Nurse!

Teri Garr -- the comedic actress known for her legendary roles in "Young Frankenstein," "Close Encounters of the Third Kind" and "Tootsie" -- is in the hospital following a medical emergency ... TMZ has learned.

Sources close to Teri tell us ... an ambulance was called to her San Fernando Valley home around 10:30 AM Monday, and she was transported to a local medical center.

We're told she may have suffered a stroke, but we have not been able to confirm that at this time.

Garr has a history of serious health issues. She was diagnosed with multiple sclerosis in 1999 after years of dealing with symptoms of the disease and suffered a brain aneurysm in December 2006 that left her in a coma for weeks.

Teri made a recovery though and was able to return to acting until she retired in 2011.

Garr has over 140 film and television credits over the span of her career as well as one Academy Award nomination for Best Supporting Actress for "Tootsie" in 1982. Garr also trained extensively in ballet.

Zac Efron has broken his silence about a rumored illness that apparently almost had him on his death bed -- and he says it's true, but that he's all better now.

The actor posted the message Sunday, writing ... "Very thankful to everyone who has reached out. I did get sick in Papua New Guinea but I bounced back quick and finished an amazing 3 weeks in P.N.G." He continued, "I’m home for the holidays with my friends and family. Thanks for all the love and concern, see you in 2020!"

The update comes amid reports he'd recently come down with typhoid or another bacteria-related sickness while filming his new Quibi show overseas, which required him to be airlifted to an airport in Australia, and then transported to a hospital from there.

According to local outlets, he was released and cleared to travel back to the U.S. on Christmas Eve. On Saturday, he surfaced in L.A. looking relatively healthy with a shopping bag in hand. It's crazy ... typhoid can be fatal if not treated correctly. Definitely scary.

"Bachelor in Paradise" star Dean Michael Unglert got his Christmas miracle ... he wasn't more seriously injured during a Swiss Alps ski accident.

Talk about a glass half full ... Dean suffered a dislocated hip and fractured femur and he had 4 screws and a plate implanted in his leg.

Dean said afterward, "All my life I’ve dreamt about skiing the Swiss Alps. how could you not? they’re huge and beautiful and have some of the best snow in the world. today, however, was not my day. i was sending just a liiiiitle too hard and took a nasty spill which ultimately put me here. and since this is probably going to be the only pic i get in switzerland."

He says he was laying on the mountain injured for an hour before he was able to flag someone down for help. But, once rescuers spotted him, he was airborne and in surgery in less than an hour.

Here's UFC heavyweight Alistair Overeem showing off his new surgically-repaired lip ... after his face was blasted open in a TKO loss to Jairzinho Rozenstruik.

Overeem's face was a bloody mess after the UFC on ESPN 7 event on Dec. 7th ... when Rozenstruik hit Alistair with a crushing right hook in the 5th round that ended the fight with only 4 seconds left.

Overeem was hospitalized after the fight and underwent a surgical procedure to stitch him up ... and ESPN's cameras captured the 39-year-old as he was healing up.

"It was a nice fight," Overeem said ... "It was a good scrap."

"I was winning all rounds, just doing my thing. Too fast of a stoppage if you ask me. I was not out. I was knocked down, getting right back up."

Overeem is the #8 ranked heavyweight in the UFC at the moment -- and seems eager to get back in the Octagon and fight again ... just as soon as he gets cleared.

Tough dude.

Terrelle Pryor is showing off more of the aftermath of his stabbing incident with his girlfriend ... and the NFLer needed 30 staples to close his massive stab wound.

Pryor has been on the recovery since the Nov. 30 altercation with Shalaya Briston at their Pittsburgh-area apartment. Officials believe Briston stabbed Pryor during a physical struggle that spilled into their kitchen.

Pryor was so badly wounded, he bled all over the apartment and all over the parking garage before eventually undergoing emergency surgery in the hospital.

Pryor says he almost died twice in the wake of the stabbing but miraculously pulled through. He was hospitalized in the ICU for several days before being discharged.

The good news -- he's been up and walking and getting better each day ... and the wound doesn't look that bad either (props to the surgeons).

As for Briston ... she's facing 2 felony criminal charges -- aggravated assault and attempted homicide -- and serious prison times if convicted. She was granted release on house arrest earlier this week.

The Ontario Hockey League goalie who nearly bled out on the ice after being severely cut by a skate was just released from the hospital, his team announced Tuesday.

17-year-old Tucker Tynan was in bad shape last Thursday night ... when his leg was slashed after an opponent crashed into him in the Niagara IceDogs' game against the London Knights.

The collision crumpled Tucker to the ice ... and emergency personnel quickly rushed him into surgery after they noticed blood profusely pouring out of his leg.

The good news? Tucker pulled through just fine ... and his IceDogs squad just announced he's left the hospital and is headed home for some R&R.

"Tucker Tynan has been discharged from hospital in St. Catharines," team officials said. "He is en route home to Chicago for some rest and recovery."

For his part, Tynan sent a message from the hospital bed over the weekend saying he was grateful for all the support during the scary time.

"Just wanted to say thanks to everyone for the kind words, truly they mean more than anyone can ever know," Tucker said.

"An unfortunate situation, looking forward to recovering and coming back even stronger and healthier than before."

Cynthia Bailey has a message for all the couples out there this flu season ... she says there's nothing wrong with snuggling up with your sick partner!!!

We got the 'Real Housewives of Atlanta' star at LAX Monday and asked how she's holding up during her bout with the flu ... and Cynthia says her symptoms won't stop her from planting a huge kiss on her fiance, Fox Sports host Mike Hill, who she was on her way to see.

Cynthia is totally open to debating whether couples should sleep in the same bed if someone is under the weather ... but she says there's only one right answer, and married folks better uphold their vows!

Lucky for Mike, Cynthia thinks she's no longer contagious ... but it sounds like she's ready to take care of the sportscaster if she gets him sick.

THIS IS INSANE!!!

The heavyweight boxing champ of South Africa was injured when the ring ropes SNAPPED during his warm-up and he fell out of the ring ... and the whole thing was caught on video.

Ruann Visser (18-2) -- 6'10", 287 lbs. -- was testing out the ropes before his main event title fight in Cape Town on Monday against undefeated Tian Fick (8-0) ... when something went horribly wrong.

The top rope appeared to snap and 29-year-old Visser went flying backward out of the ring, crashing headfirst on the hard ground.

Visser reportedly suffered injuries in the fall -- and while details on his condition are unclear, doctors on the scene determined he was too hurt to fight and called off the bout.

It's a big bummer for the South African boxing community ... the tilt between Visser and Fick was reportedly set to be the first heavyweight title fight in Cape Town since 2000.

"I believe this fight is not going to go the distance, the person who has the bigger will is going to win this fight," promoter Jack Brice told IOL leading up to the fight.

"It’s good for Cape Town, it’s good for South Africa, and it’s good for boxing."

Unclear if or when the two will reschedule the match ... we're still waiting on word for just how injured Visser was in the fall.

We're told Jason went under the knife Thursday night and just hours after the band was forced to postpone a show in Duluth, Minnesota. The band, naturally, was there at the hospital to support Jason.

Seems Jason's gonna recover just fine ... and fans who missed out on the show should not fret. The rep tells us 5FDP will be rescheduling affected shows.

The band's currently near the end of its U.S. tour leg. Just 2 other gigs remain -- at CHI Health Center in Omaha, Nebraska on Saturday and Wells Fargo Arena in Des Moines, Iowa on Sunday.

Gruesome night in the OHL on Thursday ... a goalie was cut so severely by a skate -- blood poured onto the ice and the guy needed emergency surgery to save his life.

It all went down in Canada ... where during the 2nd period of the Niagara IceDogs' game against the London Knights, a player slammed into IceDog goalie Tucker Tynan.

The collision wasn't too violent ... but after a few seconds, it became clear something was VERY wrong -- because blood began to profusely pour out of Tynan's leg.

The 17-year-old was tended to by trainers for roughly 10 minutes on the ice before he was rushed into emergency surgery. The game, meanwhile, was immediately canceled.

The IceDogs announced the surgery was serious ... but thankfully, they said Tynan pulled through and is now "stable and safe" in a local hospital.

The scene after Tynan left the ice was pretty gnarly ... you can see in a picture of the aftermath, a portion of the crease was soaked in blood.

Teammates quickly showed their support for Tynan on social media, with stud forward Jonah De Simone writing, "The boys are here for you Tucks, keep strong."

Ex-NBA commissioner David Stern suffered a "sudden brain hemorrhage" on Thursday and underwent emergency surgery, the NBA announced.

77-year-old Stern collapsed at the Brasserie 8 1/2 restaurant in Manhattan while dining on Thursday, according to ESPN's Adrian Wojnarowski.

Stern was rushed to a nearby hospital where he underwent emergency surgery.

Stern served as NBA commish from 1984 to 2014. He famously shook LeBron James' hand when he was selected with the #1 overall pick in the 2003 NBA Draft.

He was the 4th NBA commish and current NBA commish Adam Silver was his protege.

The NBA hired Stern in 1980 as the Executive Vice President after he put in 2 years as the league's general counsel.

Stern famously implemented the NBA's dress code which required players to wear business casual attire to games. It also required players to wear a sport coat and dress shoes while on the bench (if that player wasn't active for the game).

Stern is married to Diane Bock Stern and they have 2 adult sons together, Eric and Andrew.

During his run as commish, Stern helped launch and grow the WNBA.

But, ref Lewis Garrison accidentally got in the way ... and took a BIG elbow right to the face.

Garrison dropped to his knees and had to be helped off the floor ... and after trainers checked him out at the stadium, he reportedly went to a local hospital for further evaluation.

Thankfully, doesn't seem Garrison's injuries are too serious ... it's reported the trip to the emergency room was for precautionary reasons -- but still, scary stuff!!

As for the game, Cockburn ended up leading Illinois to a huge 71-62 win over the Wolverines -- a massive upset.

French Montana is back on the social circuit ... hitting up a hot WeHo restaurant Monday night ... resurfacing in public after a prolonged, scary hospital stay.

French grabbed dinner with his pal, Megan Thee Stallion, at Catch restaurant. They arrived and left separately.

TMZ broke the story ... French was rushed to the hospital last month with an undisclosed illness ... with symptoms that included severe stomach pain and an elevated heart rate. He believes the problems surfaced as a result of seriously overworking.

He was laid up in ICU for 7 days before being moved to a private room. In all, he was hospitalized for nearly 2 weeks.

Doctors have ordered French to bed rest for 30 days. He's allowed to grab some grub, but no working, traveling, exercising, performing or partying ... though, since his new album, "Montana," just dropped.

The California inmate accused of stabbing Sirhan Sirhan in prison has been hit with an attempted murder charge, but if he's convicted he won't lose any sleep over it.

We broke the story ... Robert F. Kennedy's assassin was attacked at California's Richard. J. Donovan Correctional Facility in August by an inmate, and his injuries were so bad he was removed from the state prison for treatment.

Sirhan claimed the assault was random, and the suspect came from behind and slashed him with a blade across the left side of his neck, right below his ear.

According to new docs, the attacker is -- just like Sirhan -- a lifer named Steven Maurice Miko.

Miko's already gonna be locked up for the next 4 centuries for a crime spree in 2000. Now his rap sheet will include 2 more charges ... attempted murder and assault by a prisoner serving a life sentence.

In the docs, obtained by TMZ, prosecutors say Miko tried to kill Sirhan by inflicting great bodily harm on him. If Miko's convicted he's facing ... well, it doesn't really matter what he'd face. He's only 17 years into his 432-year sentence.

As we told you ... Sirhan recovered from the stabbing and was placed back in the prison. He was convicted in the fatal shooting of RFK in 1968 during a campaign rally in L.A. He was initially sentenced to death, but that was later commuted to life in prison.

A woman on a United Airlines flight got wayyy more than a trip from point A to point B ... ending her journey instead with burning pain from multiple scorpion stings.

The woman says she was on a flight from San Francisco to Atlanta Thursday morning. She says while in the air, she began to feel a stinging sensation on her leg and went to the restroom when it intensified.

The woman says that's when the scorpion dropped out of her pant leg, still alive, and scurried across the floor. It was eventually caught by flight attendants.

Paramedics met with her once the plane landed to tend to her multiple stings. Luckily she's going to be just fine.
