of the octagon ... this according to UFC honcho Dana White.

White just called in to "TMZ Live" to take on the allegations Davis' baby mama made in her nasty custody battle with the UFC fighter -- that the sport has turned him into a monster.

"Phil Davis ... we've never had problems with this guy EVER," White said ... "He's one of the nicest guys I've ever met."

White says he has hundreds of guys who fight under the UFC banner -- and barely ANY of them have issues with violence after the bell rings.

His explanation -- "When you train, every day all day ... the last thing you wanna do is fight outside the octagon."

10:05 AM PT -- We just spoke to Phil's coach, who told us ... "This is a nasty custody battle, and people are gonna say things that are completely not true ... He's one of the nicest people ... he's a Christian and he's a role model. In fact, he just got back from the Dominican Republic building churches and schools."

And here's a weird one ... Vantris just posted on Facebook that it's all a lie ... saying "Those pictures are not even me ... ." Never mind that she's SAID she filed the same photos ... in court documents.

UFC star Phil Davis has a huge fight Saturday night in New Jersey, but the bigger fight may be May 7 in San Diego, where his baby mama will accuse him of crazy brutality, including violent sex ... and she blames it on martial arts.

According to legal docs -- obtained by TMZ -- Vantris Patterson claims Davis body slammed her on a couch with such force ... when the couch slid into the wall paint came off. She took pictures (below) which she claims show the injuries.

And Patterson says, Davis -- aka Mr. Wonderful -- would often choke her during intercourse, and when she'd plead with him to stop he'd respond, "Shut the f*** up, bitch."

She says Davis has threatened to kill her numerous times if she ever slept with another man.

Now here's the hook -- Patterson claims Davis' alleged propensity for violence has escalated because of his involvement in the UFC. She says, "I am afraid that the numerous fights have negatively impacted his mental stability," and she can't defend herself because of his "increased strength and attacking ability."

Davis makes his own claims ... that Patterson is the violent one who put a pic of a Glock up on Facebook and wrote, "... His day will come." He also says she texted him, "I can't wait until the day you die so I can spit in ur face [painful and slow]."

As for his MMA training, Davis says he's never used his skills outside the Octagon.

When they're in court on May 7, they're both asking for permanent restraining orders and each wants full custody.

Make no mistake about it, Jon Jones doesn't consider Chael Sonnen a "friend" -- even though Chael's been showering him with compliments lately ... in fact, Jones says he can't wait to punch Chael in the face this weekend.

Jones and his team were in NYC yesterday getting ready for the big fight at UFC 159 this Saturday -- when we asked if it would be weird punching a guy who's been so nice lately.

In case you missed it, Chael gushed about Jones to USA Today -- saying he's a "very nice guy" who could've beaten up both Mike Tyson and Muhammad Ali in the same day.

Doesn't seem like Jon was fazed by the flattery ...

As for Chael, he was also in NYC yesterday ... bragging about the size of his cojones. Dude's pretty funny ... check out the clip.
