Nurse!

The guy Baywatch star Jeremy Jackson knifed over an alleged robbery is pissed ... telling TMZ he was only trying to help out the actor ... and ended up getting stabbed 9 times for it.

The first part of his story syncs up with Jeremy's -- he was called to help Jackson recover some stolen cash ... which he did. After that Jeremy and the guy -- who doesn't want his name out -- didn't really see eye to eye.

He accuses Jeremy of stealing from him, but Jeremy claims it was the other way around.

Bottom line, he says Jeremy knifed him over and over -- to the arms and torso -- and he needed 177 stitches and 3 pints of blood.

Taylor Swift is so popular in Japan she got in the way of commerce ... apparently flights were delayed after the airport was overrun with fans.

Taylor landed in Narita Airport to kick off her "1989 World Tour," when a predicable number of fans showed up and went crazy.

We've seen people at Narita Airport fan out before, but apparently this one was too much. People on scene say at least 2 arrivals were delayed because of airport congestion ... the result of Taylor's immense popularity.

LeAnn Rimes is lucky she's famous ... because most people would be in serious trouble if they set off the fire alarm on an airplane, but she was able to joke about it.

The country music/reality TV star was on a flight to Los Angeles, when she took a bathroom break to freshen up. As she explains it: "Leave it up to me to set off the fire alarm in the airplane bathroom w/ @theDrybar dry shampoo #purecomedy #firsttimeforeverything."

Our photog was waiting for LeAnn when she landed, and she laughed off the whole thing -- although it sounds like the flight staff wasn't as amused ... at first, anyway.

Seems like it was only yesterday Amal Clooney's hot kid sister Tala Alamuddin stepped into the spotlight, and now she's already tripping in it.

Tala got a closer look at the pavement outside Il Buco Thursday night in Manhattan where she was celebrating her birthday with Amal and George Clooney.

Like a pro, she knows knees can heel and never drops her Alexander McQueen clutch.

Blues legend B.B. King's daughter believes he is being abused ... and called police Thursday to settle a dispute over whether he needed to be hospitalized.

TMZ has learned there's a huge battle over B.B.'s care -- between his daughter Patty King and his longtime manager Laverne Toney. Patty, who lives with her father in Las Vegas ... tells us she wanted to take him to the hospital because his urine was orange and he wasn't eating.

She claims Toney -- who has power of attorney over B.B. -- refused, so Patty called police. Responding officers called in paramedics, who agreed B.B. needed to be checked out by doctors.

89-year-old King was treated at the hospital -- and Patty says he suffered a minor heart attack. She also says this photo was taken during his brief stay, and she hopes the image will convince authorities something needs to be done to protect him.

Patty and her boyfriend filed a police report last November ... claiming elder abuse, and burglary. They accused Toney and her assistant of fleecing $20-$30 million from B.B., withholding his medications while on tour -- and jacking several Rolexes and a ring valued at $250k.

Police are investigating, but no charges have been filed yet.

We've reached out to Toney for comment, but so far no word back. Patty says she's meeting with her attorney to discuss wrestling power of attorney away from Toney.

Barbra Streisand's female dog just got herself into serious trouble at 36,000 feet -- attacking a flight attendant aboard a billionaire's fancy private jet ... and it was so bad, the victim needed stitches.

The perp is a bitch named Sammie -- Barbra's 12-year-old Coton de Tulear ... who accompanied Streisand on Tuesday during a flight from NYC to DC on a PJ owned by billionaire investor Ron Perelman.

Our sources tell us ... a female flight attendant noticed the dog and went over to pet her, but Sammie snapped, biting the woman's hand ... puncturing the skin and opening a wound that required stitches.

We're told Barbra IMMEDIATELY apologized to both Ron and the flight attendant -- but everyone forgave her and the injured woman is expected to make a full recovery.

Britney Spears hurt her ankle so badly during her Las Vegas show Wednesday night, she's been forced to cancel two shows.

Her shows for this coming Friday and Saturday will be rescheduled after doctors advised her not to perform ... opting instead to rest her injured ankle so it can heal.

So, now it looks like Britney has no plans on Saturday night ... or she will be front and center at the Floyd Mayweather/Manny Pacquiao fight, which just happens to be the same night ...

See ya there, y'all!!!

"Love & Hip-Hop: Atlanta" star Momma Dee was rushed to the hospital after a scary car accident in Atlanta involving her Uber car service.

MD tells TMZ she was in the back of an Uber on her way home from lunch Thursday afternoon ... when a man in a Nissan struck her ride from behind. Dee says she is in severe pain and believes she's injured her back. An ambulance is taking her to a hospital right now.

Dee says the driver of the Nissan pulled over to exchange his information with her driver, but left the scene before police showed up.

Law enforcement sources confirm one person is being transferred from the accident scene -- and they say the victim made it clear ... she's a celebrity.

Britney Spears went down hard during her Las Vegas show -- falling so hard mid-song ... it was up in the air whether she'd stay down or go on with the show.

She did both -- staying down, and dancing from her backside.

Brit Brit rolled her left ankle pretty good, but managed to keep going through the end of "Crazy."

Her dancers eventually helped her to her feet, and she seemed to walk it off. The fall looks nasty, but Britney assured fans later ... she's ready to get back in the game.

Good news for Kareem Abdul-Jabbar ... the NBA legend has been discharged from the hospital and is now resting at home after a scary medical emergency early Wednesday morning.

TMZ Sports broke the story ... Kareem was rushed to the hospital and was being treated after something went wrong in his recovery from quadruple bypass surgery earlier this month.

Now, a rep for Ronald Reagan UCLA Medical Center is explaining exactly what happened:

"[Thursday morning] Kareem Abdul-Jabbar was experiencing some dizziness following his April 16 quadruple bypass surgery. He contacted his physicians who told him to come to the emergency department at Ronald Reagan UCLA Medical Center."

"He was evaluated by his surgeon and cardiologist. After a battery of tests, they found no complications. Abdul-Jabbar was discharged from the emergency department and is back home continuing his recovery."

"His surgeon, Dr. Richard Shemin, said it is not uncommon for patients to experience some symptoms that require ruling out serious problems following major heart surgery. Shemin added that Abdul-Jabbar did the right thing by coming in to see his doctors."

Kareem Abdul-Jabbar was rushed to an L.A. hospital Wednesday morning for chest pains ... just two hours after he tweeted to fans that he was "feeling better" ... TMZ Sports has learned.

We've confirmed ... someone called 911 to request help for the NBA legend ... who had a quadruple coronary bypass surgery on April 16th.

An ambulance transported Abdul-Jabbar to a nearby hospital where he was treated for chest pains. He's currently being treated by doctors though his condition is unclear.

Just two hours before the 911 call, Abdul-Jabbar posted a message on Twitter to assure his fans that he's "doing fine & feeling better everyday."

He added, "Doing my rehab w/the same mental commitment I had as a pro."

Joni Mitchell is unconscious in a hospital, unable to respond to anyone, with no immediate prospects for getting better.

Joni's close friend of 44 years, Leslie Morris, has just filed legal docs to obtain a conservatorship over the legendary singer. Morris says Joni told her she has no close relatives who could assume the role.

TMZ broke the story, Joni was rushed to the hospital on March 31st, after being found unconscious at her L.A. home. She was taken to UCLA Medical Center, where she remains.

Joni, whose hits include "Big Yellow Taxi," is not responsive to anything. The documents say she's "so impaired as to be incapable of being assessed."

Big Ang is out and about and flaunting new blonde locks ... just a few weeks after undergoing a lifesaving operation to remove a cancerous tumor from her neck.

The "Mob Wives" star was looking good Saturday outside Teak restaurant in Red Bank, NJ, and even stopped to pose with a fan. We're guessing the neckerchief is there to cover any surgery scars -- in the most stylish way possible.

Sources close to Ang tell us she lightened up before the surgery ... because she felt like she just needed a change after getting the cancer diagnosis.

Work it, Ang.

Brad Pitt's face is indestructible -- a fact whoever (or whatever) hit Brad should have known before attempting to disfigure our national treasure.

Brad showed up for a charity event in Hollywood Saturday night with a big bruise that starts under his left eye, and trails under his nose.

Most people would've stayed home with that kind of scarring, but most people don't have BP's genes. No clue what's behind this crime against beauty -- we've got a call in to his rep.

Lil Wayne's tour bus took on gunfire in Atlanta early Sunday morning ... TMZ has learned.

Wayne performed at Compound nightclub on Saturday night ... and sources tell us the shooting went down shortly after 3:30 AM -- minutes after Wayne's 2 tour buses pulled away from the club.

We're told Weezy and a few other Young Money execs and artists -- including Lil Twist and Hood -- were on board at least one of the buses at the time of the shooting. It appears no one was injured, and it's still unclear if Wayne was on board the bus that was hit.

Law enforcement sources tell us immediately after the shooting the bus was driven to a nearby hotel, and that's when someone in Wayne's entourage called cops.

We're told witnesses on the buses didn't see much -- their only description of the suspects is that they were in 2 white vehicles ... a sports car (possibly a Corvette) and an SUV.

"Night Court" star John Larroquette was involved in a brutal car accident that severely injured a reality TV star, who claims he can't get no satisfaction ... from John or his insurance company.

The alleged victim is Joe Meinwieser -- a tattoo artist on Oxygen's "Tattoos After Dark" -- and his list of injuries are horrific: broken ribs, fractured spine, fractured hand, and loss of half his kidney.

Meinwieser claims Larroquette made an illegal turn out of a Venice, CA parking lot in December -- smashing into him and his motorcycle.

Police investigated, and law enforcement sources tell us it's unlikely JL will face criminal charges.

That's not sitting well with Joe -- who claims Larroquette promised to cover his medical expenses ... but the actor's insurance company won't pay up. He says he can't work, and his unpaid medical bills are mounting.
