Nurse!

Akon's ex, Tricia Ana, is nursing a serious injury after brawling at a Hollywood Hills bash, and when the dust settled she was bloodied and missing her bling ... TMZ has learned.

An eyewitness tells TMZ ... the 'Love & Hip Hop' star was partying with a bunch of folks last weekend and, as you can see in the video, not all of 'em were friends. We're told that Tricia, wearing white, got into a heated argument with the woman in a denim jacket ... but it quickly turned into hand-to-hand combat.

Law enforcement sources tell TMZ ... things escalated inside the house before the fight spilled outside with both women exchanging blow after blow.

At one point in the video, you can see Tricia's necklace on the ground ... and moments later it's gone. It appears a guy in white and green pants grabbed it during all the chaos.

We're told the icy jewelry is worth more than $15k!!!

Our sources say a third person got involved when the fight continued outside, and that's when Tricia was sliced across the face. She was taken to a hospital where she got about 20 stitches ... and law enforcement was alerted.

We're told cops are investigating the brawl, but no arrests have been made yet.

Deion Sanders' foot issues were actually MUCH worse than people thought ... 'cause at one point, doctors feared the Hall of Famer could lose his leg.

The shocking detail was revealed in a trailer for the next 6 episodes of Sanders' "Coach Prime" doc with Barstool Sports and SMAC Productions ... showing the Jackson State play-caller in excruciating pain during a hospital visit.

Sanders has previously opened up about the complications he experienced after going under the knife to fix a dislocated toe ... but previously did not disclose much more details.

Now, we know just how serious it was.

"A lot is still to be determined, but he's gonna have a procedure done a little later today," the doctor says in the clip.

"You could lose your leg."

BTW -- Sanders still doesn't know exactly how it happened ... but has been documenting a lot of the process on social media.

The next batch of episodes of Sanders' show will drop starting Feb. 22 ... and will also feature the past football season and an inside look at how JSU landed top recruit Travis Hunter.

"'Coach Prime' is back and I'm ELATED to share this project with you all because WE DON'T HOLD BACK," Sanders says.

"All season, we've been getting questions about what really went down at Jackson State this fall ... We're going to clear up the rumors, set the record straight and always keep it 100% with you."

The extended trailer for "Coach Prime" will drop during Barstool's Super Bowl Live Stream on Sunday.

Don't feel bad, Matt James ... CC Sabathia also hit a guy with an errant tee shot on the course in Arizona on Wednesday -- drilling a Yankees fan in the leg just hours before the 'Bachelor' star hit a photog in the thigh.

CC's unfortunate drive happened on the 18th hole of the Waste Management Phoenix Open Pro-Am ... when a witness tells us the former Yankees superstar pushed his shot so far to the right on the par-4, it struck a man in the leg.

Video, obtained by TMZ Sports, shows the collision was so powerful ... it actually caused the guy to bleed.

Thankfully, we're told the fan ended up being OK -- and, watch the clip, CC was super nice and apologetic about it all.

Sabathia can be heard chatting it up with the man, who actually said he was a big Yankees and CC fan.

Sabathia ended up signing a golf ball as an apology souvenir ... before he headed off to finish out his round.

In case you were wondering, Sabathia is normally a fairly decent golfer -- reportedly with a handicap in the teens.

John Mayer's live show came to a screeching halt Wednesday night after he noticed a fan went unconscious.

The singer was performing at the SiriusXM and Pandora "Small Stage Series" at the Hollywood Palladium ... Heidi Klum and actress Vanessa Hudgens were both front and center and the show was rolling along just great ... that is, until Mayer noticed a fan in the crowd was in clear distress. John abruptly stopped the show.

"Give me a thumbs up if they're alert," he asked the crowd. It was interesting ... the crowd cheered John for showing concern.

The house lights went on and Mayer told the crowd he was stepping off stage as a female was taken out in a wheelchair.

When he walked back on stage, he told the audience: "Anyone in the crowd who was worried, I'm told she waved goodbye, so she's OK. The system works. Thank you very much."

John is the latest performer to stop the show when an audience member had a medical emergency ... a sharp contrast to the Astroworld Festival, where the show when on for 40 minutes after people were dying in the crowd. Billie Eilish stopped her show briefly a few days back when a fan had trouble breathing, and then threw shade on Travis Scott.

Matt James now owes a golf photographer far more than just a bunch of roses ... 'cause the former 'Bachelor' star nailed the dude with an errant tee shot at a Pro-Am event in Arizona on Wednesday, nearly hitting the guy in his family jewels!!!

The hilarious (and terrifying!) scene all went down at the Waste Management Phoenix Open Pro-Am ... when James stepped to the tee box barefoot at the world-famous 16th hole at TPC Scottsdale to try to win some money for charity.

Matt was gunning to be the closest to the pin on the par-3 ... but you can see in the video, he had trouble even getting the ball off the ground.

His first hack was terrible -- he got nothing but grass and dirt -- and then he shanked his second swing so badly, it went 15 yards to the right and drilled a camera guy right in the thigh.

James was super sorry for the miss ... he ran over immediately and gave the guy a hug and offered him the golf ball as an apology souvenir.

The man, meanwhile, said, thankfully, he was OK.

"We came within centimeters of causing some real damage," James said of the shot. "I'm going to try to find him. I'm going to sign this ball for him. And I'm going to take him out to dinner."

Added the photog, "He felt bad. I felt it ... Next year, I'm wearing a cup."

Might be necessary, 'cause James said he intends to come back in 2023 for redemption.

Here's the moment Heather McDonald suddenly collapsed in the middle of her comedy set ... and the video looks, and sounds, painful.

The comedian just addressed the moment she fainted onstage during a sold-out show in Tempe, AZ ... sharing talking about the incident Tuesday on her podcast, "Juicy Scoop." We've received video from the segment showing the scary situation.

As you can see, Heather is just finishing up a joke when she collapses to the floor.

Heather says she's still not sure why it happened ... though she says she didn't eat before her weekend set and only drank half a Red Bull and some water. Heather also shot down rumors someone might have spiked her drink.

TMZ broke the story ... Heather fell hard onstage and hit her head, suffering a skull fracture.

Heather says she got a cat scan and a battery of other tests, all of which she says came back totally normal.

"The Wendy Williams Show" has been a revolving door this season as the host struggles with various ailments, and now TMZ has learned a "'permanent guest host" is about to be named.

Multiple sources with direct knowledge tell TMZ ... Sherri Shepherd will take the reigns of the show beginning in September. Our sources say the deal is almost locked, and everyone involved expects it will be inked in the very near future.

Now, here's the way it will work. The folks who produce the show will be monitoring Wendy's progress between now and September. If Wendy gets better, there's an open door for her to return. If, however, it appears she is unable to return, then they would change the name of the show as early as September ... which will mark the 15th season of the show.

Our sources say the Fox Station Group -- which carries the show on its owned and operated stations ... is on board with the move.

Wendy stepped away from her show back in October after suffering "serious complications" from Graves Disease as well as a thyroid condition ... this all coming after she battled COVID-19.

Wendy's last appearance on the show came in July 2021, when she signed off at the end of season 13, telling fans she'd see them for season 14.

That never happened, but the show has since continued to air with a multitude of guest hosts including Bill Bellamy, Whitney Cummings and Leah Remini.

Dana White shared some graphic photos of Kamaru Usman's open hand surgery on Monday -- and, WARNING, you better be done with breakfast before clicking on the pics!!

Usman had to head under the knife after he jacked up his hand in a sparring sesh just weeks before he beat Colby Covington at UFC 268 in November -- and the procedure was clearly no cakewalk.

You can see in the photos that White shared -- docs had to open up the top of Usman's right hand with some beefy utensils to repair the damage.

The before and after pics are gruesome -- they show docs cutting into the hand to fix it all up.

Despite the gnarly nature of the injury, White expressed optimism for a quick recovery -- saying in the caption that he'd see Usman "soon."

As for Kamaru, he posted a video from the hospital bed Monday ... clearly showing he ain't going to let the operation hold him back too much.

No official word on when the Nigerian Nightmare will return to action ... but his manager, Ali Abdelaziz, told us recently he'd like to see the fighter take on Leon Edwards next.

Comedian Heather McDonald fell hard during a show in Tempe, Arizona, but it was no joke ... it was a medical emergency.

Eyewitnesses tell TMZ ... the former "Chelsea Lately" star was headlining the sold-out show, when she delivered her second joke ... "I'm vaxxed, double vaxxed, boosted ... and flu shot and shingle shot and haven't gotten COVID and Jesus loves me most."

As soon as she delivered the joke, she just collapsed and hit her head on the floor. Everyone thought at first it was all part of the act, but it was not. She was conscious, but clearly, all was not well. An EMT and a nurse happened to be in the audience ... they rushed up on stage to provide first aid.

The 911 call came in as a seizure, but no one really knows yet. An ambulance came and paramedics tended to Heather.

Heather tells TMZ ... she felt somewhat dizzy when she was on stage and then just collapsed. She says it's never happened to her before.

She passed on the ambulance ... she says her sister-in-law -- who was in the audience -- took her to the hospital.

Heather says she got a cat scan as well as other tests, but so far it's unclear what caused her to faint. She says her head really hurts and she's very tired.

Ever the trooper, she says she feels horrible about abruptly ending the show.

Heather tells us she never had COVID and, as she said in her set, she's fully vaxxed and boosted.

We wish her well.

Billie Eilish brought her concert to a full-stop halt over one fan who appeared to be in distress -- and if you're thinking about Astroworld Fest here ... well, so was she.

The singer was performing in Atlanta Saturday, where State Farm Arena seemed to be packed to the gills with fans -- especially down below near where she was performing ... and where one gal apparently started getting crushed in the pit.

Check out this video we got of the moment BE paused everything once she became aware of what was going on ... it seems the lady in question was having trouble breathing, and needed an inhaler.

Luckily, Billie actually had one on hand ... and instructed the stage crew to get it to her ASAP. While the fan was being attended to, Billie settled down the crowd, told them to take a deep breath and step back -- at the same time, noting she wants to take care of her own ... something she's made sure to do in past concerts of hers as well, dating back years.

Then came a shot at what was clearly aimed at Travis Scott, with Billie saying ... "I wait for people to be okay before I keep going." That got huge cheers from the audience.

Of course, she's referencing the fact that Travis' November set continued for several minutes after the event was declared a mass casualty event -- with many suspecting TS was aware of what was going on. He's strongly denied that, claiming ignorance to the severity of things.

What's interesting here is the fact that Billie is replacing Travis at Coachella this year. Although an official announcement has yet to be made, the cat's outta the bag -- he got bumped amid the controversy -- other headliners dropped out too, FWIW -- and BE's one of the new artists who've been tapped in their stead.

Odell Beckham came through with an amazing gesture for a man fighting cancer ... by sending a personal message of encouragement during his challenging time.

TMZ Sports is told ... 43-year-old Dominic Tafuri is a former MMA fighter and current officer with the Essex County Department of Corrections in NJ.

Dominic also worked for Odell's go-to guy for bling, Gabriel the Jeweler ... delivering pieces to some of the biggest athletes around the world -- from Aaron Donald to Prince Boateng to Ederson.

Tafuri recently found out he had Stage 4 lymphoma after undergoing a routine ACL surgery ... and is now battling the disease head-on.

We're told Tafuri is like a brother to Gabriel, so the jeweler hit up OBJ and asked him to improve Dominic's spirits ... and the Rams star delivered!!

"Dominic, what's going on, man? OBJ here, bro," Odell said in the video. "Just wanted to reach out to you, send some love your way."

"Just stay encouraged, man," he added. "Stay prayed up, man. Just know I'm praying for you, and just wanted to send some love, bro. Stay up."

FYI -- there's a GoFundMe set up to help Dominic and his family during this time ... with a goal of raising $100k.

A man has been tracked down and arrested in connection to the SoFi Stadium parking lot fight that left a man hospitalized in a medically induced coma, officials say.

Inglewood mayor James Butts Jr. announced the new development on Thursday ... saying a Montebello man was traced to his home using surveillance footage that started in the SoFi lot.

Butts claims the footage shows 40-year-old Daniel Luna allegedly pushing a man in a Rams jersey from behind. The man who was pushed then retaliated, the mayor says -- shoving Luna and punching him in the face.

Butts says Luna fell to the ground ... and that's where he remained until he was found by a stadium employee.

As we previously reported, officials were criticized for seemingly dragging their feet in sharing the news about the attack ... with some believing it was to prevent a PR nightmare prior to the Super Bowl.

SoFi Stadium released a statement on the beatdown ... saying, "We are aware and saddened by the incident. Our thoughts are with Mr. Luna's friends and family during this difficult time."

"We are working with law enforcement officials in their investigation.''

The 49ers also released a statement ... saying, "What happened to Daniel Luna is reprehensible and we strongly condemn all violence."

"We know local authorities are conducting a full investigation and we're here to support them however we can."

"Our thoughts and prayers go to Mr. Luna, his family, friends, and the medical team providing him care.''

The identity of the person -- and the charges they were booked on -- are not yet clear.

Kevin Smith says there were 2 main factors in his decision to stop consuming animal products ... his near-fatal heart attack, and his daughter's master plan.

We got the director leaving Crossroads Kitchen in L.A. -- one of the most famous vegan joints in town -- and asked him if the vegan lifestyle is the secret to his vastly improved fitness.

Kevin's looking pretty good these days, and he explains how he made some big changes in his life after suffering that massive heart attack back in 2018.

He says after learning he had a full blockage in a major artery -- which caused the widowmaker heart attack -- he sat down with a nutritionist, and finally followed his daughter, Harley, to the vegan side.

Kevin, who initially thought he was having a reaction to spoiled milk when he had the heart attack, is only eating plant-based products these days and he tells us why he'd never followed Harley's lead before.

The way Kevin explains it ... she was pretty Machiavellian about it, but he's grateful she was.

There's new alleged video proof that supports a man's claim he was injured during a Jet Ski stunt gone wrong involving "Jackass" stars Steve-O and Chris Pontius.

TMZ broke the story, Michael Vicens-Segura is suing the veteran stuntmen for an incident he says, left him badly injured, suffering a gash on the side of his head.

In the video, you can see Vicens-Segura in the water between the vessels just before they take off, once the Jet-skis moved, Vicens-Segura was allegedly struck by the cable connecting the two when it snapped.

The aftermath is intense, and Michael is clearly in a lot of pain.

Michael says the whole thing happened in Puerto Rico in 2018 when the two guys and movie producers planned to do some kind of "Jet Ski Tug of War" ... which basically meant two guys would operate the jet ski in opposite directions.

Michael's attorney, John Phillips, now says ... "We provide this video looking for witnesses and people who know about the creation and execution of this stunt. If you have information, please contact us."

Vicens-Segura says he had to get a metal plate in his head and his life has been completely changed by the incident ... he is asking for more than $12 mil in damages.

Scary moment during a WWE NXT UK match Thursday ... Blair Davenport suffered a gnarly leg injury after she jumped off the top rope and landed on the ground awkwardly.

Davenport was competing against fellow wrestling star Meiko Satomura in a Japanese Street Fight for the NXT UK Women's Championship ... when disaster struck.

During the match, Blair climbed to the top of a ring post, jumped, and then slammed her feet onto the back of Meiko, who was outstretched on the apron.

But, when Davenport hit the ground just after that, you can see in video, her ankle and knee crumpled below her body.

Davenport was hurt so badly, she screamed in pain. The ref then immediately ended the match.

"This is really hard to see," one announcer said. "When any competitor gets hurt, regardless of how physical this match was, it's tough to watch."

Satomura -- the reigning champ -- looked concerned the entire time while Davenport received assistance from the medical staff.

Blair posted an update on her Twitter account following the match ... showing a picture of her on crutches and in a walking boot.

"Whoops😬 BRB ✌" she said.

Steve-O and Chris Pontius are responsible for a 'Jackass'-style water stunt that left a man with a busted up head and a ruined life ... at least according to a lawsuit filed by the guy who claims he was injured.

The veteran stuntmen are being taken to court by Michael Vicens-Segura, who says he was approached by them back in 2018 to see if they could use his jet ski for a project they were filming in Puerto Rico.

Vicens-Segura insists the guys wanted to use it for a 'Jackass'-y feat -- where 2 guys are in the water on jet skis, facing opposite directions ... and attached to one another by a bungee cord, to see who would get yanked off first as they sped off.

Essentially, it's a jet ski tug of war ... and Vicens-Segura says the 'Jackass' guys have done something similar in the past -- in their movie, no less. It was called the BMX Tug of War.

Now, per the lawsuit, filed by attorney John Phillips and obtained by TMZ, Vicens-Segura was asked to hold one of the jet skis steady in the water because of the waves that day ... which he says he did. He claims, as Steve-O and Chris hit the gas, Steve's bungee cord snapped off the harness attached to his back ... which he says then flung in his direction and popped him hard on the side of the head, resulting in a massive gash.

Vicens-Segura says he had to be helicoptered to a hospital for emergency surgery, and even needed to be placed in a medically induced coma because he had a fractured skull and brain bleeding, among other things.

After several medical procedures, Vicens-Segura claims he was left in bad shape as he recovered ... and also had some pretty gnarly scars. He claims he's lost his ability to work, to think straight ... and continues to experience pain, suffering and agony because of what happened to him.

Of course, he's blaming Steve-O, Chris and others for the whole thing ... suing them for negligence and moreover the alleged incident. He's asking the court for more than $12 million in damages.
