Salt-N-Pepa's 90s Fest appearance was a serious hit for Pepa ... who took a NASTY fall while trying to bust out some daredevil moves on a wet stage.

The rap duo was performing Saturday night in Brooklyn, and while "Sweet Child O' Mine" was blaring ... Pep tried jumping between speakers at the front edge of the stage.

She did NOT make it very far.

Chris Cornell took a turn as a stuntman on his latest music video and it ended with the rocker suffering severe burns.

It went down while Cornell was shooting the video for "Nearly Forgot My Broken Heart." Production sources tell us the Soundgarden frontman insisted on doing his own stunts in the "Deadwood"-like video.

The big stunt ... a liquid chemical singeing a noose tied around his neck in a mock hanging (check 2:50 in the video).

It didn't go as planned and they were forced to do it several times ... with the chemicals eventually rubbing off on his neck and leaving the crooner with 2nd degree burns.

Don't worry groupies ... it didn't affect his gorgeous chiseled face.

Ex-Laker Ronny Turiaf says the death of Moses Malone at only 60-years-old ... hit very close to home for him ... since he too has dealt with life-threatening heart issues.

Turiaf was in L.A. Sunday night, and he opened up about Malone's legendary game -- and said it immediately reminded him about his 2005 open heart surgery. Seems Ronny assumed Malone had gone by heart attack, since he wasn't that old.

Turns out he was right. We broke the story ... the Medical Examiner says Malone died from heart disease.

On a lighter note -- former NBA star John Salley reminisced about ballin' against the "Chairman of the Boards."

NBA great Moses Malone died due to a severe hardening of his arteries ... TMZ Sports has learned.

"​The Bachelorette" star JJ Lane got bit so badly during a hockey game he almost lost his finger.

JJ was on the ice Tuesday in Denver. He checked a guy, pinning him against the boards, when the opposing player went loco, chomping down on JJ's pinky.

One of JJ's teammates sprung into action, bashing the aggressor on the back with his hockey stick until the guy released JJ's digit.

JJ went to the ER where doctors cleaned out the bloody mess and splinted it up.

JJ's had a spate of bad luck lately ... he was hospitalized back in July after allegedly being jumped by gang members.

Someone snuck a picture during the autopsy of Vester Flanagan, the man who shot and killed a Virginia reporter and cameraman, and it's being shopped around to the media.

We were contacted by someone who sent the pic, taken on an autopsy table. We passed, but whoever called seems determined to make a quick buck.

The photo is pretty gruesome ... taken mid-autopsy with a slit open chest. It looks like the person who took the pic lifted the sheet for a better view.

Justin Bieber is pulling the "what do you mean?" card on a New Jersey woman who's suing him after she tripped on a loose cable at one of his concerts.

Bieber's camp is calling BS, saying there were NO electrical cables lying anywhere around where Sandy Ricketts was standing, during the 2013 "Believe Tour in Philly". They say if she hurt herself she has her own clumsiness to blame.

In Bieber's legal docs, there's also an interesting reference to the fine print on the concert tickets, which say fans assume the risk of injuries when they attend.

Ricketts says she was hurt bad ... severe and permanent injuries including a broken shoulder, busted lip that required surgery and a sprained wrist.

Rachel Uchitel will undergo surgery so major, her entire brain will be lifted off the cavity.

We're told Rachel has been suffering from back pain for years, but all treatment failed. She recently went to a surgeon who told her she had a condition called Chiari, a birth defect that causes brain tissue to settle into the spinal canal.

Tiger Woods' former GF will go in for surgery in 2 weeks, where doctors will cut a hole in the back of her head and lift the brain off the spinal canal.

Rachel's terrified but doctors say they're fairly confident ... 50% become symptom-free, 10-30% improve significantly and the rest don't.

4:15 P.M. PST -- In a statement to People, Alba claimed the lawsuit was, "baseless and without merit." She says, "We strongly stand behind our products and the responsibility we have to our consumers.

Jessica Alba's billion dollar The Honest Company is under fire after one angry customer says the company isn't too honest when labeling its products as "natural" ... according to a lawsuit.

The class action suit -- filed by Jonathan Rubin targets the brand's dish soap, hand soaps, surface cleaner and diapers. Rubin claims all of the products contain synthetic preservatives and should not be considered "natural" like THC claims.

Rubin backs up his claims with studies from an environmental group who says the ingredients were considered to be potentially hazardous.

And as one final burn ... Rubin says THC's sunscreen is ineffective after multiple users posted on blogs saying they became sunburned and blistered.

He's asking for all profits generated from those products to be refunded to people who have purchased them -- a minimum of $5 million.

Tori Spelling wants to torch Benihana in court after getting burned so badly in one of the restaurants, she was hospitalized ... according to a new lawsuit.

Spelling says she was at a Benihana in Encino, CA in April when she slipped and fell ... receiving, "deep second and third degree burn injuries." She reportedly fell onto one of the hibachi grills.

In the lawsuit Spelling says she racked up medical expenses, "general damage" and wage loss ... although there's no mention of where she was employed. She's suing the Benihana corporation -- not just the Encino location.

Tori's alleged injuries were still obvious in these pics from July.

Kris Jenner just schooled us and anyone else who thought her "fat lip" excuse for cancelling a TV appearance was fake ... she says it was real, and serious.

We got this pic of Kris taken Monday morning, around the time she called producers of "Bachelor In Paradise: After Paradise" and cancelled her scheduled appearance, saying her lip blew up and she was not camera ready.

Kris says the culprit was most likely a spider so she had her room sprayed by an exterminator. The swelling was serious enough for a doctor to prescribe 4 different meds.

As for showing up Tuesday night at Nobu and looking just fine, Kris made it clear to friends and family it took 18 hours for the swelling to go down.

It's not the first time Kris' lips blew up ... she had an allergic reaction to food in the Dominican Republic a few years back.

Janice Dickinson fell unconscious, live on TV ... after she got stung by a bee in the "Celebrity Big Brother UK" house -- and TMZ has learned it was touch and go whether she'd survive.

Janice was sitting in the Diary Room during Tuesday's broadcast ... begging producers to bring an EpiPen after she suffered the sting. She showed staffers just how bad it was -- one of her hands was almost purple, she was having trouble breathing, and panicked, "I don't want it to reach my heart!"

Then Janice appeared to have a seizure before collapsing and falling off the chair. Producers briefly cut away, but then returned to the drama. Some viewers were outraged the medical emergency aired live.

According to a 'Celeb BB' rep ... Janice was taken to a hospital for a few hours for treatment, and then returned to the house.

Sources who were in contact with Janice during her hospital visit tell TMZ ... it was very serious and Janice "almost died." We're told she's extremely allergic, but didn't have her own EpiPen with her in the house.

The fact that she's back in the house would lead you to believe Janice is okay, but show reps aren't saying anything more about her condition.

Brian Austin Green will almost certainly get spousal support from Megan Fox in their divorce, and the reason appears to stem from a terrible car accident.

TMZ broke the story, Megan filed for divorce Friday. As we said, our sources say it's likely she'll end up paying Brian spousal support, because of the large disparity in income and income potential.

We're told Brian has worked very little since last December, when he was in a head-on collision. As we reported, Brian and Megan were driving when they were hit by a drunk driver who was arrested. Brian says the guy was going around 50 MPH and it was severe enough for the airbags to deploy.

At the time of the accident TMZ was told Brian and Megan were not injured. But now we're told the accident triggered a serious medical condition ... vertigo, which affects balance.

Our sources say Brian's vertigo is so bad he can't get out of bed. We're told he hasn't worked since the accident.

As we reported, Brian and Megan -- who is working steadily on huge movies -- are still living in the same home.
