RIP

Bobbi Kristina Brown's official cause of death is eerily similar to her mother, Whitney Houston -- drowning while using a bunch of drugs, but the autopsy could not determine if there was foul play.

The Fulton County Medical Examiner's testing revealed Bobbi Kristina died due to "Immersion of face in water complicating mixed drug intoxication." The drugs found in her system were marijuana, alcohol, a cocaine-related substance called benzoylecgonine, benzodiazepines (prescription anti-anxiety meds) and morphine.

The ME could not determine if the morphine was related to heroin use.

The report lists the full cause of death as pneumonia and encephalopathy -- meaning her lungs filled with water and her brain was injured -- clearly caused by the time she spent submerged in her bathtub on January 31, 2015.

Whitney's official cause of death was drowning in her bathtub at the Beverly Hilton, complicated by cocaine use and heart disease.

Bobbi Kristina's autopsy results had been sealed until Friday morning because the Fulton County D.A. thought it would interfere with an ongoing criminal investigation into whether her boyfriend Nick Gordon was involved in her death. A judge unsealed the report after Atlanta station WXIA argued its First Amendment rights.

As for Gordon ... the ME was unable to determine if BK's death was "due to intentional or accidental causes." That could go a long way in clearing Gordon criminally.

However BK's estate has filed a $40 million wrongful death lawsuit against him -- alleging he gave her the toxic mix of drugs ... which the ME's report now clearly states played a role in her drowning.

Bobbi Kristina was eventually taken off life support and died on July 26 at a hospice in Georgia. Today would have been her 23rd birthday.

Lee Reherman's friends and family will pay their respects to the actor in true "Hawk Style" -- as in NO stuffy suits, and lots of time in the sand and his favorite bar.

Sources close to Hawk tell us his celebration of life will start on the beach and make its way to Shellback Tavern in Manhattan Beach, CA.

We're told there's a strict dress code: No suits or dark clothes and outdoor beach clothing is a must. Or as the invitation puts it, "anything that you would wear to party with Lee at the beach!"

As we reported Reherman died mysteriously earlier this week. We're told an autopsy is scheduled for Friday.

The 4-month old infant who was famously known as the "Bernie Baby" on social media ... has died from Sudden Infant Death Syndrome.

Oliver Jack Carter Lomas-Davis's mother Souxsie says her son died on February 25. She made the sad announcement on Facebook.

Oliver became a phenom when his mom dressed him up in a wig and glasses to look like Sen. Bernie Sanders and posted the pic online.

The senator actually got to meet his youngest (we're guessing) supporter a few weeks ago during a rally in Las Vegas.

Several good Samaritans ... including someone who appeared to be a doctor or nurse ... stopped to try to help Aubrey McClendon after his car crash -- but the fire proved to be too dangerous.

TMZ Sports obtained the 911 calls from the crash -- one caller says he actually witnessed the impact. The witnesses say McClendon's SUV swerved and crashed into the underpass and caught fire.

Another witness says people were running up to the car to try to help ... but noted the fire was "really escalating."

Eventually, the car burst into flames and another witness told 911 ... "There were people standing up there by the vehicle, which doesn't seem very smart to me."

Oklahoma City Police say suicide has NOT been ruled out in the fiery car crash that killed OKC Thunder co-owner Aubrey McClendon ... TMZ Sports has learned.

As we reported ... McClendon died when his car smashed into a bridge at an incredible high rate of speed Wednesday morning ... hours after he was indicted on a federal conspiracy charge that carries up to a 10 year prison sentence.

We spoke with OKC Police Dept Captain Paco Balderrama who told us ... cops are working on several possible theories that led to his death -- ranging from suicide to a medical episode behind the wheel.

"Anything is possible," Capt. Balderrama said ... "At this point we just don't know."

Cops say McClendon was NOT wearing a seat belt at the time of the crash -- and he made no attempt to slow down before impact.

OKC Thunder players Anthony Morrow and Andre Roberson say they're praying for the family of co-owner Aubrey McClendon ... who was killed Wednesday morning in a horrific car accident.

Aubrey McClendon -- co-owner of the OKC Thunder -- crashed his car into a bridge and killed himself in what appears to be a suicide mission ... one day after he was charged with conspiracy.

Lee Reherman -- aka Hawk -- had a strange, metallic taste in his mouth just hours before his death, sources close to the former "American Gladiators" actor tell TMZ.

We're told Lee's girlfriend urged him to go to the ER late Monday night when he began complaining about the metal-y taste.

A rep for Lee confirms he declined to seek medical attention, hoping to sleep it off. His girlfriend left the room to take a shower later that night and when she came back into the room, Lee had passed.

The actor's death seemed to come from out of the blue. We're told he'd been feeling great after his recent hip surgery and even began hitting the gym again.

Lee Reherman ... who was Hawk on "American Gladiators" ... was found dead in his house Tuesday morning, TMZ has learned.

Reherman's rep says the actor's girlfriend found him in their Manhattan Beach, CA home. The rep says 49-year-old Reherman had been complaining about "not feeling well" in the last week. He was also recovering from hip replacement surgery several weeks ago.

Reherman most recently played a secret service agent on the TV show, "The First Family" -- and guest roles on tons of other TV shows including, "Jane The Virgin," 'X-Files' and "NCIS." But he was best known as Hawk.

Cause of death is unclear at this point, but law enforcement sources tell us there's no initial sign of foul play.

George Kennedy, star of "Cool Hand Luke" and the 'Naked Gun' movies, has died at the age of 91 ... TMZ has learned.

George's grandson Cory Schenkel says Kennedy died Sunday morning at 4:30 AM in Boise, ID. He says his grandfather had been in failing health ever since his wife Joan died a little over a year ago. George had been under hospice care for the past month.

Kennedy won the Best Supporting Actor Oscar in 1968 for "Cool Hand Luke." He also starred in all 3 of the 'Naked Gun' flicks, "Airport 1975," "Earthquake" and many many more.

His last role was in "The Gambler" with Mark Wahlberg in 2014.

Abe Vigoda's family is demanding an apology from the Oscars, saying leaving him out of the "In Memoriam" segment was a final injustice to his memory and career.

Carol Vigoda tells TMZ ... "Last night the Oscars dismayed many and cheated Abe Vigoda by not paying tribute to the immense professional energies and talents that he brought to the industry."

She added, "Let's not forget the personal and family sacrifices that were willing made to achieve that essential devotion. The Oscars fell short in many ways and as my father Abe Vigoda said the Oscars have earned, 'one demerit.'"

Carol's also not going to buy the excuse that Abe -- who starred in "The Godfather," "Look Who's Talking" and countless other films -- was omitted because he died too recently (Jan. 26, 2016) because David Bowie was included ... as was Alan Rickman.

Carol says there's a "hole in my heart that needs to be filled."

Tony Burton, one of only a handful of actors to appear in the 1st 6 installments of the 'Rocky' franchise, has died.

Burton played Duke, Apollo Creed's trainer, and also trained Rocky in the 4th movie. Prior to acting Burton was himself a professional light heavyweight boxer and football player.

Burton was apparently ill and unable to see 'Creed.'

The actor also starred in "The Shining" and "Stir Crazy."

'Rocky' co-star Carl Weathers confirmed the death in a tweet, "RIP Tony Burton. intensity and talent helped make the Rocky movie successful #BePeace."

Burton was 78.

R.I.P.

Elvis Presley's longtime doctor -- who stood trial for over-prescribing Presley -- died in Memphis on Wednesday at the age of 88.

Dr. George Nichopoulos was infamously known to Elvis fans as "Dr. Nick" and much like Conrad Murray after Michael Jackson's death -- he came under heavy scrutiny when the king of rock 'n' roll died.

Dr. Nick traveled with Elvis as part of his entourage, but after Presley died in 1977 ... the doc faced criminal charges for negligently dishing drugs to Elvis. Unlike Murray, he was acquitted in 1981.

He did eventually lose his medical license for over-prescribing addictive drugs to several patients, including Presley and Jerry Lee Lewis -- but remained adamant all the meds he gave Elvis "were necessities."

Taryn Manning got a visit from the ghost of movies past -- her former co-star Brittany Murphy -- right in the middle of her DJing gig ... or at least she thought so.

Taryn was spinning for an H&M party in Toronto when she played Eminem's "Lose Yourself" from "8 Mile" ... which, of course, co-starred Taryn and Brittany.

Watch what happened when she shouted out Brit, who died in 2009. Manning seems convinced spirits are a thing.

Then again ... someone just coulda tripped over a power cord.

Robert Kardashian may be gone, but his memory burns bright, because almost the entire Kardashian brood turned up to celebrate what would have been his 72nd birthday.

Kris Jenner hosted the bash at her Calabasas home. Kim, Kourtney, Khloe, Kendall, and Kylie were all there, dining on traditional Armenian food, including, hummus, pita bread, stuffed vine leaves, bulgur wheat, string cheese and baklava.

Interestingly, we're told Lamar Odom and Scott Disick were also there.

Celine Dion will return to her Vegas stage Tuesday for the first time since her husband Rene Angelil died, and she plans to continue paying respect to him.

We're told Celine's completely changing her show at Caesars Colosseum -- it now begins with a 10 minute long tribute to Rene.

Celine has 12 shows before going on hiatus in mid-March, so the tribute will be part of the act at least through then.

As her manager, Rene played a huge role in catapulting Celine to stardom. She's already had an emotional send-off for him at Montreal's Notre-Dame Basilica and a Vegas ceremony to honor him. Tomorrow night's opener should be another tearjerker.
