Britney Spears says she's got a fever so bad, it feels like it could be the end ... and, yet, she's still taking shots at her sister Jamie Lynn over her book and recent interview.

Brit just posted a long rant, detailing her symptoms ... saying she had a 104-degree fever Wednesday night and complained her security wouldn't leave to get her Aleve. She admits she's being a drama queen by saying she's possibly dying, but says she never gets sick.

While Britney makes her illness sound very unpleasant -- drama queen or not -- she says it actually made it easier to stomach Jamie Lynn's interview with "Nightline" ... even though Britney's got some big issues with what was said.

Britney's got 2 bones to pick with Jamie Lynn ... saying it's ridiculous she said Britney was out of control 15 years ago. Britney says her sister was not around her enough to speak on the topic and chalks it up to Jamie Lynn trying to pump up book sales.

The other issue Britney has involves Jamie Lynn remixing some songs ... and you can read her full rant about everything.

Britney's also railing on her security for not getting her some pain meds, comparing it to the way she feels she's been treated by her family

Bottom line ... she says her relatives just love to bring her down, and that's why she prefers cats and dogs. That's ruff.

Rob Gronkowski ain't just worried about the Eagles this week ... he's got dogs on his mind too -- 'cause his adorable pup, Ralphie, is sick.

The Buccaneers tight end and his girlfriend, Camille Kostek, shared the news on social media Wednesday -- just days before Tampa's playoff game against Philadelphia -- explaining poor Ralphie has some kind of lung infection that's been keeping him up at night.

Kostek revealed she and Gronk took the fur baby to the vet this week ... after the dog had been breathing abnormally, not sleeping and not eating.

"He was waking up pretty much every hour on the hour, having some kind of wheezing fits," Kostek said. "His regular breathing is off. He's been super uncomfortable."

Thankfully, Kostek said the issue does not appear to be too serious -- with the vet prescribing some meds after discovering a lung issue.

Kostek said she's hoping Ralphie is better in a few days.

She and Gronk, meanwhile, have been firing up the steam room for their dog with the hope that it helps the animal breathe better too.

Jamie Lynn Spears says she's in no position to evaluate Britney Spears' mental state, but that's exactly what she did in her book, clearly suggesting her big sister had mental issues.

In an interview that aired Wednesday night on "Nightline," Jamie acknowledged she wrote in her memoir that over the years Britney's conduct was "erratic," "paranoid" and "spiraling."

She described an incident in the book where she says Britney took a knife, and locked herself and Jamie Lynn in a room, saying she was scared. As for why she included the story ... Jamie Lynn essentially said the book was a memoir and she was recounting stories that had an impact on her life ... namely, she says she suffers panic attacks from past trauma.

Up to now, it seemed Jamie Lynn was trying to extend an olive branch to Britney, but based on what we now know she's saying in the book, she's clearly trying to make a case that Britney has serious mental issues.

She also says her relationship with Britney fell apart during the pandemic, recounting a story where she says Britney was holding her toddler, Ivey and got in Jamie Lynn's face, cursing at her. Jamie Lynn says her 12-year-old daughter tried to mediate the situation. As for their parents' reaction ... Jamie Lynn says it was simple ... Don't Upset Britney -- and that angered Jamie Lynn.

Bob Saget very privately turned a personal tragedy in his life into a mission to spare others similar grief ...  and a 9-year-old girl named Sophie Anne and her parents are forever grateful.

Sophie Anne is afflicted with Scleroderma, a group of rare diseases that involve the hardening of the skin and connective tissues. It's a disease that took the life of Bob's sister, Gay, who died in 1994 at age 47.

Bob became a tireless advocate and fundraiser for the Scleroderma Research Foundation, but we found out he also reached out to families suffering from the illness to offer comfort and support.

Bob found out about Sophie Anne roughly 2 years ago, after she was diagnosed.  Her parents, Martha and Jeff Seaman, tell us they felt they were in the middle of the ocean without any lifeline, when suddenly, Bob came into their lives.

Bob sent the little girl personalized videos, always with comfort and hope ... "We are going to find a cure, sending lots of love."

Bob knew how the disease affects an entire family, so he offered support to Sophie Anne's sister with a school paper. The paper she chose to write, "Bob Saget: My Everyday Hero." We're told Bob was incredibly patient and candid about his life ... spending more than 30 minutes with her on the phone.

It didn't stop there. Just a few months ago, Bob invited Sophie Anne's parents to his show in North Carolina. He comped their tickets, meals and brought them backstage after his show.

The Scleroderma Research Foundation is benefiting from the massive goodwill embodied in Bob. More than 1,200 people have donated a total of more than $80,000. And, people are learning about the disease because of Bob's good work.

Hollywood execs and celebs who were planning to attend this year's Sundance Film Festival are in for a rude awakening ... because the event was canceled just days beforehand and now they stand to lose a boatload of cash.

This year's Sundance was scheduled for Jan 20-30 as a hybrid event with both in-person and online events ... it was expected to bring out filmgoers from around the U.S., volunteers and, of course, celebs and Hollywood honchos.

Well, that was until the festival was canceled only 15 days before the curtain was raised, due to the explosion of COVID. We're told hotels and Airbnb jacked up the prices like crazy -- $3k and up for some rooms and suites -- and now we're told a lot of them are not giving refunds.

Likewise ... Sundance organizers are not offering refunds to folks who paid to attend in person. Instead, attendees can either gift their packages to someone else or turn the money spent into a tax-deductible donation to the Sundance Institute.

Back to the hotels ... one example is Auberge Resorts Collection, which was charging $3,798 per night for some of the suites ... and guess what, it's non-refundable. The hotel is telling guests to come anyway and enjoy the skiing, or just reschedule.

When COVID strikes this way, a lot depends on what's in the contract.  If there's an "Act of God" clause, although it's not clear there have been successful arguments that money should be returned.

Life has changed so much for Shawn Bradley since he was paralyzed in a tragic bike accident last year, the former NBA star admitted he battles suicidal thoughts regularly.

The 7-foot-6, ex-Dallas Mavericks fan favorite made the revelation during recent interviews with Sports Illustrated -- explaining things have not been easy since he suffered a serious spine injury in a Jan. 20, 2021 bicycle crash.

"Maybe it'd be better if this was just all over," Bradley says he sometimes thinks to himself in the wake of the tragedy.

"Yes, those thoughts creep in -- and they're real. I can't ever imagine myself acting on those thoughts, but I definitely have them."

Bradley revealed that when a minivan bumped into the back of his bike in the accident last year, he landed on a parked car and damaged vertebrae in his neck so badly, he was paralyzed from the chest down.

Because of the injury, the once towering basketball player has been relegated to a wheelchair -- which he and his wife, Carrie, said have made even the simplest tasks, like going out on dates or even getting around his home, nearly impossible.

Bradley now needs help eating and bathing ... and he says when friends and former teammates have seen him in his new state, it can get overwhelming.

"People that I'm very close with, the first time they see me, it's emotional," Bradley said. "It's extremely draining."

Bradley, though, says he has realistic goals of improving his ability to move around his big frame in the near future. He said the family is also hoping to move into a more wheelchair-friendly home soon.

Novak Djokovic is navigating waters that have gone from warm to boiling, because the tennis star admitted he knew he had COVID when he posed for a photo shoot and chatted with a reporter from a French magazine.

Beyond that ... Djokovic attended multiple public events and posed for photos on December 16 and 17 -- in particular the 17th, when he handed out awards at a children's event -- but he says that shouldn't be held against him, because he got a negative rapid test on the 16th.

However, he also took a PCR test that same day that turned out to be positive. The Serbian government's records show that result came back at 8:19 PM on the same day -- but Novak insists he didn't get the info until the evening of the 17th.

So, the question is ... what did he know and when???

Whatever the case, he still did the photo shoot with L'Equipe magazine in Belgrade on the 18th when he knew he was positive.

He says, aside from the actual shoot, he was socially distanced from the reporter and photographer and masked. Djokovic now says he made a mistake and should have canceled.

He also acknowledges his visa application was incorrect ... he says his agent checked the wrong box, declaring Novak had not traveled internationally, which he very clearly did.

Djokovic, the number 1 seed in the Australian Open, was allowed into the country after the tournament granted him a medical exemption ... because he had just gotten over COVID and had antibodies, that apparently qualified.

Howard Stern is unloading on Novak Djokovic over his COVID-19 vaccine drama ... calling the tennis superstar a "d****bag," "f***ing a**hole," and a "f***nut" in a fiery rant.

34-year-old Djokovic has been fighting like hell to compete in the Australian Open this month despite the country's strict COVID-19 mandates -- he initially had his visa canceled after authorities claimed he did not meet requirements for a vaccine exemption ... before that decision was overturned on Monday.

Stern -- who's gone after sports stars like Kyrie Irving and Aaron Rodgers for their vax stances in the past -- sounded off on the Joker during Monday's episode of "The Howard Stern Show" ... saying Novak should be kicked out of the sport.

"The first I heard of this guy is he doesn't want to get the vaccine, he's running around ... they should throw him right the f*** out of tennis," Stern said.

"He's a d****bag."

But, what really set Howard off is Novak's claim that getting the jab is a private decision ... saying if that's the case, he shouldn't be out in the public and putting everyone else's health at risk.

Howard's co-host, Robin, points out Novak's view on the situation -- his people have claimed since he recently had COVID-19, he doesn't have to get vaccinated, but Stern says Novak can't be trusted.

"Well that's like saying smoking is a private decision," he added. "Well, that's true, but don't smoke in my face, f***nut. What a dummy. Just a big, dumb tennis player."

Djokovic -- the reigning AO champ -- is currently preparing to compete in the tournament next week ... although it's still unclear whether he'll actually be able to take the court ... as government officials could still boot him from the country.

Kyrie Irving was not pleased with Nassir Little Monday night -- the Brooklyn Nets star claims the Blazers forward could have seriously injured him while diving for a loose ball in the middle of the game ... calling the move "unnecessary."

Check out the play -- both players were trying to secure possession during the 4th quarter ... when Nassir dove to the floor, causing Kyrie to land awkwardly while trying to avoid stepping on Little.

Irving tweaked his ankle as a result ... but managed to finish the game. He spoke with reporters about the moment during postgame interviews ... saying it was a "bad" play.

"I tried to get out of the way, but I just felt like that was just unnecessary," he said.

"For him to dive that far to the ball, I just tried to get out the way. Just an unnecessary play."

Kyrie -- who's only playing in Brooklyn's road games at the moment due to his COVID-19 vaccination status -- says he spoke with refs ... telling them they need to do a better job of protecting players.

"I could have broke my ankle or done something worse," Irving said. "Not a good play. No place for that in basketball."

"I get the intent from Nassir, but it could've been avoided. All good, we move on."

Little got wind of Irving's comments ... and doubled down on the play via Twitter.

"I would never hurt someone on purpose, I have the utmost respect for Kyrie!" he said. "But y'all are delusional if you think this is a bad play, and id do it again."

"Idgaf what y'all talkin about."

Despite the tweaked ankle, Irving says he'll be ready to go when the Nets take on the Chicago Bulls on Wednesday.

Bob Saget's cause of death might not be determined for weeks, but law enforcement working the case see signs pointing to a sudden medical emergency -- specifically a heart attack or stroke ... TMZ has learned.

Law enforcement sources tell TMZ ... authorities involved in the investigation say the position in which Bob's body was found, and a lack of evidence supporting drug use or foul play are the main reasons they suspect a heart attack.

TMZ broke the story ... Bob was found in his Ritz-Carlton Orlando hotel room by security. Cops say the comedian was lying face-up on the bed, with his left arm across his chest, and his right arm lying beside him. We're told the hand on the chest could point to a heart attack.

Our sources say authorities are exploring Bob's revelation last week that he'd recently battled COVID-19. Developing blood clots has been reported as a possible complication from the virus.

Of course, we're told a final cause can't be determined until the medical examiner gets Bob's toxicology results. The Orange Co. M.E.'s Office says it could take 10-12 weeks to complete.

Saget performed a standup show in Jacksonville Saturday night before making the 2-hour trek to Orlando.

Novak Djokovic is making sure he's ready for next week's Australian Open despite uncertainty he'll be allowed to remain in the country -- hitting practice courts hard Down Under on Tuesday.

The tennis superstar was spotted getting in a lengthy workout at Rod Laver Arena in Melbourne ... hitting balls and sweating just six days away from the start of the big tournament.

Of course, Djokovic needs all the practice he can get ... considering he was cooped up in a hotel for nearly a week after Australian authorities tried to bar him from entering the country.

Djokovic and law enforcement feuded over his COVID-19 vaccination exemption status ... but after the 34-year-old won a key appeal on Monday, he was let into the country so he can gear up for The Open.

And, by the looks of things, Djokovic seems to be ready to defend his title. In the photos, Novak appears to be in good shape.

Djokovic is still not 100 percent certain about his status for the event ... Australian authorities are still exploring the possibility of canceling his visa a second time -- which could lead to a three-year ban from the country for the tennis player.

Bob Saget's family was desperately trying to get a hold of him, not knowing he'd died in his hotel room -- and cops are now painting a more complete picture of what they found there.

An Orange County Sheriff's Deputy noted in his official report that Bob was discovered by a Ritz-Carlton Hotel security staffer who'd been sent to the room on the Saget family's request ... after they'd made several unsuccessful attempts to reach him Sunday.

In the docs, obtained by TMZ, the deputy notes this staffer knocked on Bob's door multiple times before going in around 4 PM ET ... only to find all the lights off. Upon entering the bedroom, they found Bob lying face-up on the bed, with his left arm across his chest and right on the bed.

The staffer says he was cold to the touch ... and when they checked for signs of breathing or a pulse, none was detected.

Upon arriving, EMS personnel pronounced Bob dead on the scene.

Another interesting tidbit, the Ritz was able to pinpoint that Bob had last entered the room at 2:17 AM. He was scheduled to check out later that same day. He tweeted this message and photo shortly before that, at 12:42 AM, showing himself onstage in Jacksonville ... about a 2-hour drive from Orlando.

The deputy points out there were no signs of foul play or trauma. Bob's next of kin was listed as his wife, Kelly Rizzo, who was notified about his death.

For the first time ever, surgeons transplanted a heart from a genetically modified pig into a human patient, in order to save his life ... If all goes well, this could be the start of life-saving treatment for many patients in dire need.

57-year-old David Bennett received a heart like no other ... He was ineligible for a human transplant and, while doctors couldn't guarantee the transplant would work, the surgery was a matter of life or death, so he rolled the dice.

“It was either die or do this transplant. I want to live. I know it’s a shot in the dark, but it’s my last choice,” he said before undergoing the 7-hour surgery Friday at a Baltimore hospital.

The FDA had approved the operation for emergency use, since David had no other options.

Though it's still unclear if the transplant will actually take, he seems to be doing well days after the surgery... And, docs at the University of Maryland Medical Center say his transplant showed a heart from a genetically modified animal can work inside a human body without immediate rejection.

That's great news, because in the past such transplants failed because the patient's body would reject the animal organ. Now, Maryland surgeons used the heart from a pig that had received gene-editing ... to thwart rejection.

Bob Saget's recent bout with COVID-19 was fresh on his mind not too long before he died ... this according to the late comedian himself.

BS appeared on a podcast called "A Corporate Time with Tom & Dan" just last week and revealed he had already caught the 'rona. He wasn't specific about exactly when, but it sounded kinda recent, considering he was humorously debating whether he had omicron or delta.

Check it out ... Bob describes the virus as "not good," and cracks some jokes about which strain he might've had. He also explained what it was like performing comedy during the pandemic, saying audiences would often be dwindled down by at least half.

Eerily, he also jokingly said he might die from COVID.

Another topic brought up here is Bob's friend, Norm Macdonald, who died last year from cancer. He said there's dignity in the way NM handled his diagnosis, keeping it secret from almost everyone he knew.

Bob actually sounded ill on the phone, which the hosts noted once he left the chat. It's not clear if he was still under the weather while on the road there in Florida -- this podcast was recorded just after the New Year.

We've reached out to Saget's reps for clarification on when he had COVID, but no word back yet.

Tributes have been pouring in about Bob Saget, and how he touched so many lives, but few are as poignant as Pete Davidson's .. who says Bob stepped up for him during some pretty dark times.

Pete does not hop on social media -- period, but he made an exception for Bob, whom he called "one of the nicest men on the planet."

Pete wrote, "When I was younger and several times throughout our friendship he helped me get through some rough mental health stuff."

But, it wasn't just a "Hey, how ya doin'" call. Pete says Bob was genuinely concerned and wanted to help ... "He stayed on the phone with my mom for hours trying to help in anyway he can -- connecting us with doctors and new things we can try. He would check in on me and make sure I was okay."

It's one of a slew of tributes to Bob. TMZ broke the story, he died Sunday in an Orlando hotel room at age 65.

Novak Djokovic has just been set free Down Under -- a judge ruled in his favor in his visa appeal case, clearing the way for the tennis star to compete in the Australian Open next week.

Djokovic had been in a quarantine hotel in Melbourne the last few nights ... after Australian government officials canceled his visa shortly after his arrival in the country last Wednesday.

Authorities argued Djokovic did not meet the proper requirements to be formally granted an exemption to Australia's strict COVID-19 vaccination rules.

Djokovic, though, argued he did meet all the criteria ... saying he had been infected with COVID last month and therefore did not need to be vaccinated.

At a visa appeal hearing in an Australian courtroom on Monday -- a judge overturned the government's decision, pointing out that the 34-year-old had received vaccine exemption status from Tennis Australia and two medical panels prior to his arrival.

"The point I’m somewhat agitated about is what more could this man have done?" the judge said in the courtroom.

The judge's decision now paves the way for Djokovic to compete in The Open, which begins on Jan. 17.

"I'm pleased and grateful that the Judge overturned my visa cancellation," Djokovic said in a statement on Twitter following the decision. "Despite all that has happened, I want to stay and try to compete @AustralianOpen."

"I remain focused on that. I flew here to play at one of the most important events we have in front of the amazing fans."

There could still be more hurdles for Djokovic to leap ... Australian authorities have suggested they could still cancel his visa once again.

If that does happen, and Djokovic is deported, he could be faced with a 3-year ban from the country.

It remains unclear what the likelihood of a second cancellation is.
