RIP

Kimbo Slice was told he had been suffering from congestive heart failure in the days before his death and desperately needed a heart transplant ... this according to a hospital report.

The report -- which was given to the Broward County Medical Examiner's office -- says Slice was admitted to Northwest Medical Center on June 3rd and told he had a liver mass and congestive heart failure.

Doctors told Slice's family that he needed a heart transplant -- and appeared to be taking measures to transport him to a clinic in Cleveland on Monday night ... but he died before that could happen.

Slice was pronounced dead around 7:30 PM local time.

Also worth noting ... the report also states 42-year-old Slice did not have a history of drug use.

Bretagne, the 16-year-old golden retriever hailed as the last of the 9/11 search dogs, has died.

Bretagne was euthanized Monday, according to firefighters in Houston ... where she had been a founding member of the K9 Search & Rescue Team.

She put up some true hero stats over her career. As part of Texas Task Force 1, she and handler Denise Corliss spent days searching through Ground Zero for trapped victims. Bretagne also pitched in on rescue efforts during Hurricanes Katrina and Rita.

She left active duty at 10, but continued serving as a community ambassador.

Bretagne was given a hero's salute on her last walk into the vet's office and her body was draped with an American Flag on the way out.

Actress Theresa Saldana who played the commissioner's wife on '90s cop drama "The Commish" and was the victim in a highly-publicized stabbing has died ... TMZ has learned.

Saldana had been hospitalized with an unknown illness and died Monday at Cedars-Sinai ... according to a member of her family.

The actress made headlines in 1982 after being stabbed by a deranged fan outside her L.A. home. A delivery man who happened to be driving by saw her and came to her rescue, and she was able to survive the attack.

Saldana also famously starred alongside Robert De Niro and Joe Pesci in "Raging Bull."

She stopped acting in 2004.

She was 61.

Kimbo Slice's body will not be tested for things like steroids or drugs ... at least, not by the medical examiner's office which tells TMZ Sports there's nothing suspicious about Kimbo's death.

After the 42-year-old passed away suddenly near his home in Coral Springs, FL Monday -- we reached out to the Broward County Medical Examiner to find out if an autopsy would be performed.

We were told ... "We were informed of his death and after review of the circumstances, we declined jurisdiction. It is not a medical examiner case."

We asked if that meant the office believes his death is not suspicious and there's no need for toxicology tests -- to which the M.E. Chief told us, "No medical legal investigation, including toxicology is necessary.”

Slice reportedly tested positive for a banned steroid during his fight at Bellator 149 back in February.

Ken Shamrock says his heart aches for Kimbo Slice -- saying the guy made a tremendous impact in the world of combat sports ... but never got the respect he truly deserved.

Shamrock -- who fought Slice (and lost) last year -- says Slice made one helluva splash in MMA and boxing ... but still had to battle extreme negativity from haters -- even when he won his fights.

"Even when he won a fight it seemed like he was never good enough," Shamrock says.

"When you really care about your fans and you really care about what you do then those things that come at you from a negative position ... it hurts ... especially when it comes in thousands of people with negative thoughts. It stings, it hurts."

Shamrock says he never spoke with Slice directly about it -- but says it was obvious Kimbo was affected by the negativity.

Kimbo Slice was an inspiration -- a guy who turned nothing into something -- and he'll be missed ... so says rapper The Game.

Game is a huge fight fan -- and says Slice's story about going from strip club bouncer to one of the most famous fighters in the world is nothing short of amazing.

"Just being an African American and coming from the hood ... I think that Kimbo Slice is one of those stories that gives people hope."

Check out the clip ... Slice clearly meant a lot to Game -- and he explains the lesson that people should learn from the tragedy.

Kimbo Slice has died ... TMZ Sports has confirmed. He was 42.

George Foreman says the legendarily nasty public feud between Muhammad Ali and Joe Frazier was actually friendly behind closed doors ... telling TMZ Sports the two men secretly loved each other.

The war between Ali and Frazier is well-known -- Ali called him names like "gorilla" and "Uncle Tom" -- which reportedly wounded Frazier until his death in 2011.

In fact, Frazier famously expressed his distaste for Ali in a 1990 interview -- "I hated Ali. God might not like me talking that way, but I hated that man. First he made me a white man, then he made me a n****r.”

"How would you like it if your kids came home from school crying because everyone was calling their daddy a gorilla?"

But when Foreman -- who called Ali his "best friend" -- joined the guys on the "TMZ Sports" TV show (airs tonight on FS1) ... we asked if Ali privately regretted taking things so far with his old foe.

Check out the clip ... Foreman says he was tight with both men and knows they all had love for each other.

"Whatever names we were called, they were all taken as a joke."

Laila Ali says she has "comfort" in knowing her father is "not suffering anymore" ... saying she felt Muhammad Ali was "trapped inside of his body" during his battle with Parkinson's.

Ali spoke with Robin Roberts on 'GMA' and said all 9 of Ali's children flew in to Arizona to be with their dad in his final moments.

Laila says some of her sisters recited Islamic prayers at his bedside -- she says it was "a very peaceful time."

Laila says she's also grateful her 5-year-old daughter, Sydney, got to spend time with the legend in the years before he passed. She even tells some heartwarming family stories.

#RIP.

Muhammad Ali has died in a Phoenix-area hospital where he was battling respiratory issues ... according to a family spokesman.

The legendary boxer and humanitarian was 74 years old. He had checked into the hospital on Thursday and reps said he was in fair condition, but on Friday his health worsened throughout the day.

The family says his funeral will be held in Ali's hometown of Louisville, although the spokesman didn't specify a date. NBC News first reported his death.

Ali will be remembered as one of the most recognized figures worldwide -- after winning boxing's heavyweight title 3 different times ... with the first coming in a KO of Sonny Liston in 1964.

He was as famous for his boxing matches -- the "Rumble in the Jungle," the "Thrilla in Manila" -- as quotes like, "Float like a butterfly, sting like a bee."

Ali, born Cassius Clay, changed his name and converted to Islam in 1964. He also famously refused to enter the Vietnam War in 1967 as a conscientious objector.

Although he was diagnosed with Parkinson's Disease in 1984 ... Ali remained very active at international events in and out of the sporting world. His lighting of the Olympic flame at the 1996 Atlanta games is considered one of the most iconic images in Olympic history.

The champ is survived by his wife Yolanda Williams and 9 children -- 7 daughters, 2 sons -- including Laila Ali, who became an undefeated boxing champ herself.

When he retired in 1981, Ali had 56 wins, 5 losses and 37 knockouts.

He was inducted into the International Boxing Hall of Fame in 1990 ... and will always hold the title of "The Greatest."

The clothes Prince died in match the outfit he was wearing the night before when he made that frantic run to a Walgreens pharmacy ... and the drugstore run could prove crucial in the investigation.

The Medical Examiner's report describes the clothes Prince was wearing when his body was found -- a black cap, a black shirt, a grey undershirt, black pants, black boxer briefs and black socks.

You can see from the photo TMZ posted -- taken at 7 PM the night before he died -- everything visible matches that description.

As we reported, Prince was at Walgreens to fill a prescription and eyewitnesses told us he was pacing and nervous as someone went inside and got the Rx.

TMZ also broke the story, a Walgreens was targeted by investigators and a search warrant was executed at the location.

The ME concluded Prince died from toxic level of Fentanyl.

Bobby Brown lost it while describing the moment he decided to turn off Bobbi Kristina's life support.

Brown sat down with ABC's Robin Roberts to talk not only about his daughter's death, but also his ex-wife Whitney Houston.

The singer covers a lot of ground -- including the first time Bobby saw Whitney do drugs, and how addiction affected their marriage and his finances. The interview airs next week on "20/20."

Andrew Kornfeld, the man who called 911 when Prince died, firmly believes he could have saved the singer with the backpack full of opioids he had at Paisley Park that morning.

The ME's report revelation that Prince died from a self-administered dose of Fentanyl ... seems to acquit Kornfeld and his father, Dr. Howard Kornfeld, of any involvement in the death. Andrew was delivering an opioid called Buprenorphine to treat Prince's addiction to Percocet. He insists Prince never took the drug.

Now Kornfeld is singing the praises of the synthetic opiate, saying it should be more accessible to addiction patients everywhere. Kornfeld tells CNN, he believes part of Prince's problem was that Buprenorphine is very difficult to get in Minnesota.

TMZ has obtained Prince's

... which lists, among many other things, his official time of death as 10:07 AM on April 21.

That detail is a little misleading -- that's the time he was pronounced dead by paramedics on scene at Paisley Park. It's not the time he actually died ... since it's possible the singer had passed away long before authorities arrived.

Prince's death has triggered a criminal investigation over how the singer got the opioid that killed him ... and our sources say it's more complicated than a simple prescription.

Sources connected with the investigation tell us they have known "for a long time" that Fentanyl -- an incredibly potent opioid up to 100 times more powerful than morphine -- was the cause of death.

Law enforcement sources tell us the investigation has focused on the "illicit" possession of the drug.

One law enforcement source would not confirm the basis of the investigation, but mentioned one trigger for a criminal probe would be if a doctor prescribed meds to a third party knowing the drug was going to someone else. We don't know if Rx bottles in someone else's name were found at Prince's home at the time of death.

We're told both state and federal prosecutors are investigating both how Prince got the drug and who facilitated it.

As we reported, authorities already obtained a search warrant for Prince's primary physician. They also executed a search at a Walgreen's pharmacy that filled a prescription for the singer. We don't know if authorities found a connection between the doctor, the pharmacy and the Fentanyl that killed Prince.

Prince died from an opioid overdose ... it's now official from the Midwest Medical Examiner's Office, and the drug is even more powerful than Percocet.

The M.E. performed toxicology tests on the singer and determined the singer died of an accidental overdose of Fentanyl -- a powerful synthetic opiate that is more potent than morphine ... often used for cancer patients to deal with severe pain.

Fentanyl is often used to treat people who have developed a tolerance to less powerful opiates such as Percocet and morphine.

And this is important ... there were several reports Prince had either AIDS or HIV, but the report says there were no "other significant conditions" that led to his death ... clearly refuting the stories.

According to the report ... Prince was discovered fully dressed ... wearing a black cap, black shirt, gray undershirt, black pants, black boxer briefs and black socks.

Also interesting ... Prince weighed a petite 112 lbs and stood 5'3" at the time of his death.

We broke numerous stories -- Prince was addicted to Percocet. As we first reported, Prince's private jet was forced to make an emergency landing when the singer almost died after ODing on Percocet 6 days before he was found dead in an elevator.

Prince had made at least 4 trips to a local drugstore in the week preceding his death ... to fill prescriptions.

His addiction was so bad his people called a rehab doctor in California to get him emergency help. The doctor's son flew out to Minnesota and was in the Paisley Park compound -- with a backpack filled with synthetic opioids -- when the 57-year-old singer was found dead. The doctor's son, who is not himself a doctor, denies giving Prince any of the pills.
