Kanye West was rushed to the hospital with a throbbing headache while on tour down under ... but made a quick turnaround and was able to perform the same night.

Yeezus and his entourage rushed to the emergency room Wednesday in Melbourne after playing basketball.

Sources tell us Kanye had a pretty intense migraine. He was released later that afternoon after doctors checked him out and determined it wasn't serious.

The Australian media is claiming Kanye suffered seizure like symptoms ... but we're told it's not true.

12:50 PM PT -- According to local police, O'Haire committed suicide. He was found in his bedroom beside his bed, with a red rope tied around his neck and connected to the bedpost. His body was discovered by his father, who then called 911.

Former WCW and WWE wrestler Sean O'Haire was found dead Tuesday at his home in South Carolina ... TMZ has learned.

The coroner in Spartanburg, SC tells TMZ a cause of death is unknown at this time, but no foul play is suspected. They are awaiting toxicology reports that might shed light on things.

O'Haire (whose real name was just Sean Haire) made his debut with the WCW in 2000 and along with partner Chuck Palumbo, was the final WCW tag team champions when the organization folded.

Once in the WWE, he was Rowdy Roddy Piper's protege, but when Piper left in 2003 ... O'Haire fizzled out and eventually left the WWE in 2004.

He eventually transitioned into kickboxing and MMA before becoming a hair stylist.

Taylor Swift believes Katy Perry is a thief ... and we've learned that's the basis of their feud.

The girl-on-girl war ignited when 3 of Taylor's dancers jumped ship and joined Katy's tour. Taylor felt betrayed because she became very close to the dancers and considered them family.

But here's the thing. The 3 dancers had actually worked with Katy first, but when Katy's tour ended several years ago they needed work. So they signed up as dancers during Taylor's tour.

We're told the dancers told Taylor up front ... they did not want to sign for the full tour -- they wanted a 30-day out, and we're told it's because they were just waiting for Katy to go back on tour.

When Katy hit the stage again, they gave their 30-day notice, but Taylor got so pissed off she fired them on the spot.

All of this went down a year ago but we're told Taylor held a grudge, which boiled over when she wrote a song -- "Bad Blood" -- alluding to Katy screwing her over.

It's turned into a full on war, with Taylor not-so-coyly talking about the alleged betrayal -- and Katy responding on Twitter by calling Swift ... Regina George in sheep's clothing.

Momma Dee's a true multi-tasker ... busting out both a song and her tooth at the same time.

The "Love & Hip Hop: Atlanta" star has a "flipper tooth" -- a removable fake tooth -- which made a hasty exit smack in the middle of her single release party at Club Sutra in ATL.

Momma didn't let a floppy incisor get in the way of her big night. She struggles for a sec, but eventually pulls it together.

Several Baltimore Ravens players are saying ... they will not treat Ray Rice like an outcast -- and have vowed to support him as a friend ... team sources tell TMZ Sports.

Our sources tell us ... multiple players have already reached out to Ray to let him know they won't turn their backs on him in the wake of new elevator video showing the running back attacking his then-fiancee.

We're told Ray has apologized to some of his teammates for his actions and has said that he is actively seeking counseling and going to church in an effort to move on with his life.

The FBI descended on the Four Seasons Hotel in Bev Hills ... on the hunt for a woman they believed was making death threats and harassing phone calls to Kris Jenner and her family.

FBI sources confirm ... agents obtained a search warrant targeting a suspect -- a black female who drives a 2004 silver Toyota Corolla -- the woman they believe is behind the threats.

The agents seized a cell phone, laptop, iPad and iPod Touch when they rooted through the woman's hotel room Friday ... but she was not arrested.

TMZ broke several stories in the past ... about a woman who was incessantly calling Kris Jenner and making various threats. She sometimes called as many as 300 times a day, threatening to release a sex tape starring Kris and Bruce Jenner. She wanted money in exchange for the phantom tape.

Sarah Jessica Parker and Matthew Broderick are trying to unload their massive Greenwich Village townhouse and they are enlisting the services of a Bravo reality star to help them score a massive pay day.

Parker and Broderick are listing the multi-million dollar home with Fredrik Eklund, who stars on the Bravo series, "Million Dollar Listing New York."

The townhouse is 6,800 square feet with 7 fireplaces, and is so massive ... it has a "guest floor" with three bedrooms!

The couple bought the place in 2011 for $18.995 million and is asking $22 million for it now.

Siva Kaneswaran fought off a man he says was beating a woman on the street in NYC -- and ended up catching a shiner in the process.

"The Wanted" singer was walking in Chelsea last month with his rep ... when they saw the man attacking his girlfriend. The rep tells us Siva ran over and tried to break it up, telling the man to chill out -- but the attacker yelled back, "This isn't about you."

The rep says that's when it got physical -- while Siva was trying to hold the guy back, he got clocked in the face. The attacker eventually took off, but the scuffle gave the GF enough time to run away.

We're told Siva initially wanted to keep the fight -- and his shiner -- under wraps, but is now hoping the woman will get in touch with him so he can be sure she's okay.

Siva's got a bad record with good deeds. A homeless man attacked him outside a Denver movie theater earlier this year ... when he tried to give him money.

Joan Rivers -- who made the world laugh for over 50 years with her jokes, put-downs and one-liners -- has died in NYC ... a week after her heart suddenly stopped beating during vocal cord surgery.

She was 81.

Joan's daughter Melissa Rivers took her mom off life support so she could pass comfortably in a private room.

The death has been reported to the NYC Medical Examiner's Office -- and officials tell TMZ the office will open an investigation to determine cause of death.

Melissa just issued a statement saying, "It is with great sadness that I announce the death of my mother, Joan Rivers."

"She passed peacefully at 1:17 PM surrounded by family and close friends. My son and I would like to thank the doctors, nurses and staff of Mount Sinai hospital for the amazing care they provided for my mother."

"Cooper and I have found ourselves humbled by the outpouring of love, support and prayers we have received from around the world. They have been heard and appreciated."

"My mother's greatest joy in life was to make people laugh. Although that is difficult to do right now, I know her final wish would be that we return to laughing soon."

Rivers is widely credited for opening doors for countless female comediennes. She broke through in a big way during her appearances on "The Tonight Show" with Johnny Carson.

She also famously enraged Carson by accepting a gig to host a competing late night show on FOX. Carson never spoke to her again.

Rivers was born in 1933 -- she worked as a writer and fashion consultant before entering show biz as a stand-up comic in the early '60s. She was famously self-deprecating ... often self-critical of her looks and her marriage to Edgar Rosenberg ... who committed suicide in 1987.

Joan's late '80s FOX show tanked, which somewhat derailed her career. It was resurrected in a big way in 2010 in the wake of the documentary "Joan Rivers: A Piece of Work."

She was universally adored by fellow comedians, including fellow legend Don Rickles, who once said about her ... "Joan is not only a very intelligent lady, but extremely masterful at comedy timing. Sharing the stage with her has always been a joy for me."

Barbara Walters was asked about Joan last year, saying ... "I wouldn't dare to try to be funny about Joan Rivers because she is the smartest, best-informed and funniest woman I know."

Joan and her daughter Melissa began working as a team hosting various red carpet and fashion shows on E! and other networks, including "Fashion Police."

Joan's credits could fill a book ... including appearances in "The Muppets Take Manhattan," "The Carol Burnett Show," "Hollywood Squares," "Pee Wee's Playhouse," "Celebrity Apprentice," "Saturday Night Live" ... and on and on.

"Versace" rappers Migos got into an all-out battle royale at one of their shows ... where all 3 members of the group ended up going loco on their fans.

The melee started Sunday night at LimeLight nightclub in Nashville -- when according to sources ... one member of the group had a gold chain snatched from his neck while on stage, and immediately went after it in the crowd.

It's pretty wild fight video -- bodies pile up on the floor as the whole thing plays out.

Police were called, but LimeLight security was eventually able to contain things and no arrests were made.

Of course, this isn't the first time the Migos have been involved in an attack on tour ... having nearly escaped death following a drive-by shooting in Miami earlier this year.

Migos definitely love a good "Fight Night."

Future and Ciara didn't stay apart for long ... and it's all because Ciara feels strongly about her son needing his father around 24/7.

Sources close to Future tell TMZ ... he and Ciara are living together again -- and trying to make things work between them -- so Future can help take care of their 4-month-old son, Future Zahir.

Ciara must be willing to overlook the past ... since she was the one who claimed Future cheated on her while he was on tour -- and then broke off their engagement last month.

We're told Ciara wasn't interested in a shared parenting situation ... saying she believes Future's a good father and that it's best for their son if his dad's there.

Pretty selfless of her, if she really believes he cheated.

The "Michael Sam to Dallas" move was a bang-bang play -- with the whole deal unfolding in just a couple of hours ... starting with a phone call from Dallas to Sam's camp around 11AM Tuesday.

Our NFL sources tell TMZ Sports ... the whole thing was like a whirlwind -- and Sam had no idea he was in the cards for Dallas until the phone rang.

After that, Sam hopped on the first plane to Texas -- where he'll join the practice squad ... pending a physical.

Reggie Bush's swag just hit Jay Z levels -- 'cause the NFL star just got himself a brand new $200,000 timepiece from the rap mogul's favorite watch company ... TMZ Sports has learned.

The Detroit Lions running back was flashing a Tourbillon Councept GMT Royal Oak by Audemars Piguet ... which often retail between $200k and $250k.

We spoke with a watch expert who told us Bush's new piece of man jewelry is "one of the finest watches out there ... it's a really special thing."

As for Jay Z, he's been shouting out the watch in rap songs for years ... and had a deal with the company for his own custom line back in 2005. Plus, he wears Audemars Piguets all the time.

Justin Bieber got arrested in Canada after crashing his ATV into a minivan driven by paparazzi ... TMZ has learned -- and he now faces charges of dangerous driving and assault.

Bieber was taken into custody Friday afternoon in Perth County, Ontario. Police say there was a physical altercation between Justin and a paparazzo in the minivan ... after they had the collision.

Justin was photographed riding the ATV with Selena Gomez Friday in Ontario near his father's home.

Police say Justin was released and will have to appear in court later this month.

He could have a bigger problem on his hands though -- Justin is on probation for 2 years after the egging case in L.A. So, it's possible this arrest could trigger a violation.

Justin's attorney says Justin and Selena are fully cooperating with the police investigation.

Talk about stamina ... boxing champ Peter "Kid Chocolate" Quillin tells TMZ Sports his wife is the REAL bad ass in the house after giving birth to their son after a 36 hour labor!!

Peter -- the reigning WBO middleweight champ -- says his son Joaquin was born last Saturday ... 8 pounds, 2 ounces ... and he's already got a nickname, "King."

"There is nothing comparable to witnessing your child being born ... I cried tears of joy."

But Peter says he couldn't be more proud of his wife -- "She's a true champion. She was in labor for 36 hours and was calm during the delivery."

And get this ... Peter says he already has big plans for his son -- "He will be a future champ and I just know we are going to shake up the boxing world!!!"

Jake "The Snake" Roberts was rushed to a Las Vegas hospital Wednesday night ... and doctors say he has double pneumonia.

The WWE Hall of Famer fell ill on a flight from Atlanta to Vegas ... and was immediately hospitalized when he landed. We're told he's been in and out of consciousness ever since.

Wrestler Sinn Bodhi -- who has been at Jake's bedside all night -- tells us Roberts went to a doctor 2 weeks ago, and was told he had the flu and needed rest.

Bodhi says Jake's been in pain since ... but didn't think it was a big deal because of the prognosis.

We're told Roberts is in ICU, and his immune system is in bad shape. Doctors are letting him rest for a few days while they take more tests.
