Nurse!

Corey Harrison from "Pawn Stars" flung himself off a moving vehicle Saturday to avoid a MAJOR crash ... and the reality star miraculously lived to tell the tale.

Harrison's family and friends were throwing him a birthday party this weekend at his house ... but before the bash, he left on his motorcycle to grab a few supplies.

Corey says a piece of the bottom fender mount suddenly broke off ... sending his bike into a tailspin at 40 mph. The reality star was faced with two options -- fly into a nearby wall/oncoming traffic, or jump off the bike. He chose door #2.

Harrison was not about to let partygoers down ... so he chose to go to the party instead of the hospital. After the party he took a trip to the ER where he learned he had a broken hand. Doctors surgically placed 8 screws and 2 plates into his busted hand.

Corey couldn't celebrate the party he hoped to have Monday night at the D Hotel and Casino in Vegas ... so they ended up bringing the party to him ... at his humble abode.

Disgraced Los Angeles Clippers owner Donald Sterling has been battling cancer for several years, TMZ has confirmed.

Sterling's cancer medication, believed to be for prostate cancer, is what has caused his face to look puffy in recent years, says the New York Post. One source told the paper, "They thought he would die two years ago."

Clippers players were unaware of Sterling's alleged condition. Blake Griffin told reporters after last night's loss to the Golden State Warriors, "If that is true, my thoughts and prayers are with him. Nobody deserves to go through something like that."

Lisa Marie Presley has BACKED out of her remaining concert dates ... literally.

Presley has a bum back that has dogged her with chronic pain ... and she just can't stand it anymore ... because doing concerts is now excruciating.

It's not made up. We're told Lisa's doctor ordered her to pull the plug because he fears her condition will worsen with the strain of gyrating on stage -- just like her daddy did.

We're told her back problem has been aggravated by non-stop touring since June, 2012. She says she'll reschedule the cancelled concerts for sometime next year.

Giving booze to a bunch of horny kids living in the American wilderness sounds like a pretty bad idea ... unless it's for the Alaskan reality show "Slednecks" ... which struck gold when a CRAZY brawl broke out during a party scene.

Production sources tell us ... "Slednecks" (which used to be called "Buckwild") staged the party inside a barn that doubled for a rickety nightclub. There was lotsa liquor for the cast and a bunch of yocals.

Hollywood producer Jeff Dowd -- who inspired "The Dude" character in "The Big Lebowski" -- is suing UCLA's hospital for $10 million ... saying his mom died because of poor communication between doctors, TMZ has learned.

According to the lawsuit ... Dowd's elderly mother was hospitalized March 29, 2013 suffering from bronchitis ... and was dead within a month after she got progressively worse -- suffering internal bleeding, dehydration and finally a massive stroke.

Dowd tells TMZ ... his mother was handed off from one doctor to another, often without adequate information about what meds she was taking. Dowd says it was that breakdown in communication that led to her death.

Dowd -- who's also suing a convalescent home -- says he wants to help reform communications in the medical field ... saying hundreds of thousands of people die in hospitals every year from that kind of failure.

And that ... the Dude does NOT abide.

Miley Cyrus is sticking to her story ... it was an allergic reaction that put her in the hospital for a week ... saying the whole ordeal drove her "insane."

Miley called into Ryan Seacrest's radio show on Monday, where she detailed how she ended up so sick: "I was on this medicine for five days and everything was all good and on the sixth day, I just woke up … it was so scary … I had basically been poisoning myself with something I didn’t know I was really scary allergic to and it was so scary."

She cancelled several tour dates while laid up, said she was crying all the time because she was so bored and passed the time by online shopping.

"Instagram's Biggest Playboy" can add Instagram's biggest dumbass to his resume -- the guy threw a FULLY NAKED porn star off the roof of a Hollywood Hills mansion into a pool ... breaking her foot in the process ... and it was all caught on tape.

Dan Bilzerian -- a millionaire pro poker player famous for his extravagant IG photos -- was doing a shoot for Hustler magazine on Wednesday with 19-year-old Janice Griffith when he got the brilliant idea to cup Griffith's vagina ... and throw her headfirst into the pool. From the roof.

Needless to say, things didn't go as planned -- Janice later tweeted from the hospital, "I broke my foot today."

You have to see the video to see how epically stupid this is.

If only the Darwin Awards offered consolation prizes.

Robin Roberts picked up some unexpected side-effects -- good and bad -- when she got a life-saving bone marrow transplant 2 years ago ... and says it's all her sister's fault.

Robin's sis Sally-Ann donated the bone marrow to help Robin treat a rare blood disorder.

The transplant gave Robin a fresh infusion of stem cells ... but Wednesday in NYC -- she told us she also inherited some of her sister's physical traits.

Lindsay Lohan says she suffered a miscarriage during the taping of her reality show.

Lohan dropped the bombshell during the final episode of the OWN show Sunday night ... when asked to reflect on her experience with the reality show.

"No one knows this," Lohan said ... "I had a miscarriage for those two weeks that I took off.”

She continued, "It's a very long story, but that's why on the show when it says she doesn't want to come down, I couldn't move, I was sick. Mentally, that messes with you."

"Big Brother" Season 8 winner Evel Dick Donato is convinced a car SMASHED INTO HIM Friday night in Ireland ... and his injuries look really, really bad.

Dick posted a photo on Twitter last night showing his messed up face with the caption, "Pretty sure I got hit by a car, but I have no memory of what happened... at all."

The next morning, Dick began to recall what went down and said he was biking home after drinking at a bar in Dublin -- when suddenly, he was being woken up on the side of the road by a cab driver.

Dick refused medical treatment ... but the next morning promised his followers he'd get checked out.

Jodi Arias got more than a murder conviction in Arizona ... she got Hepatitis C ... and she blames it on Sheriff Joe Arpaio, who she also claims is in a conspiracy with none other than Nancy Grace.

Jodi -- who was convicted last year of murdering her ex-BF Travis Alexander, is awaiting the death penalty phase of the case.

Jodi claims in new legal docs -- obtained by TMZ -- while she was in the custody of Sheriff Joe ... she was given a Tuberculosis shot with an infected needle, which gave her Hep C.

She also claims her left silicone breast implant leaked and caused a fungal growth. Jodi alleges she was denied medical care.

Jodi also claims Joe has put cameras in her cell and forces her to say the Pledge of Allegiance every morning or else she won't get fed.

Now Nancy Grace ... Jodi alleges Joe intercepted sexual letters between her and Travis' cousin and leaked them to Nancy, who then blabbed about them on TV. Nancy claimed the 2 were getting hitched.

"The Chew" TV studio in New York City is a veritable death trap ... according to a woman who claims she was seriously injured at a taping of the show.

According to the lawsuit obtained by TMZ ... Angelina Delic says she was part of the show's studio audience in 2012 when she tripped and fell down some stairs, which did not have a handrail.

Delic's lawyer tells TMZ Delic stumbled over a raised toe strip, fell down six steps, and landed on her right shin (gnarly photo below). The lawyer says nothing was broken, but she eventually developed a bacterial infection. The lawyer says Delic had to see her doctor on 21 occasions to treat the infection.

And credit to Delic's lawyer for painting a harrowing picture of the studio in the lawsuit ... calling it "dangerous, full of debris, hazardous, unsafe, full of traps and concealed dangers."

She's now suing ABC for negligence. Delic doesn't name an amount, but her lawyer says the medical bills alone exceed $50K.

A rep for ABC tells us they have no knowledge of the claim.

Wu-Tang affiliated rapper Andre Johnson is just plain Andre now ... because doctors weren't able to reattach his penis.

TMZ broke the story Johnson -- aka Christ Bearer -- cut his penis off Wednesday morning and then jumped off his 2nd floor North Hollywood apartment balcony. He was rushed to Cedars-Sinai Medical Center but we're told the penis was a lost cause.

Johnson/Christ Bearer is a member of the group Northstar, which was founded by Wu-Tang Clan member RZA. We're told RZA hasn't done work with the group for several years.

Johnson/Christ Bearer is remarkably in stable condition.

As we reported ... several rappers were present during the horrific scene. They say they were not doing any drugs that would cause such a thing. They believe Johnson/Christ Bearer may have mental issues.

Miley Cyrus' hospitalization was triggered by a sinus infection gone horribly wrong, TMZ has learned.

Reps for Miley tell us, the singer got an Rx for an antibiotic called cephalexin (brand name Keflex) to treat a sinus infection after getting diagnosed last week in North Carolina.

We're told within days Miley's throat swelled to the point she could barely talk. She was rushed to the hospital Tuesday night and, according to her rep, doctors determined she had an extreme allergic reaction to the drug.

We're told Miley never got a cephalexin script before so she had no idea she was allergic.

She'll remain hospitalized until her condition improves. Her doctor says an allergic reaction of this kind can last 27 days.

A rapper affiliated with Wu-Tang Clan was rushed to the hospital early Wednesday after he cut off his penis and then jumped off a second story balcony in what police believe was a suicide attempt ... law enforcement sources tell TMZ.

Our sources say ... cops were called to an apartment building in North Hollywood at around 1:00 AM and found Christ Bearer -- aka Andre Johnson -- on the sidewalk critically injured.

Christ Bearer is a member of the rap group Northstar ... a group discovered by members of Wu-Tang Clan. Two members of a group Bearer collaborates with live in the same apartment building and tell TMZ they were there early this morning when Christ Bearer suddenly -- without warning -- cut off his penis and jumped off the balcony. They say they were not on "any hard drugs that would cause him to do such a thing."

The two men say they rushed downstairs and Christ Bearer had already jumped up and began screaming incoherently.

Johnson was rushed by ambulance to Cedars-Sinai Medical Center. It's unclear if doctor's are attempting to reattach Johnson's penis.

Johnson is a rapper who was in a group founded by members of Wu-Tang Clan.

Kris Jenner has a medical problem that required her to go to the hospital, and even though they're separated when times get tough her go-to person is still Bruce.

We've learned Kris just went to a hospital in Thousand Oaks -- near her home -- for X-rays and possible tests for an undisclosed medical problem. She was accompanied by Bruce, who we believe came from his home in Malibu to be with her.

Kris and Bruce have actually become closer we're told since their separation, because there's no tension over the relationship anymore -- they're simply close friends and confidantes.

Again ... it's unclear why Kris needed to go the hospital.
