Nurse!

TMZ has obtained video of the accident that left Paz de la Huerta with a broken back that derailed her career.

The video was shot on the set of "Nurse 3D." You see Paz walking across a street -- umbrella in hand -- when the side mirror of an ambulance nails her, sending her crashing to the ground.

Paz filed a lawsuit against Lionsgate for $55 million, claiming the 2011 accident left her unable to work and permanently hurt. She had to have surgery to correct a spinal fracture.

The video will be the centerpiece of her trial. She's due in Santa Monica court Tuesday because Lionsgate is trying to get the suit dismissed.

"Teen Mom 2" star Jenelle Evans is desperate to find out why she keeps landing in the hospital ... and she's flown cross-country to figure out what's wrong with her.

We got Jenelle right after she arrived at LAX. She told us she's meeting with specialists to figure out why she's having joint pains and severe hot flashes at just 24 years old.

We asked if she'd been stressed while shooting a new season of 'Teen Mom' and Jenelle's response is interesting. At this point, there's no guarantee she'll stay on the show.

"Hollywood Divas" star Elise Neal says she bailed on her show after equipment busted her head open during a shoot, and producers refused to foot the medical bills.

Neal tells TMZ she was taping a scene at a bowling alley when a light fixture broke and knocked her in the head.

Neal says producers were heartless and told her she needed to finish shooting the scene. She claims production tried to cover up the accident and then just filmed like it never happened.

According to Neal, "Hollywood Divas" has refused to pay a cent of her sizable medical bills, which include the cost of x-rays and MRIs.

We reached out to the show's producers ... so far, no word back.

"Mobwives" star Angela "Big Ang" Raiola is still alive and surrounded by family members at a Manhattan hospital despite multiple reports saying she died ... this according to a statement from a rep.

Outlets reported Ang had passed away after a battle with cancer around 6 PM PST but according to a statement on her Twitter, Ang is still alive. Addressing the death reports, the statement says, "All of the media outlets currently reporting this are reporting FALSE INFORMATION."

TMZ has spoken with a family member at Raiola's bedside who confirmed the statement. We're told her estranged husband Neil Murphy is with Ang.

The statement goes on ... "Angela is still in the hospital surrounded by her loved ones, and is fighting. Thank you."

Somebody get Maverick on the horn ... Val Kilmer appears to be on the road to recovery, and ready for a wingman.

Val was spotted at Heathrow Airport Wednesday, looking the best we've seen him in a long time. You'll recall, about a year ago he was getting treatment for what doctors suspected was a tumor on his throat -- and he's rarely been seen in public since then.

He's been taking in some London plays recently and touring art galleries.

Big Ang is fighting stage 4 cancer all on her own, and wants it that way -- she got emotional about ending her marriage during an appearance on 'Dr. Oz.'

The "Mob Wives" star revealed why she was splitting from Neil Murphy, husband of 6 years, and made it clear "it's too late" to repair the relationship.

As TMZ first reported ... Ang has been experiencing severe pain lately as she battles cancer, and her family is trying alternative treatments to manage the pain.

On Tuesday's episode of 'Oz,' she also said doctors have given her a 30 percent chance of survival.

Jay Rock, a member of the TDE crew with Kendrick Lamar, was involved in a bad motorcycle accident Monday night while his pal was cleaning up at the Grammys.

Tiffith says Jay Rock suffered several broken bones and is hospitalized, but conscious.

TDE President Punch also posted an update saying Jay Rock will recover from the accident.

Barry Manilow has been muzzled by his doctors who have zipped up his grill and banned him from spittin' rhymes.

Barry's on the mend after undergoing emergency oral surgery. He apparently had surgery on Monday but there were complications and he was rushed back Thursday night from Memphis to L.A. for the procedure.

The "Mandy" singer's publicist said, "For the next 48 hours, Manilow has been instructed not to talk, sing or rap."

There goes 4-bar Friday.

Harrison Ford's busted leg on the set of 'The Force Awakens' just got the 'Star Wars' production slapped with 4 criminal charges in England.

The U.K.'s Health and Safety Executive brought the charges against Foodles Production Ltd. -- a Disney subsidiary -- claiming it violated health & safety codes when Han Solo went down during filming.

Back in June 2014 ... a hydraulic metal door on the Millenium Falcon slammed on Ford at Pinewood Studios. Foodles will have to face the judge in May.

Good thing they didn't see what happened to Han later during filming!

USC athletic director Pat Haden was taken away from USC by ambulance moments ago after a medical emergency outside of the athletic facility.

We spoke with USC's sports information director who tells us ... "Pat didn't collapse. It was similar to the Notre Dame incident."

"He felt lightheaded. We sat him down. We got medical personnel. He was alert."

"At one point, we walked him to his office and we got him some hydration. The ambulance came and transported him to seek medical assistance. I'm not sure if he was taken to a hospital or his personal doctor."

As we previously reported, a USC journalism student reported at least one student saw 63-year-old Haden collapse.

USC journalism student Kelly Reinke tweeted, "Annenberg student sees @PatHadenSC carried to ambulance on stretcher outside Heritage Hall."

Back in October, Haden was hospitalized before the USC vs. Notre Dame game after feeling lightheaded.

He recently announced he would be stepping down from his position so he could spend more time with his family.

"Love & Hip Hop: NY" star Tahiry Jose says the brutal attack by a man backstage at a 2014 NYC fashion show left her $31k in the hole from medical bills and she's suing to get it back.

Tahiry just filed new legal docs in her suit against Carlos Fiasco, the man who copped a plea deal and got off with no jail time, and the fashion show and theater where the assault took place.

In the docs, she lists off her injuries from the assault -- cervical sprain, several disc injuries, wrist derangement, concussion and post-traumatic headaches. She says the pain got so bad she needed an epidural.

Tahiry says she had to drop $8k just for a neurologist and $5.5k for rehab. She's suing for her total medical bill -- the $31k -- plus damages for suffering and loss of enjoyment of life.

8:30 AM PT -- DMX denies taking any powder or drugs. He says all he remembers is having shortness of breath after suffering bronchitis for a couple of days.

A family member says X asked for his inhaler (for asthma) right before he fell unconscious. They were not able to get it to him in time. He's still in the hospital.

DMX was at death's door Monday night, not breathing, without a pulse and the signs point to an overdose.

It's a lot worse than the story DMX's people were putting out ... that he suffered an asthma attack.

Yonkers cops responded to a call about an unconscious male at a Ramada Inn just after 6 PM. We're told when cops arrived DMX was on the ground in the parking lot next to a parked car. Cops quickly determined he was lifeless, not breathing with no pulse and immediately began CPR.

After a minute of CPR X's pulse came back.

A witness on scene told cops DMX had ingested some sort of powder before lapsing into unconsciousness. Cops gave him Narcan, an antidote to narcotic ODs. DMX became "semi-conscious" and was taken to the hospital.

We're told DMX appears to be in stable condition and at this time, no criminal charges are expected.

Short story ... cops saved his life.

Zsa Zsa Gabor was rushed to the ER Monday ... 2 days after her 99th birthday, TMZ has learned.

Gabor was having difficulty breathing ... husband Frederic von Anhalt tells us.

Zsa Zsa's doctor came to her home and removed mucus from her throat, but it didn't cure the problem. Zsa Zsa was admitted to an L.A. hospital Monday morning.

Docs determined she has a feeding tube-related lung infection.

We're told Zsa Zsa's scheduled to undergo surgery to have her breathing tube removed.

Gabor has made frequent trips to the hospital over the last decade. Her right leg was amputated in 2011.

Salma Hayek got a helping hand from a couple of ER docs after getting rushed to the hospital in the coolest, most totally inappropriate shirt.

She's gonna be fine -- sounds like she bumped her head during a shoot -- but it might be a while before the doctors recover from seeing her in a t-shirt that makes it look like someone's got a handbra on her ample jugs.

Salma thought it was funny though ... she posted the pic. Breast ER visit.

Seconds after that massive crane came crashing down in NYC ... first responders were on the scene fighting to pull victims from their cars.

TMZ has obtained video of the rescue efforts. The crane, which is longer than a city block, took out multiple cars in TriBeCa.

There's an unknown number of people injured. The 1 person who was killed was apparently a pedestrian who was struck by the crane. We've blurred an image of the victim.

You can see the crane actually falling ... in this video.

Johnny Manziel's father says he's tried to get his son into rehab TWICE in the past week -- but Johnny refuses -- and now he's concerned he could die if he doesn't get help, asap.

Paul Manziel spoke with the Dallas Morning News and said, "I truly believe if they can't get him help, he won't live to see his 24th birthday."

Paul told DMN his family first tried to admit 23-year-old Johnny to the Enterhealth Ranch addiction facility in Van Alstyne on Saturday (after the incident with Colleen Crowley) -- but he refused to stay.

On Tuesday, Paul Manziel said he tried a second time ... begging his son to enter the Carrollton Springs Hospital ... which specializes in treating patients who suffer from mental illness and/or addiction.

Again, Johnny refused to stay ... Paul says.
