Story developing ...

Kim and Kyle Richards are being sued by a stylist who claims Kim's pit bull viciously attacked her and Kim refused to call 911 unless the woman lied to protect the dog.

Paige Sanderson says in a new lawsuit -- obtained by TMZ -- she went to Kyle's house in April to help Kim dress for a promotional appearance for 'Real Housewives of Beverly Hills.'

Sanderson says when she saw Kim's pit bull, Kingsley, she became fearful and ran into a bathroom. She says she was assured the dog was docile, so she came out and says Kingsley went ham.

Sanderson says the dog lunged at her, bit and held on to her lower abdomen and crotch, tearing off her leggings and underwear and ripping out portions of flesh.

From there she says it only got worse. According to the lawsuit, Kim refused to call 911 unless Sanderson lied to EMT's by blaming the attack on a stray dog ... not Kingsley.

Kingsley has a history of attacking. The dog bit Kyle's daughter, Alexia, in November 2014, sending her to the hospital. The dog also attacked a dog trainer and an 80-year-old woman.

The stuntman Tom Sizemore ran over should make a full recovery ... we've learned his injuries were not as massive as first thought.

A rep for the actor tells TMZ the "Shooter" stuntman suffered 2 broken ribs and a wrist ... requiring surgery. A production source backs up the medical assessment.

TMZ broke the story ... Sizemore was behind the wheel when he hit the gas on a Cadillac SUV, running over and pinning the stuntman. He was airlifted to a local hospital.

Production sources say Tom was only supposed to jump in the vehicle ... not drive it. Tom says that's not true ... the scene called for him to drive away.

2:55 PM PT -- Sizemore's rep tells TMZ the stunt coordinator prompted him to "pull out" once he got in the SUV. He says 3 cars pulled out at once. Tom, who was driving the SUV with Omar Epps, says he followed instructions, drove off and never saw the stuntman before hearing a "thump."

A stuntman in a new TV show was badly hurt Wednesday after being struck by and pinned under an SUV, which we're told was being driven by Tom Sizemore ... TMZ has learned.

"Shooter" was being filmed at Agua Dulce Airport ... near Los Angeles, where they were filming a sniper scene. We're told Tom was supposed to run into the Cadillac SUV and just sit there until the scene ended, but he put the vehicle in reverse, hit the gas, and ran over the stuntman.

Eyewitnesses tell TMZ ... 8 guys on the set tried in vain to lift the car off the stuntman. Someone finally brought in some equipment and they were able to jack the car up and free the man.

According to one first responder, the stuntman "is in real bad shape." He was airlifted to a nearby hospital. His condition is unknown.

The show stars Ryan Phillippe, Omar Epps and Sizemore.

Chelsea Manning's attorney is accusing the Army of outright lying to cover up what appears to be a suicide attempt behind bars.

Attorney Nancy Hollander tells TMZ she and her team had been cleared to have a routine call with Chelsea Tuesday afternoon, but when they called in they were told there were problems connecting the call. The staff at Leavenworth made no mention of a suicide attempt.

Hollander says she's been trying in vain to get in touch after we posted a story that Chelsea apparently tried hanging herself in her cell early Tuesday morning.

Now Hollander says she's been informed she cannot even talk to Chelsea until Friday at the earliest.

Chelsea Manning, who's serving a 35-year sentence for leaking classified military documents, was in a prison hospital and our sources say it was the result of a suicide attempt.

We're told the incident occurred early Tuesday at Fort Leavenworth, Kansas prison. We do not know specifically what Manning did in her cell, but one source tells TMZ she tried to hang herself.

Prison officials tell TMZ although she has been released from the hospital she is being "monitored."

Manning was convicted on 20 counts of espionage, for passing classified docs to WikiLeaks.

Manning transitioned from male to female behind bars.

Paris Jackson apparently saw our story Monday -- that she's cut off all contact with her mom, Debbie Rowe, who's now battling breast cancer -- because we've learned Paris just contacted Debbie and proclaimed her love ... this according to Jackson family sources.

As we reported, Paris broke off contact with Debbie more than a year ago. We're told Paris' family was upset MJ's daughter had reconnected with Debbie after the singer's death and became close. On top of that, when Paris began acting out Debbie became the disciplinarian ... something Paris didn't like.

Debbie was diagnosed with breast cancer recently and will undergo surgery. We're told Paris texted Debbie, "I love you," and it appears the 2 will meet up after the surgery.

Michael Jackson's ex-wife has breast cancer, and their estranged daughter doesn't even know.

We've learned Debbie Rowe was diagnosed recently and will undergo surgery in the next week, but her daughter, 18-year-old Paris Jackson, has no idea because she broke all contact with her mom more than a year ago.

Rowe has all but given up on salvaging the relationship. After Michael died, Debbie and Paris got extremely close, to the point it created friction with the rest of the family.

When Paris began dealing with her own problems, the relationship fell apart. Rowe believes the family influenced their daughter and drove a wedge.

Lindsay Lohan will have to celebrate her 30th birthday without Dina Lohan ... who's holed up in a hospital and doctors have no idea what's wrong with her.

Sources close to Dina tell us she was taken to the hospital last Friday after complaining about severe stomach pains. We know what you're thinking -- it wasn't gas.

Doctors couldn't diagnose that initial pain, and we're told now Dina's aches have moved to her back and neck ... and it's getting worse. She's had several MRIs and CAT scans, but doctors are still baffled and Dina's spent the last 6 nights in the hospital.

The family sent us a pic, and while she seems to be in decent spirits ... we're told Dina's upset about missing LiLo's bday party in Greece.

Docs are managing her pain with meds.

Good news, America -- one of the best basketball players in the country says she's NOT SCARED of Zika -- and will absolutely travel to Rio to lock up that gold medal at the 2016 Olympics.

We spoke with WNBA superstar Angel McCoughtry -- 4-time All-Star, 2-time scoring champ -- who tells us she believes the Zika situation is being blown WAY out of proportion.

"There's always something that comes out every year," Angel said.

"Last year it was Ebola. Before that it was swine flu. It was something before that ... guess what 00 we ain't worried about that Zika Virus!"

A DJ claims Walgreens sold him defective earplugs and the results were catastrophic.

Joseph Alpern says in a new lawsuit he bought the plugs in 2013 because he was about to start working at a Brooklyn club known for its powerful sound system.

Alpern claims he used the plugs for several hours and when he left the club he removed them, only to experience "an immediate sharp pain, accompanied by a ringing sound."

He says the pain didn't go away, and 6 months later he realized the damage wasn't going away either ... he had constant ringing in both ears and couldn't sleep on his right side.

Alpern went to a specialist, who gave him bad news ... he had permanent nerve damage and blames it on the plugs. The doc said the plugs were sealed so tightly, when he pulled them out it severely pulled his eardrum.

Alpern says now he suffers headaches, he's constantly fatigued and can't even listen to music at regular volumes.

He's gunning for $640,000 ... minimum.

Drake's muscle packs a mean punch ... according to the guy on the receiving end.

We got these pics of the injuries of producer/rapper Detail, who claims the bruises were inflicted at the hands of Drake's security guard.

We're told the injuries were so bad he was hospitalized for days ... with a broken jaw and other injuries that required several surgeries.

As we reported, Detail claims Drake invited him to his home back in 2014 on the pretext of working on a project, but it was really an ambush. Detail says Drake was pissed he wouldn't work exclusively with the Canadian rapper.

Detail says he was so badly hurt he couldn't work for a year, and he asked Drake repeatedly, and in vain, to cover his medical expenses. When Drake refused, Detail had lawyers, Panish Shea & Boyle, file a lawsuit.

Biebs went down hard during a pick-up game Friday in Cincinnati ... and came out of it with a severely swollen ankle.

They can all suck air again. Justin says he's going to have to take it easy onstage, but promises he's "still gonna crush."

A Tony Robbins' motivational seminar went haywire in Dallas when more than 30 people who walked on hot coals had to get treated for burns.

According to reports ... 5 people were hospitalized Thursday night, while the rest were treated on-site for burns to their feet and lower legs. Tony had encouraged attendees to walk the coals in order to conquer their fears. It's a common thing at Robbins' events.

Tony's people tell TMZ ... 7,000 guests walked across the coals and only five "requested any examination beyond what was readily available on site."

At least one attendee blamed the burns on a lack of focus -- some people were reportedly taking selfies. This also happened at a 2012 event in San Jose.
