Nurse!

"American Idol" singer Michael Johns died from an enlarged heart, but a "fatty liver" contributed to his death ... this according to the Coroner's report.

The 35-year-old singer died suddenly Aug. 1 after his leg became swollen and bruised ... reportedly from a sprained ankle. Family sources claimed the injury had triggered a blood clot, but his best friend claimed the singer drank himself to death.

The Orange County Coroner's report concludes Johns died of natural causes -- the result of a disease called dilated cardiomyopathy, a condition that inhibits the flow of blood to the body. The disease caused his heart to enlarge.

As for the "fatty liver" ... it can be caused by excessive alcohol intake, but there are other causes as well. Law enforcement told us ... Johns often drank to excess and did so hours before he died.

Monday night's alright for fighting too -- unless you're the dude whose foot was damn near torn from his body in a brutal West Hollywood street brawl last night.

The fight went down outside DBA Nightclub around 2 AM ... when no fewer than 3 guys surrounded another guy in the middle of Santa Monica Boulevard and unleashed holy hell -- repeatedly kicking and punching the victim.

When he ends up on all fours ... things really get gruesome, because he gets rolled ... and his ankle fully SNAPS IN TWO!!! It's unclear what started the fight --- but it's obvious from the video what ends it.

Solange Knowles sure looked great at her New Orleans wedding, but some sort of severe food allergy made her break out in HIVES after the reception.

And just when ya think she can't catch a break -- her ole elevator mates, Beyoncé and Jay Z, show up to save the day!

Solange Knowles looked great during her wedding, but after the reception she broke out in hives ... and by process of elimination, she's either allergic to shrimp, or Jay Z.

It doesn't seem to be a case of nerves ... Beyonce's sister's face appeared smooth and radiant in the wedding photos ... but after the reception -- when she got in a car with Jigga -- all hell broke loose on her face.

According to our sources, Solange suffered some kind of food allergy, though she isn't sure what it was from. We're told the hives were gone in a matter of minutes.

Solange got hitched in New Orleans Sunday -- she married music video director Alan Ferguson.

Rough.

Richard Simmons' close friends are now mad, in addition to being extremely concerned for his welfare ... because they believe his spokesperson is shoveling crap with the story that Richard's OK.

The spokesman told the NY Daily News ... Richard is "sad" but not clinically depressed, a shut-in or a recluse.

Now extremely close friends of Richard are pissed ... saying Richard's people are not leveling. For a variety of reasons, they believe something dire has happened.

-- The last contact any of his closest friends had with him is March 10.
-- The mother of an extremely close, long-time friend died a few months back, and Richard never contacted her, which is completely out of character.
-- Richard was close with Joan Rivers and, as one friend put it, "There is no way he wouldn't have gone to her funeral if he was OK."
-- He has abandoned his exercise studio, where he was a fixture. He hasn't been there in months, and everyone there says they have no idea why.

As we reported ... one of Richard's key people told us a looming knee replacement sent him into a massive depression ... exacerbated by the death of his beloved dog. But the close friends say they don't believe knee surgery or the dog would cause Richard to cut himself off from the outside world.

As one friend said ... "If Richard is really OK and is aware people are extremely concerned about him, he'd pick up the phone and tell them to relax. But he hasn't, and we're worried sick."

Glen A. Larson -- who created the hit shows "Magnum P.I.", "Knight Rider" and "Quincy M.E." -- has died from esophageal cancer at the age of 77.

The incredibly successful writer died Friday night at UCLA Medical Center ... according to his son James.

Larson was one of the most prolific producers of the '70s and '80s ... creating a string of iconic hit shows -- including "Battlestar Galactica," "The Fall Guy," "B.J. and the Bear," and "Buck Rogers in the 25th Century."

He also wrote the original "Six Million Dollar Man" pilot and TV movies.

In case you're wondering ... Quincy, Magnum, Rider and Fall Guy alone account for 513 hours of television -- as well as 21 combined seasons from 1976-88.

Safe to say this guy helped define an entire generation of TV watchers.

Iggy Azalea has no tolerance for pain ... 'cause she claims she "smashed" herself in the face while dunking a basketball ... despite strong video evidence to the contrary.

Iggy was hoopin' around with her BF Nick Young on Friday when she decided to test out her dunk skills.

She went up. She threw down. Ball sorta love-tapped her in the face.

So, of course, she immediately went to Twitter and injected faux drama ...

"Somehow while trying to dunk a damn ball i smashed myself in the face. i won't quit my day job anytime soon. lol."

Dierks Bentley sings about being drunk on a plane, but now the country superstar is also an expert on vomiting on a stage ... thanks to a drunk fan -- and the footage is disgustingly awesome!!

Dierks was performing at the Hershey Giant Center in Pennsylvania last night and brought two fans on stage to sing along to "Drunk On a Plane."

The truly gnarly part of this video is that ... we've all been right where this chick was -- just not in front of thousands of people. A rep for Dierks tells us he felt really bad for the fan.

Bret Michaels is back on stage, and somehow lovin' it ... just 2 days after going under the knife to have 2 stents ripped out of his body.

If Bret was in pain, he masked it well while he performed in Jacksonville Thursday night. Pretty amazing ... the guy's been in and out of 6 different hospitals over the last couple weeks to deal with complications from his diabetes.

Normally, stent removal is incredibly debilitating ... it can take several weeks to recover.

But Brett's pure bad ass. He's got 6 more shows over the next 2 weeks.

Alfonso Ribeiro -- the front-runner on "Dancing with the Stars" -- may have to pull out of the competition days before the semifinals ... and it's all because of The Carlton Dance.

Our DWTS sources say Ribeiro injured his back during rehearsal Wednesday night as he tried to overcompensate for a groin injury which he suffered on the show, performing his signature move.

The back injury is bad -- he's having trouble even walking. Alfonso skipped rehearsals Thursday so he could get an MRI.

Doctors are telling him the next 48 hours are critical, but they say there's a real chance he can't dance.

"Real World/Road Rules Challenge" star Diem Brown has died after a long battle with cancer.

Diem -- who found out she had ovarian cancer 3 weeks before her first appearance on MTV in 2006 -- was reportedly surrounded by family this week in a New York hospital as her condition worsened.

Back in August, the reality star collapsed on set while filming "The Challenge" ... then announced she had been diagnosed with stomach and colon cancer. It eventually spread to her liver and lymph nodes as well.

Diem founded MedGift ... a support registry for other people battling illness.

One of her most inspirational moments on MTV came when she took off a wig to reveal her hair loss due to chemotherapy.

Diem was 34.

The death of Richard Simmons' dog played an important part in the depression that has turned him into a shut-in ... a dog he considered his child.

TMZ broke the story ... Richard hasn't been seen in public for almost 11 months ... and the trigger was a looming knee replacement which shut Richard down professionally and socially.

Sources close to Richard tell us his Dalmatian Hattie died within days of his last public sighting back in January. Richard took the dog with him when he was out and about in L.A. and would often brag about her in his exercise classes.

Richard -- who never had kids of his own -- treated Hattie like a child. Richard had several Dalmatians and Hattie was the last survivor.

Richard had a deep bond with the dog, who was 17 when she died ... and it destroyed him.

The knee was the trigger, but the dog was the emotional tug that contributed to Richard's life paralysis.

2:40 P.M. PST -- Richard just posted a message on his Facebook page:

Something is seriously wrong with Richard Simmons ... he disappeared for almost the entire year ... and we're told there's a physical problem that has led to debilitating depression.

Simmons was last photographed in public January 11th at a charity event. TMZ got video of Richard later that evening, but that's the last time anyone has seen him in public.

Various people who are extremely close to Richard tell TMZ ... he has gone radio silent with them, he does not accept or return phone calls, and he has his housekeeper turn people away when they come to visit him.

Richard has not shown up at his famed studio, Slimmons in Beverly Hills, for months. Simmons was a fixture there, regularly teaching classes. The staff offers no explanation for his prolonged absence.

A source extremely close to Richard -- one of the few people with whom he is in contact -- tells TMZ the fitness guru is in a massive state of depression over a bum knee. He says doctors told Richard he needs a left knee replacement and if he doesn't get one he will never be able to exercise again.

The source says Richard is terrified of the surgery and has put it off all year. He had a right knee replacement 4 years ago and he put off that surgery for nearly a decade ... he was that frightened.

We're told Richard has tried stem cell and red blood platelet therapy -- like Kobe Bryant -- but it failed.

We're told he's paralyzed with fear and depression, which has made him a shut in for 2014.

Other friends and business associates tell TMZ they don't believe this is just a knee problem ... they think it's more serious.

We left a message for Richard, but he did not return our calls.

John Wayne Bobbitt got cut off again ... and this time he suffered a broken neck.

JWB was driving to his brother's house in Buffalo Tuesday when another car ran a red light and T-boned his jeep. John suffered a broken vertebrae in his neck and a slipped disk.

We're told he should fully recover.

John notoriously beat his wife Lorena -- so she claimed -- and she got revenge in 1993 by cutting his penis off. Doctors reattached his schlong and John went on to do porn and screw scores of chicks.

We're assuming his penis is in fair condition.

Amanda Bynes is not telling the truth when she says her parents aren't allowing her to have a roof over her head, because we've learned she's had a place all along ... she just doesn't like the location.

Sources connected with the Bynes family tell us ... Amanda's parents got her a room in a Glendale hotel immediately after she was released from the psychiatric facility.

Amanda does NOT want to stay in Glendale, but her parents were firm ... they will not get her a place anywhere near Hollywood or West Hollywood, because they think it spells nothing but trouble and where leeches glom onto her.

Our sources say Amanda's parents have told her if she wants a different area they'll find her a place, as long as it's not Hollywood or WeHo. But that's where Amanda wants to be and that's why she's been mooching off friends and crashing at their places.

Bret Michaels is in the hospital again, after a series of serious medical emergencies during his tour.

The Poison lead singer postponed a concert in Champaign, IL last week so he could undergo kidney surgery to correct a problem triggered by his diabetes.

He sucked it up and made his Friday date in Memphis and Saturday's show in Knoxville ... but things got ugly quick.

The stents started bleeding out while he was on his tour bus ... forcing him back to the ER where stents were removed.

This isn't the first time Bret's diabetes have acted up on tour ... he was rushed off stage for a similar problem back in May after performing just 3 songs.

We're told Bret's been admitted to 6 different hospitals over the last 2 weeks -- yet he didn't cancel a single show.

Now that's something to believe in.
