Demi Lovato didn't "suffer an overdose" -- she caused it -- so says a famed interventionist.

Jeff VanVonderen -- who appeared on the A&E show "Intervention" -- says Demi's alarming relapse resulted from choosing to stop using the tools that kept her sober.

It's tough love for sure, but Jeff says it's all in Demi's hands. The good news ... he says she was able to use the tools to stay clean for 6 years, so she can do it again if she puts her mind to it.

TMZ broke the story ... Demi was in dire straits when she OD'd earlier this week in her Hollywood Hills home. Paramedics found her unconscious and, when she regained consciousness, she refused to tell EMTs what drug caused the 911 emergency.

Demi Lovato showed no real signs of trouble -- at least visually -- hours before she overdosed.

This video was shot Monday night at Saddle Ranch on the Sunset Strip, where Demi and others celebrated the birthday of Dani Vitale ... one of Demi's backup dancers.

She just kinda stares at the birthday cake, so it's hard to know what state she was in. Daily Mail first reported on the vid.

As TMZ reported, people who observed Demi at Saddle Ranch saw no real signs she was under the influence of drugs ... she was laughing and smiling during the party, according to those present.

12:00 PM PT -- Michelle just shared a message of gratitude for all the love and support she's received the past 2 weeks. She included words of encouragement for those battling with depression like herself ... and even tossed in a joke and a brag about Beyonce's mom cooking her a huge meal.

Beyonce and Kelly Rowland immediately dropped what they were doing when they heard Michelle Williams checked into a mental health facility to treat her depression ... and, like good, longtime friends, they reached out to offer their support.

Sources close to Destiny's Child tell TMZ ... Bey and Kelly were incredibly sad after learning Michelle had been struggling with depression and was having such a hard time dealing with it she sought professional help.

We're told both Beyonce and Kelly offered many words of encouragement, expressing their love for her and letting her know -- if Michelle needed anything, they were there to help.

Wilmer Valderrama looked worried sick when he visited Demi Lovato at the hospital.

Wilmer hit up Cedars-Sinai in L.A. Thursday afternoon and stayed with her for about 5 hours. He also visited Demi Wednesday ... a day after she was rushed to the hospital for an overdose.

The 38-year-old actor and 25-year-old singer broke up in June 2016 after dating for about 6 years ... but they remained close, so it's no surprise he rushed to Demi's side when she landed in the hospital.

Demi Lovato could have died Tuesday from her overdose -- it was that serious -- sources connected to the singer tell TMZ.

We're told the 911 call did not come a minute too soon, because Demi was in dire straits. "She could have died," said a source with firsthand knowledge. Demi was unconscious when she was discovered at around 11:30 AM and the 911 call was placed.

TMZ broke the story ... Demi received Narcan to counter the effects of opioids. As we reported, Demi and those who were at the house refused to disclose the drug or drugs that caused her to OD.

TMZ obtained the 911 call ... in which the person at Demi's home asked the dispatcher if the emergency vehicles could come without sirens -- presumably because they wanted to keep the OD on the down-low. The dispatcher informed the caller the sirens would stay on.

Demi remains hospitalized. We're told those around her want her to enter a rehab facility when she's released, but ultimately the decision is squarely hers.

Demi Lovato's friends wanted to keep her OD on the DL ... asking paramedics to come to her house without sirens.

In the 911 call from Lovato's house -- obtained by TMZ -- the caller remains calm while taking orders from the dispatcher. As the ambulance approached, the dispatcher let the caller know they'd soon hear sirens to which the caller responded, requesting they be shut off ... seemingly to keep the situation private from neighbors. However, the dispatcher says that's just not possible.

We broke the story ... Demi was rushed to an L.A. hospital after suffering an overdose, which law enforcement believed was from heroin. However, a source close to the singer said it wasn't heroin, but refused to divulge the source of the OD.

Demi's emergency came after an all-night party that started with a birthday celebration for one of her backup dancers at Saddle Ranch in WeHo.

As we reported ... Lovato had been struggling with drugs for weeks, even before last month's public confession of a relapse on her song, "Sober."

Check out the initial dispatch audio (below). You hear the dispatcher for the L.A. Fire Department calling LAPD and saying, "I thought maybe you guys better go on something like this." It's unclear if he's saying the LAPD should go out because Demi is a celebrity, or because of a drug overdose. The call is redacted, so we don't know if Demi's name or the OD was mentioned.

Demi Lovato was found unconscious in her bed after a long night of partying, and a panicked assistant called 911 ... TMZ has learned.

Sources familiar with the matter tell us ... Demi had invited some of her friends back to her house early Tuesday morning after a party on the Sunset Strip to celebrate the birthday of one of her backup dancers.

It's unclear how long the party lasted, but Demi went to sleep and, at around 11 AM Tuesday one of her assistants became concerned because Demi hadn't come out of her bedroom. The assistant entered the room and found Demi unresponsive, tried waking her and when she couldn't ... she called 911.

When paramedics arrived Demi was still unconscious. Someone at the home told paramedics Demi had been partying all night, and we're told EMTs then determined they were dealing with an overdose. They quickly administered Narcan -- an antidote to opioid ODs.

Demi Lovato's team tried to stage an intervention and get her help for her drug addiction, but the singer blew them off ... TMZ has learned.

Sources close to Demi tell us members of her team noticed she was in a bad place a few weeks ago, and even confronted her about it. We're told they offered assistance to get her back to sobriety. The plan was to urge her into a rehab program.

We're told the intervention attempt was not successful -- Demi refused and continued to party, instead. Other sources tell us she tried to make it seem like everything was okay, but her struggle became obvious shortly before Tuesday's overdose.

There's also this -- Lovato and her longtime manager, Phil McIntyre, parted ways a couple months ago. Although neither has said why they broke off their professional relationship ... we're told Phil had a hand in the intervention efforts.

Bishop Michael Curry -- the man who told Prince Harry and Meghan "love is the way" -- is now dealing with a cancer diagnosis.

Bishop Curry says he found out a few months ago, during an annual exam, he has prostate cancer ... and he's now decided on a course of treatment.

He'll undergo surgery next week to remove his prostate gland, and anticipates taking 4-6 weeks to recuperate ... before getting back to work. Curry says, "I am happy to say that the prognosis looks very good and quite positive."

Isaiah Thomas tells TMZ Sports ... he's fired up to show the NBA he's healed up and back to the superstar he was -- and wants to prove in 2018 that he's worthy of a max contract.

Remember, the 2-time All-Star just signed a veteran's minimum, 1-year, $2 million contract with the Denver Nuggets ... and when we saw him at LAX, he explained why he took the deal.

"The goal is just to show that I'm healthy and I'm the same player I was before," Thomas said ... "I just need one year."

The 29-year-old has been battling hip problems since the 2017 playoffs -- but underwent surgery back in March and recently said he's feeling better than ever.

But, this 2018-19 season isn't all about him ... IT says he's ready to take his squad to new heights.

"We'll make the playoffs ... and then we'll go from there."

Thomas also had some comments about his old team, the Boston Celtics -- which traded him after a remarkable playoff run in 2017.

Demi Lovato's upcoming concert North of the border has been canceled.

Demi was scheduled to perform Sunday, July 29 at Echo Beach in Canada at the RBCxMusic benefit for Kids Help Phone with special guest Jason Mraz, but in light of her recent OD ... it's not happening.

A rep from Live Nation Canada tells us tickets will be automatically refunded.

Demi Lovato's overdose after an all-night party has been a sad shock to her fans and friends ... including her old friend, Justin Bieber.

JB was out in L.A. Wednesday when a photog asked him if he's spoken to Demi yet ... he says he hasn't, but he's sending out prayers to her and her family. He also calls the situation "terrible" and "very sad."

The Demi news apparently came as a stunner to Justin too ... because he says he thought she was sober.

We broke the story ... Lovato had actually been struggling with drugs weeks before her OD, even before she confessed last month she had relapsed in her song "Sober."

Justin must have missed that revelation but, as we know ... he's been busy with some major stuff going on in his own life.

Dennis Quaid took a puff on a plane, and broke both the airline's policy and a fellow passenger's peace of mind ... according to a new lawsuit.

A guy named Karl Larsen is trying to drag Dennis to small claims court in L.A., claiming the veteran actor smoked an electronic cigarette next to him in first class on an Air Canada flight from Toronto to L.A. when he shouldn't have ... 2 whole years ago in July.

According to the complaint -- obtained by TMZ -- Larsen says Quaid owes him the cost of a plane ticket for ... well, reasons that are unclear. He doesn't spell out why Quaid should pay him, but he does make note that he's cutting the guy a break -- only looking to be reimbursed the price of a biz class seat (not first class) from TOR to LAX ... at just $3,829.

For the record, Air Canada has a zero-tolerance policy on e-cigarettes on board. Then again ... this thing might be much ado aboot nothin' when it comes right down to it.

We've reached out to Dennis' camp for comment ... so far, no word back.

Genie Bouchard injured her groin last weekend ... but she clearly didn't hurt her butt -- 'cause the tennis star was shakin' it all over the place in Morocco on Wednesday!!

The 24-year-old cruised over to Africa after an injury cut her run in the Swiss Open short ... and she looked no worse for wear gettin' some rehab work in by her luxury hotel's pool.

In a barely-there neon green and hot pink bikini ... Genie made sure to get a couple sets of champagne sippin' and booty poppin' to get right.

Yeah ... we think she'll make a full recovery.

BTW -- Genie's getting pretty good at this whole bikini thing ... she slayed the SI Swimsuit shoot this year.

Eat your heart out, Super Bowl bet guy.

Rep. Sean Patrick Maloney just learned that sometimes you gotta fight the good fight to get what you want -- and in this case he (and his female staffers) got it ... 500 boxes of tampons, and counting!!!

We got the New York Congressman Tuesday at his office in D.C., and he says folks across the country heard his message on TMZ loud and clear ... that the GOP had told him he couldn't use public funds to buy feminine hygiene products for his staff.

Maloney tells us tampons have been pouring in ever since he got on TMZ, and he's now dishing them out to anyone and everyone in Congress who wants some. Don't panic -- he's got plenty to go around.

Michelle Williams of Destiny's Child had a pep in her step the day after her birthday ... and not long after she received treatment at a mental health facility.

We got Michelle and her fiance, Chad Johnson, out Tuesday night and she looks great. It's the first time we've seen her out since we broke the story last week she checked herself into a mental health facility for depression.

Michelle turned 38 Monday and our camera guy wasn't the only one to wish her HBD. Kelly Rowland also gave her a shout-out on Twitter, but not before Michelle posted on Instagram a few days earlier, "I feel the [love]. I just wanted to let you guys know I'm better!"
