Nurse!

Rob Kardashian is in a vulnerable place right now and Blac Chyna not only knows it, she's taking full advantage ... according to people in Rob's inner circle.

Sources tell us Rob's close friends and family members tell us he's dealing with so much right now -- his ongoing weight issues and his recent diabetes diagnosis -- and they think BC made her move now, because his guard is down.

We're told they think Chyna really only wants 2 things: publicity and to get back at Kylie Jenner for hooking up with BC's baby daddy, Tyga.

Our sources say Rob's peeps think the fact Chyna's BFF Amber Rose just started following Scott Disick on IG ... is more proof this is a full scale "thirsty" attack.

They're all for Rob "having some fun" -- but they just hope he sees BC for what she is.

Jason Pierre-Paul just posted a photo that was taken at his hospital bedside on July 5th -- one day after the fireworks accident that blew up his hand.

JPP wrote, "July 5th I remember."

In the pic, you can see the NY Giants star elevating his right arm -- which is heavily wrapped up and red from the bleeding. You can also see blood on his hospital gown.

Miraculously, JPP not only recovered from the injury -- but eventually got back on the field and played with the Giants ... turning out a pretty impressive performance considering the circumstances.

In fact, the last time we spoke with JPP, he was in such good spirits about his situation -- he even joked about not being able to play video games anymore.

Kristin Cavallari was taken to a hospital outside Chicago after a car wreck.

Sources close to the reality star say she was in a vehicle that was struck by another driver Thursday afternoon. A witness tells us Cavallari's husband, Jay Cutler, showed up at the hospital shortly after she got there.

We're told Kristin's injuries aren't serious but she's sore. Her 3 kids weren't with her during the accident -- our source says cops are at the hospital to take a report.

"Little Women: LA" cast member Christy McGinity Gibel is in the hospital after a brutal attack by two of her cast mates.

The attack went down at Borderline Bar & Grill in Thousand Oaks, CA over the weekend while the cast was filming season 4. It's unclear what started the brawl, but Christy left with 2 brain contusions.

Christy couldn't shake the headache, so she checked herself into Cedars-Sinai Medical Center.

No word on what triggered the brawl... our source says the ladies were drinking iced tea, so alcohol doesn't appear to be a factor. We haven't been told which cast members brawled with Christy.

We got Christy's husband Todd as they left the hospital. He says she'll pull through, but she'll feel the effects for months.

Jason Mraz got in a serious accident after a driver sped through a red light and crashed into him.

The other driver t-boned Jason's car and then spun 90 degrees, striking another car.

Jason complained of neck pain but didn't go to the hospital. The female passenger in his car had more serious neck pain and was taken by ambulance to Tri-City Medical Center in Oceanside.

Jason had just left Home Depot when he got hit.

Rob Kardashian's diabetes diagnosis did not scare him healthy ... not by a long shot ... and his family is worried sick if he doesn't radically change his ways he could die.

Our Kardashian sources tell us they were confident after Rob was admitted to the hospital late last month and diagnosed with type 2 diabetes he'd begin eating healthy, exercising and doing whatever it took to beat the disease.

It's so bad, Rob has to give himself insulin injections once a day ... but he's still unfazed by the scare.

Our sources say he's still eating crap and not seriously doing anything to lose weight.

We're told Kris and Rob's sisters have stepped up and hired a full-time chef who specializes in diabetes diets to prepare all of his meals. They've also hired a nutritionist and trainer.

"The Sandlot" star who has been charged with felony assault helped beat a grad student within an inch of his life ... according to new legal docs.

Michael Vitar, who played Benny "The Jet" Rodriguez in the flick, allegedly attacked the 23-year-old USSB student on Halloween night.

According to a search warrant obtained by TMZ, 2 of Vitar's friends, both of whom are firefighters, spotted Samuel Chang passing out candy in the street of his gated L.A. community. The firefighters suspected Chang was passing out tainted candy and confronted him.

The warrant claims the 2 firefighters began beating on Chang, restraining him with a chokehold. The legal docs claim Vitar -- now a firefighter as well -- joined in, mid beating.

The warrant says the beating was so bad Chang's pulse stopped and the firefighters had to get their gear and revive him.

Chang was taken to the hospital with horrific injuries, including burst blood vessels in the eye, bleeding on the brain, kidney failure and hemorrhaging due to suffocation.

Chang had recorded the audio of the beating on his cell phone, and cops believe they can hear Vitar say, "I got the legs."

The student says he smelled alcohol on the breath of one of the firefighters. The firefighters told cops they believed Chang was under the influence of PCP, but doctors found no drugs in his system.

5:15 PM PST -- A source close to productions confirms the two involved in the lawsuit had no affiliation with the show and have never been on it.

A guy with a bum kidney who worked at Kleinfeld Bridal -- the store featured on TLC's smash hit, "Say Yes to the Dress" -- claims he was savagely beaten on the stairs going into the store, and he's filed a bridal brutality suit.

William Martinez claims he worked for Kleinfeld from 2011 - 2014 and everything was hunky dory until his last year on the job, when he was hospitalized with kidney problems and it left him unable to do the various physical tasks he was assigned.

Martinez says he went to one of the managers -- Manny -- and said he needed to be reassigned to clerical duties, but Manny kept making him do heavy lifting and later, told him to just "go the f*** home."

According to the lawsuit, Martinez told Manny he was going to file an HR complaint, and Manny responded by pushing him into a chair. Martinez finally left but when he came back he says Manny, with the help of a posse, took his cane away and beat the crap out of him.

Martinez says he was hospitalized and then fired by HR.

He's suing under the Americans with Disabilities Act for all sorts of money.

"Teen Mom 3" and "16 & Pregnant" star Mackenzie McKee is in the hospital for diabetic complications ... TMZ has learned.

Sources close to McKee tell us her mom and husband Josh rushed her to a hospital Wednesday night near their home in Miami, Oklahoma. We're told she was violently throwing up all night.

We're told Mackenzie discovered her blood sugar was "dangerously high" after testing with a home kit last night. They decided she needed to get to a hospital around 10 PM.

She is still there, and doctors are trying to stabilize Mackenzie's sugar levels.

Mackenzie has been training and dieting to compete in her next figure competition and that could have been a factor.

Mackenzie has had trouble controlling her blood sugar in the past ... she claims it caused a car accident last year.

Pacman Jones can hold on to that Oscar ... or Grammy ... 'cause Antonio Brown's father insists his son is NO ACTOR ... and didn't fake hurt after taking that shot from Vontaze Burfict.

TMZ Sports spoke with Eddie Brown who tells us he has already checked in with the Pittsburgh Steelers receiver to make sure he's okay after taking a shot to the head during Saturday's playoff game.

"He is doing well. I talked to him but I didn't go into detail. I just wanted to make sure he was okay. That was my biggest concern as a father and parent."

We asked what he thought about Pacman accusing his son of faking hurt -- and Eddie told us the thought of Antonio bluffing an injury is simply unfathomable.

"It's not in his character. I don't have to defend him because you can just look at his track record. Check his and then check the track record of the ones accusing him ... he's taken big hits before and he's gone right back to the huddle."

We also asked if he thought Burfict should be punished by the league for the hit:

The San Francisco 49ers booted a fan and his service dog from Levi's Stadium which made the fan have a seizure ... according to the lawsuit he's now filed against the team.

James Hilburn says he and his Alaskan malamute, Bear, had no problems entering the Niners-Cardinals game on November 29 -- the ticket taker let them in, no questions asked. In his suit, Hilburn says he suffers myoclonic dystonia ... which causes seizures. Bear is trained to alert him and people nearby when one is about to hit.

In the lawsuit, James says once he entered the staidum, police and security guards surrounded him and said Bear was not allowed to be there -- and the stressful situation triggered a seizure.

TMZ Sports obtained video Hilburn's friend shot, and you can hear Bear yelping a warning. Police and stadium staff attempted to get a shuttle to pick them up, but Hilburn declined. He did end up suffering, and had to be hospitalized, according to his lawyer Mark Thomas.

Hilburn wants the team to pay for violating the Americans with Disabilities Act.

We reached out to the 49ers who told us they do not comment on pending litigation.

Rob Kardashian was diagnosed with diabetic ketoacidosis ... this according to our Kardashian sources.

TMZ broke the story ... Rob was taken to an L.A. hospital Sunday after feeling terrible all weekend.

Our sources say after a battery of tests, Rob was diagnosed with diabetic ketoacidosis, a serious complication of diabetes that occurs when someone's body produces high levels of blood acids, or ketones.

Rob had no idea he was diabetic, and it's a good thing he took precautionary measures. If untreated, the condition can lead to a diabetic coma.

But there's good news ... our Kardashian sources say the doctors told Rob if he eats well and leads a "healthy lifestyle," he can actually get his diabetes, which is type 2, under control and potentially have it go into remission.

Rob is back at home and resting, and this may be just what the doctor ordered -- literally -- to get him back on the right path.
