Carlton Gebbia was barely conscious while being loaded into an ambulance Friday night, and it appears alcohol is to blame ... TMZ has learned.

The 'Real Housewife of Beverly Hills' star appeared unresponsive outside Bootsy Bellows. She was eventually put into a wheelchair before paramedics arrived and placed her on a stretcher.

Sources tell us an ambulance was called to transport an unconscious female.

Multiple sources tell us they believe Gebbia's condition was caused from excessive alcohol while in the club.

It's unclear how long she was hospitalized, but sources close to the 'Real Housewife' tell us she was resting at home on Sunday.

We reached out to Carlton, so far no word back.

A guest at Disney's Grand Floridian Resort saw an alligator looming in the area where 2-year-old Lane Graves was playing ... and she even sounded the alarm to someone at the hotel.

The Florida Fish and Wildlife Conservation Commission and the Orange County Sheriff's Office released a final report -- obtained by TMZ -- about the circumstances surrounding Lane's death.

According to the report, Shawna Giacomini, a North Carolina tourist, told investigators she was on the beach at 8:15 PM with her 2 daughters, and the girls saw an alligator about 5 feet from the shore, near the marsh. The older daughter told the Walt Disney World AV/Movie Coordinator about the gator.

The trio went to the store, and when they returned at around 9 PM the attack had already occurred.

The report details the attack, explaining Lane went toward the water with his dad and a pail. The dad saw a splash, looked over and saw the gator had locked onto Lane's head. He tried pulling the gator's mouth open, to no avail, and the gator dragged Lane into deep water.

The cause of death was cranio-cervical trauma and drowning.

The report is damning because of the lack of signs warning of gators, which the authors call "predatory."

Lou Pearlman died from an ongoing cardiac problem ... TMZ has learned.

According to the Miami-Dade Medical Examiner's Office, the mastermind behind the Backstreet Boys and 'NSYNC ... died at a Miami hospital where he was scheduled to have heart surgery. 

We're told 62-year-old Pearlman had been transferred from his prison cell to have the surgery, but as we reported ... he died Friday -- before the procedure. He had a history of cardiac issues.

The official cause of death is listed as natural causes.

Prince's deadly dose of the powerful painkiller Fentanyl was NOT prescribed by a doctor, which means it's a near impossibility anyone will ever be charged with his murder.

Law enforcement sources confirm investigators have not turned up a prescription for the Fentanyl. The Fentanyl pills found at Paisley Park were in a bottle labeled hydrocodone -- and it's now believed they were illegally obtained.

Our sources tell us whoever gave Prince the drug would face a 3rd degree murder charge under Minnesota law. However, without a prescription, we're told Prince's doctors would be in the clear ... so there'll be no Conrad Murray-esque trial.

Investigators would have to track down the source of the illicit Fentanyl -- it's reportedly an epidemic problem in Minnesota -- for anyone to stand trial for murder.

It's still possible a doctor could get nailed for over-prescribing other opioids. Remember, we broke the story ... Prince nearly OD'd on Percocet 6 days before his death at Paisley Park. 

Chris Brown just scored a W in his legal battle with his pissed off neighbors -- who, for some reason, backed down and now the LAPD's dropped its disturbing the peace investigation.

Law enforcement sources tells us Chris won't face any charges for allegedly disturbing the peace back in May ... when he was accused of terrorizing the streets of his neighborhood on an ATV.

You'll recall ... there was even video of a joyride taken by one of his neighbors. We're told the one who ended up calling cops didn't want to cooperate, so LAPD decided to close the case.

You gotta wonder why the neighbors suddenly went soft. One of 'em was on "TMZ Live," and seemed determined to go the distance with Brown. Hmm ...

Drake walked right into Meek Mill's house and took a big ole metaphorical dump on his living room floor by not only performing "Back to Back" ... but adding a new, personal shot.

Drake performed Sunday night in Philly -- Meek's hometown -- and refused to take his foot off Meek's throat. Seriously, we thought at this point this beef was well done ... but Drizzy went HAM.

Check out his message to Meek at the end of the diss anthem -- he made sure the crowd knew it wasn't about Philly, in general ... and only about Nicki's BF.

Everyone shoulda seen this coming after Drake's Saturday night gig in D.C. ... where he flat out called his nemesis a p****.

Who's not letting it go now?

Eddie Cibrian is washing his hands clean of ex Brandi Glanville by getting rid of their L.A. starter home.

Eddie got $635k for the 3 bedroom, 3.5 bath townhouse in Toluca Lake, CA. He'd originally listed it for $100k more than that back in February -- but we're guessing LeAnn Rimes is just thrilled to unload the tie to his ex. 

Eddie and Brandi shared the pad in happier times ... aka before the bitter divorce. 

The pad is 1,800 square feet with a rooftop patio overlooking the Hollywood Hills. Alex Galuz of Crescent Realty Corp closed the deal for Eddie.

Whitney Cummings is livid at a neighbor who she claims went all Paul Bunyan in her backyard, and now cops are investigating. 

We're told Whitney walked in her backyard this week and was horrified to see a tree massacre, courtesy of her neighbor's gardener.

Seems the neighbor was frustrated that Whitney's wall of bark was blocking his view, and she says he ordered the landscaper to do a hatchet job on her property ... cutting the trees down to stumps.

Whitney called the cops, who came out and took a felony vandalism report ... she claims the damages total around $36k.  

Sources tells us the neighbor offered to pay Whitney something, but it's unclear how much.

We spoke with the neighbor, who had no comment. We also reached out to Whitney, but so far no word back.
