If Ricky Stenhouse Jr. and Kyle Busch wanna take their beef from garages and pit roads to an actual squared circle ... TMZ Sports has learned Celebrity Boxing is more than willing to put on the bout for them.

Damon Feldman -- the honcho of the fight org. -- said in a video message Monday he's ready to put the wheels in motion on a boxing match between the NASCAR stars ... as soon as they give him the green light.

"Come on, NASCAR," Feldman said, "let's make this the biggest deal in the country!"

11:02 AM PT -- Sources with direct knowledge tell TMZ ... 50 Cent, Dr. Dre and Jimmy Iovine were among the guests at Hailie Jade Scott's nuptials -- so it was more star-studded than anyone initially knew. Keeping it in the Aftermath family!

Eminem cleaned out his closet and put on a tux this weekend -- 'cause his daughter got hitched ... and the father of the bride was front and center to see his little girl through it all.

The rapper's second oldest kid, Hailie Jade Scott, married her fiancé Evan McClintock Saturday in Battle Creek, MI -- at a ceremony we're told was modestly sized with close friends and family.

Julia Fox is vocalizing her support for Cassie in the wake of the Diddy assault video ... sounding deeply disturbed while discussing the triggering footage.

We caught up with the actress on the streets of NYC Monday, where she weighed in on the Diddy-Cassie saga ... which had a major update last week. As we reported ... hotel security footage from 2016 surfaced on CNN Friday, showing the rap mogul beating on his ex.

Diddy has since apologized for the incident, calling it one of the darkest times of his life ... but JF isn't showing him so much grace -- instead slamming the whole thing as "disgusting."

Baby Bash wasn't about to let his fans starve after he rocked the stage and the "Suga Suga" rapper dropped mucho dinero to feed the flock!!!

Bash performed at Santa Clarita's Tequila and Taco Festival on Saturday around 10 p.m. but ironically, he didn't get a chance to eat any for himself -- the stands shut down by the time he was finished.

He rallied the lingering fans backstage and invited them to storm the street with him, and eat any tacos they could find -- they stumbled onto a local vendor who was being moved off the block, but Bash saved the day with big bucks.

There are lots of reasons to drag Diddy over his video apology -- the public outrage is still fresh over what he did to Cassie -- but when it comes to him not saying her name in the mea culpa ... there's a legal reason he couldn't.

As you know, Diddy and Cassie reached a settlement one day after she filed her sexual assault lawsuit against him in November -- and sources familiar with the agreement tell TMZ ... it includes a very strict NDA, which prevents both of them from speaking about each other in public.

You'll notice -- since the release of the 2016 beating video -- you have not seen or heard Cassie trashing Diddy, as you'd expect.

Rich The Kid just took a plea deal in his Miami Beach trespass and resisting arrest case from December that impeded a bomb threat investigation ... TMZ Hip Hop has learned.

We're told the "Carnival" rapper agreed to plead no contest to the resisting arrest and trespassing charges on Monday in exchange for avoiding jail time with a sentence of time served for the 1 day he already spent in Miami-Dade County jail at the time of the arrest ... and a $1,000 fine.

Rich’s lawyers Bradford Cohen and Saam Zangeneh tell TMZ Hip Hop … "We believed that if we proceeded to go to trial we would have been successful."

Britney Spears is in increasing danger of hurting herself or others, or even worse ... so say numerous people in and around her life, and they are scared for her and believe the only path for long-term survival is another conservatorship.

Multiple sources with direct knowledge tell TMZ, Britney's mental health has been in a tailspin since the conservatorship ended. They say she often is not taking the meds that stabilize her, and she is drinking and using various drugs which is especially dangerous, because she has substance abuse problems that sent her to rehab multiple times.

We're told Britney has radical mood swings and often goes into rages that end in physical violence. There are times we're told it's impossible to communicate with her because she can't engage in rational conversation.

Zak Bagans is turning up the heat with some paranormal passion, 'cause he's been busy conjuring up the spirit of a haunted brothel's former madam, and he says he captured proof she's still plenty saucy!

TMZ's got a sneak peek of the upcoming "Ghost Adventures" episode where Zak goes to an Ogden, UT brothel and tries to lure its long-deceased madam, named Rose, with a little cold, hard cash -- but what happens next is a historic, and hilarious, first for the series.

As you can see, Zak gets comfy on the bed waiting for Rose's spirit ... but when she quite literally ghosts him, he calls in his fellow paranormal investigator Aaron Goodwin to take his place.

The WNBA is boomin' right now ... and it's all thanks to Caitlin Clark and the league's new crop of rookies, at least that's according to Tina Charles, who's crediting the youngsters for injecting a whole new life into the game.

The Atlanta Dream star didn't mince words when TMZ Sports caught up with her at LAX this week ... saying straight up the WNBA's "new generation" is responsible for all of the new buzz that's now surrounding the league.

"The energy that we're getting, the reception, the eyes that we're getting on us -- this is amazing," the center said.

Austin Rogers isn't turning his nose up at the pop culture "Jeopardy!" spin-off ... saying trivia buffs like him are cool with the traditional game -- but, there's a new breed of fans out there.

We caught up with the "Jeopardy!" champ this week at his bar Gaf West in NYC ... and we had to ask him about his thoughts on the new entertainment-focused game coming to Amazon Prime.

Rogers says he loves the democratization of his fav trivia game ... mentioning people have different interests and knowledge bases -- and, that's something to celebrate, not denigrate.

The new documentary about Ashley Madison's infamous cyberattack isn't warning people away from the service ... according to one exec, it's actually boosting membership, including famous folks!

We talked with Paul Keable -- the Chief Strategy Officer for Ashley Madison -- and he tells us memberships are up in recent days thanks to "Ashley Madison: Sex, Lies, and Scandal" going #1 on Netflix. Paul figures it's partly 'cause people forgot the site exists until they saw the doc.

Paul says celebs do still use the site despite the 2015 hack that leaked many prominent people's names as allegedly having accounts. He thinks this is because they're dealing with the same issues as normies, feeling trapped in monogamy and it gives them a chance to explore in a safe space.

If ya don't know, Ashley Madison launched as a dating site for married people, and still promotes itself with the tagline ... "Life is Short. Have an affair."

If Paige Spiranac wants to prove to the world once and for all she does, indeed, have nipples ... TMZ Sports has learned one adult website is willing to shell out a small fortune for her to do it on camera.

Reps for Camsoda tell us ... they officially extended the offer to the Sports Illustrated model and golf influencer on Friday, after learning there were actually people on the internet who wondered if her now-famous boobs have nipples attached to them.

Paige, of course, debunked the theory with her words in an Instagram post earlier this week ... but Camsoda officials say they can fork over $250,000 for her to prove it for good on video.

Forget the first inning, Jimmy Rollins says Shohei Ohtani should focus on the ninth innings when he fully recovers from Tommy John surgery ... telling TMZ Sports he believes the Dodgers star's future on the mound is as a closer.

The 29-year-old, of course, has been a starter and a designated hitter throughout the majority of his historic, two-way career ... but after having his second major elbow procedure this past offseason, Rollins told us he thinks Ohtani should have a very limited pitching future going forward.

Specifically, the former Philadelphia Phillies shortstop says he would like to see Ohtani bat at the dish and then be used out of the bullpen once healthy ... in an effort to preserve his golden arm.

Francis Ford Coppola either has another masterpiece, or a dud in his new "Megalopolis" movie -- and amid comparisons to "The Room," one of its OG stars is betting on Coppola.

Word outta Cannes is that FFC's self-financed passion project is such a mess that it compares to the 2003 cult classic film by Tommy Wiseau -- which has been labeled so-bad-it's-good.

Greg Sestero played the dude who was Tommy's best friend in the flick -- he was on the receiving end of Tommy's infamous "Oh, hi Mark" line -- and he told us if Francis' movie is being compared to their flick, he's most likely got magic on his hands.
