The good news for 2 couples on the upcoming season of 'Marriage Boot Camp' is they've already proved they have each other's backs -- unfortunately they proved it during a knockdown, drag-out fight.

Sources close to production tell TMZ ... they had to stop shooting this week after a huge fight erupted over ex-'Love & Hip Hop' star Hazel-E's Instagram. We're told the issue was a racially-charged post from way back in 2017.

We're told Shanda Denyce, wife of Day26 singer Willie Taylor, confronted Hazel about her comments insulting darker-skinned black women ... and then all hell broke loose.

Our sources say Shanda and Hazel-E started brawling first, tearing down a set of drapes in the 'Boot Camp' house in the process.

Meanwhile ... we're told Hazel-E's BF, model Devon B, and Taylor started rumbling and got completely out of control. It took several security guards and crew members to break them up ... but not before a marble table was cracked and several chairs were destroyed.

Once the dust settled, our sources say producers put the cast on lockdown -- and then had an emergency producers-only meeting. We're told they've resumed shooting, and all the couples are still there.

Pennywise the Clown is back in town -- meaning another freaky 'IT' pop-up has returned to L.A. -- which TMZ got to check out ... and now, with our help, you can float too!!!

The IT Experience: Chapter Two rolled into Tinseltown last Thursday -- and over the weekend, our very own photog Charlie Cotton and his lovely wife, Erin, dove head first into the carnival-like attraction on the corner of Hollywood Blvd. and Vine Street.

It all ended in a nightmarish walk through Derry's own circus funhouse, but before that ... there was lots to do!!! The pop-up's got some cool stuff -- a Pennywise-themed Ferris wheel and classic carnival games served as a great warm-up before the final destination.

Check out this year's 'IT Experience' -- a bit more elaborate than 2017's, seeing how it'll take you roughly half an hour get through this thing. But, you also get more of it now.

Instead of sticking to the Neibolt house, you'll actually visit more in-film locations this time -- Mrs. Kersh's apartment, the sewers, and the Chinese restaurant the Losers reunite in.

Long story short, it's a ton of fun -- and if you got a bit more spine than Charlie here ... you should be all good to go. Good luck though, walk-up line times are running up to 6-hours long so far ... and the pop-up sold out on reservation spots within 31 minutes of going up.

We can help you out though!!! Here's the deal -- TMZ is offering a jump-the-line pass if you book a tour with us through September 8. It's like a shortcut ... to HELL (kidding).

Young Thug's got a fascinating obsession with slithery creatures ... especially if they're shiny, 2-headed and cost more than your average house in the heartland.

The 'Slime' rapper is flossin' some new bling worth a whopping $250,000!!! It's a 2-headed snake chain made of 18k rose gold and features over 90cts of diamonds. The whole piece weighs more than 2 pounds!!!

Thugger better hit the weights.

Celebrity jeweler Eliantte is the artist who created the masterpiece and the detail is pretty incredible. It's got lifelike scales and both heads look ready to strike any haters.

We're told YT had the chain delivered to him last week while he celebrated 2 huge milestones ... his 28th birthday and the release of his new album, "So Much Fun."

BTW ... Thug's snake fascination goes back a minute.

In 2017, the rapper used a snake crawling out of a skull for his and Future's "Super Slimey" mixtape cover art. The following year, he sent live snakes in glass tanks to media outlets as a promotion for his "Slime Language" record -- and don't forget he has a snake eating a live mouse in the opening scene of his "Scoliosis" music vid.

Tyson Fury says he'd only need ONE hand to beat Andy Ruiz's ass ... and he tells TMZ Sports he'd even let the fans pick which arm he would use!!!

"I only need one hand for him," Fury said. "One hand."

The boxing superstar's fight schedule is pretty booked up this year ... he's got a bout with Otto Wallin on Sept. 14 and a rematch with Deontay Wilder set for Feb. 22, 2020.

But, Tyson tells us he'd be down for a fight with heavyweight champ Ruiz after that ... saying, "I can never say no to anything."

But, Fury says the fight probably wouldn't be a good one ... telling us he'd wreck Ruiz!!!

By the way, Fury didn't use up all his trash talk on Andy ... he also guaranteed a knockout in his fight with Wilder, saying, "I don't believe Deontay Wilder is going to put the Gypsy King to rest."

Canadian actress Melody Anderson is best known for her role as the travel agent babe who turned into the galactic warrior Dale Arden in the cult 1980 film adaptation of the comic "Flash Gordon."

Melody Anderson is cast alongside other action actors including Brian Blessed as the high-flying leader of the Hawkmen, Prince Vultan, Max von Sydow as the destructive Emperor Ming The Merciless from the planet Mongo and, of course, Sam J. Jones as the quarterback-turned-savior of the universe, Flash Gordon.

Fun Fact: The rock band Queen is credited with the awesome soundtrack throughout the spacey movie.

A source who spoke with Shawn this afternoon says she was blindsided by the divorce ... she found out by getting a call from TMZ.  As for Larry's allegations, the source says the last time Larry was in the hospital, doctors said he might only have 3 days to live.  The source says their estate planning lawyer had told them they needed to update their docs -- something they had mutually agreed to do --  and that's what Shawn presented to Larry recently when he was ill. She strongly denies doing anything that would compromise the inheritance of their 2 sons.  We're told Shawn is "devastated" ... the news comes 2 weeks before their 22nd wedding anniversary.

Larry King is moving on ... once again -- he's divorcing his 7th wife, Shawn Southwick King.

Larry filed divorce docs Tuesday in L.A. Superior Court ... pulling the plug on his 22-year marriage to Shawn. The couple does not have any minor children -- their 2 sons, Cannon and Chance ... are 19 and 20 years old, respectively.

They've been down this road at least once before. In 2010, the former CNN host filed for divorce, and it was actually a race to the courthouse -- Shawn tried to file first, but Larry's legal team was faster on the draw. Didn't matter in the end ... he and Shawn eventually reconciled.

They dealt with more marital turmoil in 2016, when they publicly addressed cheating rumors.

The breakup comes on the heels of Larry's medical crisis in April, where he suffered what doctors described to Shawn as a heart attack.

This will be 85-year-old Larry's 8th divorce ... assuming he goes through with it this time. He married one of his wives, Alene Akins, twice ... that was way back in the 1960s.

Lord, he was born a ramblin' man ...

Offset got pulled over by a cop who had trouble spelling his name, and it was all downhill from there ... except for a very small bone thrown his way at the end.

The traffic stop went down in late March in Sandy Springs, GA outside Atlanta, and according to the cop's body cam footage -- obtained by TMZ -- the rapper very much sounds like a guy who knows he's about to rack up a few tickets.

Things start off on the wrong foot when Offset asks the cop to turn his flashlight off and gets a stern "no" ... and Offset responds in kind when he's asked for his name.

It gets a bit more contentious when Offset asks why he got pulled over and isn't satisfied with the answer. Both parties then make it known they're recording each other -- pretty standard 2019 stuff.

When the cop finally reveals he's writing Offset THREE citations, Cardi B's hubby accuses him of being mad he's in a nice car ... and suggests the officers kids would be disappointed in him.

Offset also vows to beat the tickets in court, but turns out he wasn't up for the challenge. According to legal docs ... he paid the $470 in fines for speeding and failure to maintain his lane, along with $100 for missing a hearing in the case.

The good news -- Offset's citation for not having a license was dismissed, and of course ... he only got a warning from the cop to avoid a 4th ticket.

David Oyelowo has no issue with a black, British actress playing an iconic African-American like Harriet Tubman -- despite lacking roots to American slavery -- because acting is acting.

Yes, you could say the British actor was just defending the home team, but the discussion about Cynthia Erivo's casting as Tubman has some personal relevance for David. Remember, he played MLK in the Oscar-winning film, "Selma" -- so he tackled the Tubman issue with Van Lathan on 'The Red Pill Podcast.'

David said he doesn't understand the controversy, and in the most gracious way possible (it's that British accent) added ... an actor's background shouldn't matter, if he or she gets the job done.

The debate around the Tubman movie is that critics think it's an insult a slap in the face to not have an African-American woman in a role that has so much cultural significance.

David did raise an interesting counterpoint -- about Americans playing Brits -- and also white British actors playing American roles. Daniel Day-Lewis as Abraham Lincoln, or Christian Bale as Dick Cheney. David wondered where was the outrage when those movies were cast??

He suggests there's a "fight for the scraps" mentality in the black community that divides fellow actors instead of bringing them together. Watch the clip ... thought provoking for sure.

Conor McGregor just posted a message to Nate Diaz -- setting the groundwork for a 3RD FIGHT ... and telling Nate, "I'll be prepared."

The Irish superstar noted that Tuesday marks the 3-year anniversary of McGregor vs. Diaz II -- a fight Conor won by split decision at UFC 202 in 2016.

"3 years to the day myself and this Mexican animal went to war," Conor said.

Then he dropped this bomb -- "I’ll be prepared for it when we go again. If we go again."

"If not, respect always. A war for the ages. No bitch talk. Just real sh*t."

Conor also congratulated Diaz on his dominant victory over Anthony Pettis at UFC 241 over the weekend ... saying, "It was motivating to see it for my own comeback."

"I don’t blame you not mentioning me for the trilogy bout post fight, you know what I’m like when I get going. Vicious."

Conor hasn't fought since his loss to Khabib Nurmagomedov at UFC 229 in October -- and while Dana White has told us he expects to see Conor back in the Octagon in 2019, he hasn't specified an opponent.

Clearly, Conor has his eyes on Nate ... but Diaz called out Jorge Masvidal instead.

Mary Lynn Rajskub -- the actress best known for playing Chloe O'Brian on the hit show "24" -- is divorcing her husband of 10 years ... TMZ has learned.

Mary filed legal docs to end her marriage with Matthew Rolph in L.A. on Tuesday. The couple began dating more than a decade ago and had a son, Valentine Anthony, in 2008.

They wed the next year in August 2009.

Along with playing Kiefer Sutherland's trusted sidekick for 8 seasons, she's also had major roles in movies like "Little Miss Sunshine" and "Safety Not Guaranteed" ... and hilariously plays the character Gail the Snail on "It's Always Sunny in Philadelphia."

Rolph is a personal trainer-turned-actor with a few minor roles to his name.

Kanye West's dome-like housing prototypes have drawn the ire of his neighbors for a while, and they just called the cops on him.

Some of Ye's Calabasas neighbors tell TMZ ... there's been a crazy amount of construction work going on at the site. They say construction crews were working for more than 12 hours Saturday -- the city allows construction from 8 AM - 5 PM -- and Sunday as well. The city does not allow Sunday construction.

We're told at least one neighbor called the cops Sunday complaining of noise, and L.A. County Sheriff's deputies responded at 7:30 PM and found a construction crew hard at work on one of the domes.

We're told the deputies told the crew to stop ... and they did.

Kanye's neighbors have been complaining for a while about the prototypes, which he constructed as models for his vision of an egalitarian community.

Turns out Kanye's crew didn't get permits and he was cited for violating the building code. He was given the option to either get the proper permits or tear the 4 structures down by Sept. 15. He's chosen the latter ... thus the continued noise.

It's unclear if Kanye's going back to the drawing board or jettisoning the project.

The guy who appeared, ON VIDEO, to swipe Frances McDormand's Oscar for Best Actress at the 2017 Academy Awards is walking away scot-free ... TMZ has learned.

Law enforcement sources tell us 47-year-old Terry Bryant will not be prosecuted. As for why ... well, Bryant should send a big fat thank you to Frances.

We're told she was not willing to cooperate with investigators, so a judge dismissed the whole matter. Law enforcement sources tell us Frances wasn't down to work with cops from the beginning because she was embarrassed by the whole caper. She had merely left her Oscar to be engraved at the end of the ceremony, and then it turned into a whole media circus.

We're told Frances didn't even want to file a police report, but because the Academy of Motion Pictures actually owns the statuette ... it was listed as the victim, not Frances. However, she was the witness and prosecutors needed her testimony.

The D.A. tells us, "The District Attorney’s Office today told the court that we are unable to proceed at this time. The defense moved to dismiss the case, and Los Angeles County Superior Court Judge Sam Ohta dismissed it."

You'll recall ... Frances' golden statue went missing after the broadcast when she was backstage talking to the media. Bryant was seen parading around with an Oscar that was later identified as McDormand's ... and was eventually arrested.

McDormand won the statuette for her portrayal in 'Three Billboards,' and in her epic speech ... she called on more diversity in the industry, from top to bottom.

Shawn Mendes and Camila Cabello have taken their PDA world tour on the road ... which begs the question -- do these two ever come up for air?!?

The "Senorita" singers headed North to Montreal for more QT. When they weren't holding hands on a nighttime stroll, they were gettin' it at a small cafe.

It's been nonstop spit swapping ... sucking face in SFO, cuddling in WeHo and taking it East to South Beach.

So, will summer love blossom in the fall, or fade into the sunset? The doubters say this is all a PR move to hype their song, "Senorita," but it's looking more and more like this is the real deal.

BTW ... "Senorita" is killing it on the charts ... it's number 2 on Billboard Top 100 ... it even beat out Lil Nas X.

Ronda Rousey is so tough, she BROKE HER FINGER on the set of the "9-1-1" TV show -- BUT NEVER BROKE CHARACTER!!!

Ronda -- who plays an L.A. Fire Dept. badass on the show -- was shooting a scene in Mexico last week in which she was supposed to slam a door during a dramatic action moment.

But, as one source put it ... "She was a little over-exuberant and slammed the door on her finger."

We're told Ronda didn't wince, didn't complain, didn't mess up the scene ... instead, she continued to stay in character and finished the scene.

Only after the director yelled "cut," we're told, Ronda FINALLY acknowledged the injury -- saying, "Ow. You're not gonna like this!"

Ronda went to a doctor who diagnosed her with a broken finger -- which is NOTHING for the former UFC superstar.

She got a splint for her hand and went right back to work the next day, our sources tell us.

Hollywood ... it ain't for the weak.
