Nurse!

Justin Bieber had a needle in his arm as he walked the streets of Beverly Hills, but it's actually the picture of health.

Justin cruised out of a medical building Wednesday and Thursday with an IV bag, our sources tell us he was there for a vitamin drip.

In case you didn't know ... aside from curing hangovers, vitamin drips improve immune health, boost energy levels, abate depression and anxiety, improve mental clarity and cognative function, reduce migraine symptoms, combat fatigue and maintain muscle strength.

And, there's more TMZ-MD, the IV's typically contain high doses of vitamin C or magnesium.

One treatment often costs around $120.

It's not without danger. Kendall Jenner was hospitalized last year after she had a bad reaction to a vitamin IV drip.

Dog The Bounty Hunter believes his weekend hospitalization was caused from a broken heart suffered from the death of his wife, Beth.

Dog described the sensation as an intense pain in the center of his chest -- a feeling like he'd just run 3 or 4 miles -- even though he only did a simple workout. He told FOX31 Denver he could barely breathe and knew something had to be done quickly ... so his assistant took him to get help.

Halfway through the interview, Dog breaks down a little bit, saying he believes the leading factor behind his chest pain was that he'd suffered a broken heart.

TMZ broke the story ... Dog was rushed to a hospital over the weekend for what was first thought to be a heart attack. Docs ran tests and determined that not to be the case ... and Dog's family has stressed the importance of living a healthier lifestyle since the incident.

Dog's wife Beth died in June after a long and hard-fought battle with cancer. Beth will be heavily featured in the upcoming series "Dog's Most Wanted" on WGN America. The show was shot right up until her death and profiles her battle with cancer.

The woman suing Chris Brown over eye injuries she allegedly suffered on a music video shoot has a photo of her puffy peepers ... and it'll make you go, "ewwwww."

In the photo -- obtained by TMZ -- Danielle Griffin's eyes appear red, swollen and caked in a gross, greenish goop. We're told that's pus discharging from her eyes, so like we said ... eww.

Griffin claims in legal docs ... she was hired as a backup dancer in September 2017 to perform in a CB music video, which was shooting in Downtown L.A.

According to the suit ... sometime during the shoot, a wardrobe and makeup artist poured fake liquid blood on her head without eye protection and told her it was safe. Griffin claims it wasn't ... and the "dangerous substance" caused direct injuries to both of her eyes.

Griffin's attorney -- Arshia Mardasi of Allen, Flatt, Ballidis & Leslie -- tells us she had to go to 3 different hospitals in 24 hours to tend to her eye injuries. Mardasi says Griffin was also holed up for months while she recovered, which caused her to drop out of her master's degree program and miss several job opportunities.

We are told the music vid she was hired for was "High End," which features Future and Young Thug.

Dog the Bounty Hunter understands he might need to make serious changes in his day-to-day life if he's going to be around for his family ... this after some tough love.

Sources close to Dog tell TMZ ... family members had a serious talk with him after his weekend hospitalization -- for what seemed like a possible heart attack -- and made it clear something's gotta give.

As we reported, it turned out to to NOT be a heart attack ... still, we're told Dog seems open to making some changes, but nothing is gonna come easy.

For starters ... he has been and continues to be a heavy smoker, which of course, is a leading cause of heart issues. We're told he's willing to try to cut back on cigarettes, but there's no talk of quitting.

TMZ broke the story ... after performing a bunch of tests, doctors determined Dog's chest pain was brought on by stress and blood pressure issues.

Our sources say Dog eats a ton of junk food -- so he's open to dietary changes as well. He's been very candid about his loss of appetite since Beth died -- but his family wants him to commit to getting on a strict and healthy diet.

We're told the family's hoping the health scare will shock Dog into making what they feel are the necessary changes.

Dave East isn't celebrating the fact he scored a three-way in Vegas ... instead, he's facing a battery charge after cops say bottles and punches were thrown while he was in the act.

The New York rapper was cited last weekend in Las Vegas after cops interviewed multiple witnesses to an altercation he and 2 women allegedly got into following an appearance Saturday night at Drai's Nightclub.

According to the police report, obtained by TMZ, Dave invited 2 women back to his room at the Delano hotel and started having sex with them. From Dave's POV, he told officers that 1 woman was upset he wasn't giving her as much attention ... and flipped out.

Dave told cops she started hurling champagne bottles at him from across the room, and 2 of 'em made contact ... striking him in the head and leaving cuts -- which cops saw -- on his arm and leg.

As for the woman's version ... she told officers that in the middle of the sexual encounter, she and Dave got into an argument, and he threw punches 5-6 times, with one hitting her arm. She said she ran to the bathroom to call cops. She made no mention of bottles being thrown.

Other witnesses included a third woman who entered the room once the argument started and one of Dave's friends. The woman said Dave was the aggressor, while his buddy only saw the woman hurling bottles. Obviously, a he-said, she-said situation.

Both parties were cited for misdemeanor battery, but nobody was arrested. Dave and the woman were treated at separate hospitals.

Dave's attorney, Stacey Richman, further claims the woman threw a soap dispenser at Dave -- but says the rapper didn't respond with violence, and instead was concerned for everyone's safety. Richman claims Dave justifiably took her by the arm and put her out of the room.

Dog the Bounty Hunter did not have a heart attack over the weekend, but he's not in the clear either ... sources connected to Dog tell TMZ.

We're told doctors performed a bunch of tests and say the episode over the weekend that landed Dog in the hospital appears to be stress and blood pressure-related. But, thankfully, we're told doctors are confident it was not a full-blown heart attack.

What's more ... doctors performed an angiogram and it was normal.

Dog's family is worried about him. They say he has had trouble handling the stress associated with Beth's death, a subsequent burglary and various other issues. It's all been exacerbated by high blood pressure, and the chest pains he experienced over the weekend were scary and a cumulative effect of all these events.

The good news ... one source said Dog was released from the hospital late Monday night, and is now resting at home.

Dog the Bounty Hunter was hospitalized this weekend after suffering a heart emergency that may require surgery -- this just a couple months after his wife, Beth Chapman, died.

Sources tell TMZ the reality TV star was taken to a hospital from his home in Colorado after feeling a pain in his chest.

They're also trying to figure out if he will need a corrective surgery.

Either way ... it's a scary incident for the Chapman family coming just a few months after Beth died from cancer.

Beth's death has been incredibly hard on Dog -- he broke down in tears at her Colorado memorial -- who's also been dealing with other forms of stress lately.

His store was broken into last month -- where crooks made off with some of Beth's personal items -- and Dog also nearly fell victim to a $430k check scam out of Dubai.

Couple that with the recent premiere of his new show and the countless promotional stops that required, and it's obvious Dog's been under a lot of pressure lately. How much that factors into his heart emergency remains to be seen ... but it certainly couldn't have helped.

Get well soon, DBH.

Say what you will about Tyson Fury ... but the dude is tough as nails -- battling through a massive gash over his eye to beat Otto Wallin on Saturday ... and then getting 50 STITCHES after the fight!

Check out Tyson's before and after pics ... Fury had TWO gashes on his face -- one on his eyebrow and one on his eyelid.

Wallin opened up the bigger gash with a flush shot to Tyson's face in the 2nd round of their heavyweight championship fight in Vegas on Saturday.

Throughout the fight, Wallin targeted the wound -- and it took every drop of Vaseline in Nevada to keep the wound in check so Fury could continue fighting.

A second gash opened up later on ... and it REALLY seemed as if the ref and ringside doctor would stop the fight -- but somehow, they let Fury finish.

Fury ultimately won in a unanimous decision and went to the hospital right after the event -- where docs used 50 stitches to close him up.

Gotta say ... props to the docs -- they did a pretty great job!

Mike Posner won't let a near-fatal rattlesnake bite keep him from completing his walk across the U.S. of A. ... because the dude's back on the trail and more determined than ever!!!

The "Cooler Than Me" singer hopped on "TMZ Live" Thursday as he continued his journey from New Jersey to California, detailing his scary encounter with a rattler that nearly took his life.

Mike describes his injury in excruciating detail ... explaining how the baby rattlesnake's venom coursing through his veins had him feeling like he was in the closing credits of a "Looney Tunes" cartoon. Really paints a picture.

Remember ... a rattler tore into Mike's foot last month, after walking 16 miles through the middle of nowhere in Colorado and looking to log 8 more. The bite was as bad as it looked. Mike was airlifted to a hospital and placed in ICU for days, putting his trip across America, like his foot, on ice.

But, Mike's no quitter ... he's picking right up where he left off -- the site of the snake bite -- and says he even saw a few more rattlers on his way toward Arizona.

Mike appeared last April on "TMZ Live," telling us how the deaths of his father and Avicii inspired him to cross the country on foot.

Mike's been releasing new music along the way -- every time he crosses a state line -- and when he gets to Arizona in a few days, he's got a new song -- "Slow It Down" -- for his fans.

Mike feels anything but snake bitten.

Need proof Kevin Hart's gonna pull through after a devastating car crash? Look no further than his wife ... 'cause she sounds incredibly optimistic.

Eniko Hart was leaving a Starbucks Thursday in L.A. and the obvious question ... Kev's prognosis. TMZ broke the story ... Kevin was released from the hospital Wednesday and he checked in to a live-in rehab facility, telling friends he was grateful to be alive. That said, he's staring down at least a week in the new facility and months of outpatient rehab.

As you know ... Kevin, a driver and another passenger careened into a ditch in Malibu a week ago Sunday, and he fractured 3 areas of the spine. He had those 3 areas fused during surgery.

Eniko knows the road ahead will be tough, but she's got a lot of pep in her step and is super upbeat.

Kevin Hart is out of the hospital, TMZ has learned, and he's now at a live-in rehab facility doing intense physical therapy to recover from his car crash injuries and surgery.

Sources with direct knowledge tell us, Kevin is "glad" to get out of the L.A. hospital he's called home for 10 days. He has a positive attitude, saying, "I'm grateful to be alive."

He's at the rehab joint right now, and the goal we're told is to get him home "as soon as possible," where he can start outpatient care.

Realistically, our sources say he's looking at around a week -- more or less -- at the live-in facility.

Great news!!!

Oakland Raiders star cornerback Gareon Conley tells TMZ Sports the X-rays on his neck, following that scary injury on "Monday Night Football," came out good ... and he expects to play next week!

Conley was laid out on the field for roughly 10 minutes after suffering a neck injury while trying to tackle Denver Broncos running back Royce Freeman.

It appeared Conley took heavy impact from hard-hitting Raiders' teammate Johnathan Abram -- who assisted on the tackle. Conley was eventually carried off the field on a stretcher and taken to a nearby hospital for treatment.

We reached out to Conley's camp on Tuesday to see how he was doing, and he sent us back a video telling us he got great news from the doctors!

"I had X-rays and everything on my neck. Everything came out good," Conley says ... "So, I'll be ready to play next week, man. I'm good!"

Conley also thanked all of the fans who kept him in their thoughts and prayers.

The Raiders dominated the Broncos on 'MNF' earning their first win of the 2019 season.

Kevin Hart is chomping at the bit to get out of the hospital, and our KH sources say that will happen as early as Tuesday.

Kevin's been hospitalized for 9 days since his horrific car crash that left him with 3 spinal fractures which had to be fused in surgery.

Our sources say Kevin's crossing his fingers that doctors release him Tuesday, but if that doesn't happen it will definitely happen Wednesday.

Kevin will be taken to an inpatient physical therapy facility where he will spend 1 to 2 weeks before he comes home.

As for his progress ... we're told he's taking short walks in the hospital and can even climb a few steps. He's getting PT in the hospital but it will be more intensive in the rehab facility.

Robin Thicke and his fiancee were just involved in a car accident that sent one vehicle flying into the side of the road in Malibu -- but it appears everyone's alright.

Eyewitnesses tell us the singer was riding passenger in an Escalade Saturday along PCH in Malibu near Point Dume and Zuma Beach. We're told a woman who was driving -- which we've confirmed was his fiancee and baby mama, April Love Geary -- somehow collided with another car full of what we're told were younger people.

Eyewitnesses say that Robin got out of the SUV and walked over to the other vehicle, which was lying on the side of the highway ... nearly tipped on its side. Luckily, this looks a lot worse than it actually was, as nobody seems to have suffered major injuries.

Law enforcement sources tell us no one was transported to a hospital in the two-vehicle collision, and that a report was taken on the scene. Fault will be determined at a later date.

In video of the scene, obtained by TMZ, you see Robin picking up car parts off the road and attempting to direct traffic away from the accident. At one point, you see Robin's SUV pulling out ... and the extent of the damage on it is on full display.

Based on what Robin posted on IG a little while ago, it doesn't appear their kids were with them -- looks like he and April did a solo lunch date, and they both seem okay.

Kevin Hart is already back on his own two feet -- but he's miles away from a full recovery ... TMZ has confirmed.

Sources connected to the comedian tell us that Kevin is, in fact, walking again -- as Tiffany Haddish mentioned Friday at the Harper's Bazaar ICONS event in NYC -- but he's not nearly as "good" as she made it seem. We're told he's walking slowly and gingerly at this point.

We're also told KH's starting physical therapy this weekend at the hospital he's currently being treated at. That's great considering he just underwent surgery days ago.

While he may be taking steps in his road to full health, make no mistake ... we're told Kevin is in excruciating pain as he heals, but that he's also maintaining a relatively positive mood.

TMZ broke the story ... Kevin was involved in a nasty car accident last weekend that sent his 1970 Plymouth Barracuda flying into a ditch off a highway in Malibu Hills. He suffered 3 spinal fractures, and went into surgery soon afterward for his back.

Kevin Hart's scary car wreck has Dr. Phil shook because, like Kevin, he owns a classic car ... and he's now realizing it comes with some serious safety concerns.

The Doc tells "TMZ Live" his '57 Chevy is the same as Hart's 1970 Plymouth Barracuda in that it's equipped with lap belts but not safety harnesses ... and he doesn't know what to do about it.

As Dr. Phil says -- they don't make cars today like they used to ... and that's not always a good thing. He shows us there's really no way to easily install shoulder strap seat belts with the way the car's built. That's not the case with Kevin's Barracuda -- shoulder straps could have been installed.

Phil points out old cars like his and Kevin's don't perform nearly as well in crash tests as modern vehicles and, without making changes ... survival rates in crashes are much lower. In fact, he says he's stunned Hart is still alive.

As we told you ... Hart suffered serious injuries -- including 3 spinal fractures -- when his classic ride crashed through a fence on Mulholland Highway in the Malibu area early Sunday. The driver, his friend Jared Black, also suffered severe back injuries.

While their injuries may not have been totally avoided had the car been equipped with safety harnesses or airbags, they certainly wouldn't have hurt ... and installing them is now top of mind for Dr. Phil.
