Nurse!

Forget the 'Hotline' -- Pretty Ricky member, turned 'L&HH' star, Baby Blue allegedly put a guy in line at the ER when a fight broke out while shooting the reality show.

Eyewitnesses tell TMZ ... Baby Blue brawled with a guy named Dante Wednesday in Miami. Dante was helping BB's ex-fiancee, Michelle Carolus, move her stuff out of Blue's house. We're told Michelle -- who's one of the Double Dose Twins -- recently called off their engagement and wanted to bolt ASAP.

Blue wasn't cool with that, and our sources say things got physical and after the fight, Dante was left with a nasty gash. It was so bad, he needed to go to the hospital for stitches.

Cops were called, but law enforcement sources tell us both men were gone by the time they got there.

Sources close to the production tell us VH1 crew members were present to shoot a confessional with BB, but were not rolling when things got violent.

12/5 -- Laila released a statement ... saying she's okay and she's praying for the elderly man who was injured. Laila says the man was walking behind her car when she was backing up. Laila also says her 7-year-old daughter, Sydney, was in the car at the time of the accident.

Laila Ali was involved in a serious accident in Calabasas that left a pedestrian seriously injured ... TMZ has learned.

The accident went down Tuesday afternoon in Calabasas. We're told Laila accidentally hit an elderly man while driving through the parking lot of a shopping center. Paramedics and L.A. County Sheriff's deputies quickly responded to the scene.

Medics treated the victim on the scene, but he was eventually taken by ambulance to a hospital and is in stable condition ... according to our law enforcement sources.

Muhammad Ali's daughter remained at the scene and spoke to Sheriff's deputies once they arrived. The former boxer -- turned host/actress/author -- was not arrested or cited, for now -- and we're told the Sheriff's Department is investigating this as an accident.

We've reached out to Laila's reps for comment, but haven't heard back yet.

Story developing ...

3:46 PM PT -- We spoke to Briana who tells us her body's in a lot of pain but otherwise doing okay. She says she's waiting for the shock to settle and is currently being looked after in the hospital.

Briana Renee's car -- or what's left of it -- looks like she should've severely injured when she slammed into a pickup truck ... but by some miracle, she's okay.

TMZ obtained these pics of the ex "Little Women: LA" star's Audi after she got into a car wreck Friday in Temecula, CA. The front end of her ride, especially on the driver's side, is crushed.

Brianna says she was doing about 35 MPH when a pickup truck unexpectedly turned left in front of her. She says the impact felt like hitting a brick wall. The car looks like she did, too.

Briana says her airbag did not deploy, but still ... she felt like an angel had unfolded a cushion to protect her from slamming into her steering wheel. She was alone in the car.

4:05 PM PT -- Sources tell TMZ, doctors who performed the surgery discovered her throat cancer has returned. Doctors say it's too early to give a prognosis, but it's serious. They're currently evaluating treatment options.

2:01 PM PT -- A source tells us Beth's surgery has just ended, and she's now being taken into recovery. We're told her family will have a better idea of how the procedure went shortly.

Beth Chapman -- wife of Dog the Bounty Hunter -- has been rushed to surgery to remove a life-threatening blockage in her throat ... TMZ has confirmed.

Sources tell us it became difficult for Beth to breathe overnight and she was rushed to Cedars-Senai Medical Center early Tuesday morning ... where doctors discovered a large mass in her throat.

Our sources say Beth was just put under anesthesia within the last 30 minutes and her emergency surgery is about to begin.

We saw Dog and Beth leaving Craig's in West Hollywood Monday night -- both seemed to be in great spirits -- with an interesting take on Tekashi69's bail situation. Clearly, things took a turn for the worse once they got home.

Beth underwent surgery last year to remove a cancerous tumor in her throat, which seemed to work.

After her initial cancer diagnosis, Beth told RadarOnline.com, "I've stared down the devil more than once in my life but I've never faced a real life or death decision. My life has never been easy, and I surely don't expect it to start now. Still, I've never been a victim and I won't let cancer beat me."

The family's attorney, Andrew Brettler, tells us Beth's condition is serious and everyone is hoping for the best outcome.

We're told Dog is by Beth's side at the hospital, and more family is on the way.

UCF quarterback McKenzie Milton won't lose his leg after suffering a devastating knee injury last week ... his family announced Tuesday.

Milton dislocated his right knee after taking a vicious shot in a game against USF last Friday ... and there was some worry that the injury was so gruesome, he might lose his leg.

But, Milton's parents said in a statement that while there is nerve damage and he will later require reconstructive knee surgery ... blood flow has been restored to the leg.

"We want to thank the doctors and nurses at Tampa General Hospital and the University of South Florida and UCF medical staff and athletic trainers for their teamwork and prompt attention to McKenzie’s injuries," Milton's parents wrote.

"His blood flow has been restored to his right leg and his nerve is injured but intact. He is recovering and healing and is receiving the best medical care."

Mark and Teresa Milton added, "McKenzie and our entire family are so touched and grateful for the prayers, support, and well wishes. McKenzie is in good spirits and has a very positive attitude.”

UCF plays next in the American Athletic Conference Championship Game against Memphis on Saturday ... and Milton's family says the QB will be cheering them on.

WWE superstar Kairi Sane -- former NXT women's champ -- says she's debating whether or not to go to the hospital after coming down with a case of hand-foot-and-mouth disease.

Sane tweeted (translated from Japanese) -- "Although high fever went down, mysterious eczema in hands, feet and mouth this time ... Ouch."

"So when you go to the hospital (hand foot/mouth disease) do you?! (Hand, Foot and Mouth Disease as it is in the United States) If infants are examined Infants under 5 years old suffering illness. Why did you get in my body by mistaking a virus? Lol."

According to the Mayo Clinic, HF&M is a "mild, contagious viral infection common in young children" and it's usually characterized by sores in the mouth and a rash on the hands and feet.

Treatment?

"There's no specific treatment for hand-foot-and-mouth disease. Frequent hand-washing and avoiding close contact with people who are infected with hand-foot-and-mouth disease may help reduce your child's risk of infection."

The good news ... Mayo says the symptoms should only last a few days. (Drink lots of water).

Here's what Willis was talkin' 'bout ... Todd Bridges getting knocked the hell out -- on camera no less -- while trying to be a nice guy, backing up a friend in need.

The "Diff'rent Strokes" star recently helped his wheelchair-bound neighbor evict a woman living at the guy's house in the San Fernando Valley. We're told Todd's neighbor had asked him for help in the past, and Todd obliged this time too.

Well, things escalated quickly. Todd and the woman's boyfriend got into a verbal altercation, and next thing ya know ... Todd got sucker punched and laid out. It's pretty crazy ... in this surveillance footage, obtained by TMZ, you can see Todd was totally dazed from the hit.

We're told the guy fled the scene, but no police report was filed. As for Todd ... he tells us in a statement ... "No one likes to be sucker punched, but I am glad that I was there to help my neighbor, who was faced with a potentially dangerous situation."

Todd added, "Much rather it was me, and not my neighbor."

Laura Avila, the Dallas realtor who ended up in a coma after a botched nose job procedure in Mexico, has died ... TMZ has learned.

Laura's death comes days after her family made the difficult decision to move her to hospice care, following deliberations with her medical team.

As we reported ... Laura slipped into a coma after surgeons in Ciudad Juarez botched her nose job by incorrectly administering anesthesia. She had gone south of the border for the procedure to save some money ... and was stuck there for 8 days before her family was able to transfer her back to Texas.

Laura's attorney, Larry Friedman, tells us ... "She had the best of life in front of her until this tragic, unfortunate and senseless death. So that her death is not in vain, people should think of Laura before they look for cross border discount surgery. They should do their homework and investigate the experience, training and track record of anyone BEFORE they sign up."

He adds ... "Always LOOK before you leap!"

Joe Theismann says he was so shook after watching Alex Smith's brutal leg injury on Sunday, he couldn't sleep that night ... telling TMZ Sports it's brought back some painful memories.

Joe was at FedExField on Sunday when Smith took a hit from J.J. Watt that snapped his fibula and tibia -- a compound fracture where the bone broke through the skin.

Of course, Theismann was on the receiving end of a similar hit back in 1985 when Lawrence Taylor brutalized him on "Monday Night Football" ... causing the same injury.

"It was so surreal yesterday in the stadium," Theismann told the guys on the TMZ Sports TV show ... "to have what happened to Alex on the day it happened to me 33 years ago."

Joe says the similarities between the two are eerie.

"It was I think 166th game for Alex. Mine was 167. Basically, the same place on the field. Heck, I have a nephew named Alex Smith who's 33-years-old ... the whole thing is crazy."

Theismann says for the first time in his life, he couldn't really sleep after watching the injury in person -- saying, " I didn't really think this thing had bothered me as much as it did, and I think it probably got to me a little bit more."

Joe says he considers Smith a friend and plans on reaching out to the QB after giving him some space to deal with the injury.

The big message for Smith -- Theismann says there's light at the end of the tunnel ... so don't give up hope.

Bob Barker was rushed to the hospital for the second time in 2 months, but it sounds like it's another case of a bad back ... TMZ has learned.

The former "Price is Right" host was taken to Cedars-Sinai hospital by ambulance Sunday afternoon after suffering severe back pain at his Hollywood Hills home.

His manager tells us Bob is doing better now that he's under a doctor's care, and that this most recent hospitalization comes as a result of severe back pain related to his 2017 fall. He's fallen at least one other time before -- a 2015 spill that split his head open.

Sophia Floersch -- a German Formula 3 driver -- survived a terrifying crash during a race in China that easily could've killed her ... but left her with a fractured spine instead.

The 17-year-old was racing in the Macau Grand Prix Sunday when she reportedly collided with another driver, lost control on a sharp right turn, flew right through some crash barriers and landed in a photographer area. The accident is as bad as it sounds ... listen to the crowd scream in shock as her car gets airborne and smacks against a fence.

Incredibly, Sophia's racing team said she was conscious and stable, but had suffered a spinal fracture. They also listed her as "not fit to race," but did not say for how long. At least 3 others were also injured in the crash, including 2 photogs and the other driver.

Sophia later tweeted that she was "fine," and was going into surgery Monday morning. She added that she'd be providing updates soon.

David Arquette vows his incredibly bloody deathmatch was his last, but he's never going to take his foot off the gas.

We got David Saturday in L.A. ... a day after his brutal Game Changer Wrestling fight against Nick FN Gage. David kinda looked worse for wear, after Nick smashed a light tube against his face. Check out the huge scab on the side of his neck.

So, David says -- we're not sure if he's serious -- the only rematch he'll have with Nick will be in a UFC Octagon.

As for David just sitting back and becoming a spectator in life ... well, he scoffed at the notion. He's always been a fighter and never a couch potato.

Amy Schumer is back on her feet after suffering a pregnancy complication.

Amy was out and about in New York City Saturday ... this after she posted a pic of her in a hospital bed saying the baby was fine but she was suffering from hyperemesis -- AKA extreme morning sickness.

Amy canceled her Dallas show Friday night, but she was back in business Saturday, performing her comedy show in Newark, New Jersey, at the Performing Arts Center.

She's scheduled to perform Sunday in Pittsburgh.

Laura Avila, the Dallas realtor who ended up in a coma after a botched nose job procedure in Mexico, has been moved to hospice care ... TMZ has learned.

Laura's attorney, Larry Friedman, tells TMZ ... Laura's family made the difficult decision Saturday to move her into hospice, and the family believes her life is now in God's hands.

We're told the family decided hospice was Laura's best option after deep deliberations with her medical team.

As we reported ... Laura slipped into a coma after surgeons in Ciudad Juarez botched her nose job by incorrectly administering anesthesia.

We've just obtained shocking new video of Lil Pump moments after tear gas was dispersed at his concert ... and it's clear the rapper felt the full brunt of the attack.

You see a shirtless Pump rapping and hyping up the crowd as he stands on the edge of the stage, and that's when then the concert comes to a screeching halt as Lil Pump apparently starts smelling the gas.

Lil Pump has a puzzled look on his face as he slowly realizes something's not right, he lowers the mic and starts retreating off stage.

Backstage, Pump is nearly unconscious as he's getting treated by medics. Fortunately, he's able to recover and he climbs on top of his tour bus and finishes the show.

The crazy scene went down Friday night at Rock City in Nottingham, United Kingdom after someone tossed tear gas into the crowd.

The crowd may have gotten the worst of it because fans were sent scrambling as gas fills the auditorium. The building was evacuated and cops tell us at least two people were treated for minor injuries.

It's still unclear who launched the attack, but law enforcement sources tell us the incident was not terrorism.

David Arquette was bloody, mangled and nearly tortured Friday night in a wrestling match ... and there was NOTHING FAKE about it.

David was in a 'deathmatch' -- that's the name and not really an understatement -- at a Game Changer Wrestling event that went down at The Hi Hat.

The actor-turned-wrestler was up against Nick FN Gage and it was just brutal. Gage broke a light tube over Arquette's head. You see David grab his neck as blood pours from the area. Shockingly, the fight continues.

Toward the end, it looks like David gives up, climbing out of the ring, but then the 47-year-old hops back in as he bleeds profusely. Gage stomps on him, but David fires back by smacking Gage with a chair. It didn't take long ... David gets pinned.

After the match, David told his fans he needed a few stitches and he was fine.
