Nurse!

There's no doubt Macklemore is lucky to be alive when you see what's left of his Maybach after a head-on collision with an alleged drunk driver.

TMZ obtained these pics of the wreckage -- Mack's 2016 Mercedes-Maybach is sitting in a tow yard now with tremendous damage to the front bumper, hood and engine. His driver and passenger side airbags both deployed.

We broke the story ... Macklemore was smashed by a pickup truck Friday night in Langley, Washington but walked away unscathed. His 2 passengers also escaped serious injury. Pretty good ad for Benz.

Mariah Carey's bodyguard dragged a guy out of the backstage area ... who claims he was a credentialed journalist -- but Mariah's team is calling BS.

James Pablo tells TMZ he was backstage at Mariah and Lionel Richie's show Thursday night at San Diego State's Viegas Arena to interview their opener. He says he had a press pass that was attached to a lanyard around his neck, and had every right to be there.

James says he saw Mariah backstage, and asked to take a pic with her -- which he says she OK'd. When he tried going in for the selfie, James says her bodyguard allegedly yanked his lanyard -- which was still around his neck -- and dragged him outside.

Once he was out, James tracked down cops and filed a police report ... saying he wanted to press charges. Law enforcement sources confirm a battery report was taken and the investigation is ongoing.

As for Mariah ... sources close to her tell us James was an obsessed fan who snuck backstage with a fake badge. Her bodyguard pulled James away when he saw him grab her dress and feared he was going to attack her.

James insists he had a valid press credential to be backstage, and denies grabbing Mariah's dress.

Venus Williams' car crash was a bloody, chaotic scene ... according to frantic 911 callers.

TMZ obtained the audio, and one witness emotionally described the accident with glass everywhere, and at least one person, Jerome Barson, left badly bleeding from his arm and leg. He died 2 weeks later from his injuries.

The caller also says Venus was able to get out of her car and walk, while Jerome and his wife, Linda were badly injured and unable to exit their vehicle. She eventually recognizes Venus, and says "she was unfortunately at fault."

As we first reported ... the attorney for the Barson estate -- which is suing Venus for wrongful death -- says vehicle data from Venus' SUV shows she went from 0 to 19.9 MPH in about 4.2 seconds as she tried to clear the intersection.

Cops on the scene said Venus was at fault in the accident, but did not cite her -- as seen in body cam footage.

The wisest part of getting your wisdom teeth removed is having someone record you when you're coming down off the drugs ... and Simone Biles knows it!

The Team USA Olympic gymnast hit the oral surgeon's office -- and after the procedure, she was OUT HER DAMN MIND!

At one point, Biles thought she was driving a truck -- and even honked the imaginary horn!

Good news ... she's fine now and even joked about it on social media.

"Hope yall get a good laugh!!"

Justin Bieber's accident with a photographer was, of course, captured on camera by the photog ... and we just got the intense footage.

You can see and hear the accident from the pap's view -- and you also see how Justin sprung out of the truck and ran around to check on the guy. The camera was still rolling as Justin knelt down and repeatedly asked, "Is there anything we can do to help you?"

Few moments of conflict too -- Justin was upset other photogs continued rolling, instead of helping the guy who'd been hit ... who, by the way, sounded very appreciative of Justin's concern.

You can hear him say, "I always liked you man. You're a good guy. It was just bad timing."

Justin Bieber accidentally ran over a photographer as he left a church service in Beverly Hills ... and the loud impact was captured on camera.

Justin was leaving the Saban Theater, where he'd been worshipping at a City Church event. He climbed into his monster pickup truck as photogs scrambled around the vehicle, and when he gunned it to pull away ... hit the man. It's pretty clear in the video ... Justin's front right side tire hits, or rolls over, the paparazzo.

Justin did not flee the scene and, in fact, stopped as soon as other photogs pointed out what had happened. Bieber stayed right by the man's side for roughly 8 to 10 minutes until paramedics and police arrived.

Justin spoke to police before he was allowed to leave the scene -- police tell TMZ he was not cited -- getting a ride from one friend, while another drove his truck.

Police say the photog suffered non-life threatening injuries to his lower body.

A few hours after he was taken to the hospital ... he posted a video describing the accident, and thanking Justin for being "compassionate."

William Shatner had a buck of a scare when his horse got spooked, and tossed him from the cart it was pulling.

Shatner was participating in a horse and buggy competition Wednesday at the Mercer County Fair & Horse Show in Harrodsburg, KY ... where he was entered on the amateur level.

As he turns a corner on the track, the horse suddenly reared up for seemingly no reason. The cart, called a sulky, Shatner was in flipped and he ate it. Sources at the event tell us Capt. Kirk and his steed were both uninjured. Bill didn't need medical attention, and even with the spill, took 1st place!

As a young star fleet Capt. once said ... hang on tight and survive, and then win.

Chicago Bears linebacker Jerrell Freeman says he nearly BROKE A MAN'S RIBS while giving him the Heimlich in an Austin airport ... but says he quick action saved the dude's life.

Freeman was on his way to the Bears training camp when he saw a guy choking on brisket at an airport restaurant and immediately snapped into action.

"I tried to squeeze the life out of him and bring him back," Freeman tells TMZ Sports.

At one point the man told Jerrell he thought he may have cracked a rib, to which Freeman responded -- "It's either one of your ribs or your life man! Gotta take one, leave the other one!"

In the end, Freeman says he successfully dislodged the food from the man's throat and the guy praised him as a hero and thanked him for saving his life.

Then he went back to eating his brisket.

Seriously!

Ronnie Magro from 'Jersey Shore' needed stitches to repair his sliced and bloodied hand after a rough night in a Las Vegas club.

TMZ obtained a shot of Ronnie's messed up left mitt -- he walked away from the fight with what looks like 5 lacerations. As we first reported ... Ronnie sustained the injuries early Friday morning in Tao Las Vegas.

Sources connected to Ronnie say he was in VIP when a crowd spilled into the area around him ... and as he tried to shield her, someone threw a bottle or glass which shattered on his hand. A rep for Tao tells a slightly different story -- saying there were no other individuals involved, and Ronnie just accidentally broke a bottle in his hand.

Either way, Ronnie didn't realize he was cut -- booze numbs, after all -- until his gf pointed out he was bleeding on her. Security at TAO gave him a few bandages and suggested he get stitches.

He initially blew off that advice, but we're told Ronnie gave in Friday afternoon and got stitches.

John McCain has been diagnosed with brain cancer.

Pathology was performed following McCain's surgery Friday to remove a blood clot, and tests showed the presence of a "primary brain tumor" known as glioblastoma.

The family is now considering treatment options with his Mayo Clinic team of doctors.

The 80-year-old Senator was resting at home following the removal of the blood clot last week. His absence from Congress led Republicans to defer the vote on the repeal and replacement of Obamacare.

His office did not reveal a prognosis.

A helicopter carrying Shane McMahon -- son of Vince -- crashed off the coast of Long Island Wednesday after the engine failed, but the WWE exec escaped unscathed.

FAA sources tell TMZ Sports the Robinson R-44 chopper -- with McMahon and a pilot onboard -- conducted an emergency landing after an the malfunction.

Shortly before ending up in the Atlantic, the chopper departed Westchester airport in NY.

We're told the pilot issued a mayday call prior to the crash landing. Once in the water, emergency crews responded and rescued the men.

McMahon, 47, is the Commissioner of "SmackDown LIVE."

The FAA is investigating the crash.

Footage from the alleged Ezekiel Elliott incident has emerged showing the victim beaten, lying in a pool of blood ... before being carried out of a Dallas bar.

In the video obtained by TMZ Sports, the victim -- moments after the alleged altercation -- appears unable to stand under his own power.

The witness who took the video tells us they saw Elliott and the man arguing, and then saw Zeke punch the guy in the nose ... sending him to the floor of Clutch Bar.

The account syncs up with what other witnesses have told us.

Dallas PD are currently investigating the incident. They have not named any suspects.

Elliott's reps have only said their client was not arrested ... or charged with a crime.

Here's a video of terrifying UFC destroyer Khabib Nurmagomedov punching an average dude in the stomach super freakin' hard ... but don't worry, the guy actually ASKED him to.

Now, why this dude wanted to get popped in the guts by a guy who wrestles bears for fun is beyond us, but it 100% happened when Khabib was messing around with some fans in Tajikistan.

We don't know what Khabib says to the guy before the punch happens, but he seems to be telling him how the shot is going to rearrange his organs before he hits him.

Good news? After he delivers the dragon punch to the dude's stomach the two men hug, which is great, but watching the whole thing made us happy we give hugs to bond on this side of the pond.

"American Idol" contestant Haley Reinhart's friend suffered horrendous injuries the night she was arrested after a bar bouncer put him in a choke hold and allegedly beat him.

TMZ broke the story, Haley was arrested for allegedly punching the security guard in the face, but she says she was just trying to get the bouncer to release what she thought was a death grip.

Haley's friend, Alan Chislof, suffered a concussion, facial laceration near his right temple, a bad cut above his left eye, facial bruising and hematoma. The choke hold caused blood to flow to his eyes and he looks like he went 5 rounds with Mayweather. He says he's coughing up blood and complaining of chest pain.

Chislof's lawyer, Mark Brown, now promises a lawsuit.

We also got video of the confrontation, and gotta say ... it seems to support Haley's version of events.

9:21 AM -- Ryan just tweeted the injury is the result of a freak accident, NOT an injury he suffered doing a stunt or anywhere near the set of "Shooter."

Ryan Phillippe's learning the hard way ... breaking a leg as an actor ain't always a good thing.

The "Shooter" star is laid up in a hospital bed with his right leg bandaged up -- also looks like he has a cast around his ankle. It's unclear what he broke, but based on the hardware fixed on the leg ... we're guessing there was some surgery involved.

No word if it's a work related injury, but Ryan captioned the pic, "I'm going to be ok and I appreciate your concern." A few hours later he changed his tune a bit, tweeting, "this sucks."

The 'Walking Dead' stuntman who fell about 25 feet off a balcony was bleeding from his head and nose after the impact ... this according to the 911 call.

TMZ has obtained the audio ... and the caller, an assistant director on set, says in the audio they need an ambulance ASAP after John Bernecker fell Wednesday afternoon. The caller told dispatch John's breathing heavily and they can't tell if he landed on his back or head ... but said, "his neck is in the position where he landed."

John was described as "barely conscious" at the time of the call. The caller did not say if they were shooting a scene at the time but AMC said it's temporarily shutting down production.
