Delonte West was discombobulated on the streets of Houston last month because he was on the wrong medication and left his treatment facility while hallucinating ... but now he's on the road to recovery.

Charlie Sheen wanted everyone to know he's HIV free -- at least that's what his wardrobe seemed to be screaming at Elton John's AIDS Foundation party.

Charlie's t-shirt at Elton's annual Oscar event read, "Stay positively negative." Sheen has maintained there's no trace of HIV in his blood ... ever since announcing last November he'd contracted the virus.

The event raised more than $6 million for AIDS research, and if some thought Sheen's clothing selection was in questionable taste -- Elton and his husband David Furnish didn't seem to mind.

A contestant on "Survivor: Kaoh Rong" failed to outwit, outplay and outlast the feds ... because she pled guilty to felonies for falsifying Hurricane Katrina water test results ... TMZ has learned.

Debbie Wanner, a 49-year-old chemist from Reading, PA, was arrested in 2010 and charged with 3 counts of falsifying test results from Hurricane Katrina water samples.

Wanner worked for a private lab that did testing for various Pennsylvania counties and private companies. Her company was hired to ensure water met various environmental standards.

According to legal docs, Wanner took on clients when she knew her company did not have the proper equipment to provide accurate results. The criminal complaint alleges she falsified water test results.

Wanner pled guilty to 3 felonies for falsifying results. She was placed on 1 year probation.

It's interesting timing ... she's on the show in the middle of the Flint water crisis.

Debbie's strutting her expertise on 'Survivor' on all things water ... if they only knew.

Fetty Wap is back in the saddle again -- just 5 months after that motorcycle crash that broke his left leg in 3 places he's rolling with some serious riders.

Sources close to the situation tell TMZ, Fetty is currently honing his skills with the Go Hard Boyz -- a Harlem motorcycle group -- for a project to help benefit the inner city.

For now, it looks like the "Trap Queen" rapper is on 4 wheels instead of 2, but he already has some sharp moves.

What hernia surgery?!!?

Here's J.J. Watt DUNKING A BASKETBALL ... just 4 days into his "full training" after undergoing groin surgery back in January.

The Houston Texans star was cleared to go back to full strength training earlier this week -- and judging by the video ... it's going well.

Blac Chyna's pissed she's looking like the bad guy after posting a vid of all the food that was stocked in Rob Kardashian's kitchen ... when all she's doing is helping him slim down.

We're told she's upset because people think she was insulting Kris Jenner, who was presumably behind the quinoa, gourmet crackers, I Can't Believe It's Not Butter ... and other healthy items purchased. Remember, he's diabetic.

Sources close to Rob and Chyna tell us they have a strict no carb rule which has been instrumental in helping Rob shed lbs. We're told Chyna was just busting on the carb-filled selections in the cabinet -- and has zero beef with Rob's mom.

Besides, we're told Chyna doesn't even buy that Kris picked out the food. As one source put it, "When's the last time you saw Kris Jenner inside a grocery store?"

Jets WR Brandon Marshall says it's obvious former NBA star Delonte West needs help ... and he believes it's the duty of the NBA to reach out and give him the treatment he needs.

TMZ Sports broke the story ... West was recently seen at a Houston fast food joint in the middle of the night, without shoes, looking pretty disheveled.

Marshall -- who's been very vocal about overcoming his own mental health issues -- was at LAX when we asked about West's seemingly dire situation ... and who could help.

Check out the clip -- Brandon says he definitely thinks Delonte needs a helping hand ... and that the NBA could -- and should -- do their part to reach out to guys having tough times.

Blac Chyna went ham on Kris Jenner and her family for daring to help stock Rob Kardashian's new kitchen with healthy food.

Check out the video ... Chyna scoffs at the food choices, including fat free sorbet, I Can't Believe It's Not Butter, wheat tortillas, oatmeal and quinoa. BTW ... there's also pizza crust mix, although it's wheat.

TMZ broke the story ... Kris helped Rob buy a house in the Calabasas community where his sisters live. It seems Chyna's none too happy his family is back in the picture.

Our Kardashian sources tell us they think it's despicable Chyna's making fun of Rob's family for trying to help him beat his diabetes and weight issues.

To Chyna's credit, Rob has lost around 40 lbs on her watch.

Rob made it clear which sides he's picking between Chyna and his fam with a very descripitive IG post late Tuesday night ...

"Teen Mom 2" star Jenelle Evans is desperate to find out why she keeps landing in the hospital ... and she's flown cross-country to figure out what's wrong with her.

We got Jenelle right after she arrived at LAX. She told us she's meeting with specialists to figure out why she's having joint pains and severe hot flashes at just 24 years old.

We asked if she'd been stressed while shooting a new season of 'Teen Mom' and Jenelle's response is interesting. At this point, there's no guarantee she'll stay on the show.

MMA fighter Dada 5000 is doing MUCH better after a frightening health scare following his fight with Kimbo Slice at Bellator 149 this past weekend ... so says Dada's rep.

We spoke with Mike Vazquez -- who says he was with Dada in the hospital following the fight -- and he tells us, "Dada is recovering well. On his feet and moving around. Back to his usual self."

"He should be out [of the hospital] by the end of the week and can personally address [then]."

Rob Kardashian is sticking to a strict diet -- no fast food, regular workouts and lots of Blac Chyna ... and friends think it's already helped him shed about 40 lbs.

We're told Rob's also cut out red meats and carbs while hitting the gym 5 times a week with a trainer ... plus additional workouts with Chyna.

We're told the couple made a "no cheat days" vow, and they're motivating each other to stick to it.

It's hard to say the program isn't working, based on recent pics. Some home cookin' from Blac Chyna doesn't hurt either ...

The Gronk cruise will be ONE GRONK DOWN ... 'cause Rob's brother Dan tells TMZ Sports he has to bail on the party boat because his wife is pregnant and they can't risk getting the Zika virus.

The cruise (which leaves Friday from Miami) has been the talk of the family for months -- in fact, Dan says he and wife Brittany had timed out their pregnancy (she's not due until June) so they could both go along for the ride.

But with the Zika virus spreading to the Caribbean -- close to where the cruise will sail -- Dan and his wife have decided it's too big of a risk ... and had to tap out.

"My wife can't go because she's pregnant and I can't go because it can be transmitted [sexually]," Dan says.

FYI -- medical research suggests Zika can cause serious birth defects in unborn children.

"I'm really disappointed. I was pumped for the cruise."

As for the rest of the Gronks -- "My brothers are all down in Florida ... they've already been going nonstop!"

"Mob Wives" star Angela "Big Ang" Raiola has died after a battle with stage 4 cancer ... TMZ has learned.

Ang was surrounded by family members early Thursday at a Manhattan hospital when she passed away. She was first diagnosed with throat cancer in April when doctors discovered a tumor in her throat and it was removed shortly after.

Her rep released a statement saying Ang passed at 3:01 AM ET, and TMZ has also confirmed it with family members. The rep added ... Ang's fans "were some of the most special people in her world, and she loved you immensely. Thank you for your love, prayers, and unconditional support of Angela right to the very end."

Hours earlier, Ang's team had to clear up false reports she died Wednesday evening.

Ang learned her cancer had returned in December and spread to her brain and lungs.

Raiola is survived by her two kids, Raquel and Anthony, and has six grandkids.

She was 55 years old.

R.I.P.

Rihanna was screaming and hysterical before she bailed on the Grammys, but there are conflicting stories about what triggered her outburst.

Sources connected with the show and several sources who were not connected but present at the show tell TMZ ... the singer was loudly expressing displeasure over her rehearsal. They say she was loud and upset and, as we first reported, bailed on the event.

Rihanna's people say she had a medical issue ... bronchitis that was so bad she could not perform and that's why she left. Sources close to RiRi tell us she was too upset to stay and watch the show.

It's interesting ... Rihanna sang flawlessly two nights before the Grammys at a Lionel Richie charity event. Several sources say her voice was also great at the Grammys rehearsal.

Big Ang is fighting stage 4 cancer all on her own, and wants it that way -- she got emotional about ending her marriage during an appearance on 'Dr. Oz.'

The "Mob Wives" star revealed why she was splitting from Neil Murphy, husband of 6 years, and made it clear "it's too late" to repair the relationship.

As TMZ first reported ... Ang has been experiencing severe pain lately as she battles cancer, and her family is trying alternative treatments to manage the pain.

On Tuesday's episode of 'Oz,' she also said doctors have given her a 30 percent chance of survival.

Here's LSU running back Leonard Fournette busting out a set of 405 POUND squats like it's nothing.

Last year, Leonard said he could max out at 605 lbs ... and the way he knocks out 405, it makes you wonder if that number has gone up even more.

For comparison, here's Alabama running back Derrick Henry busting out 1 rep of 500 pounds last year.
