Celebrity Rehab

"That 70s Show" actress Lisa Robin Kelly died from "multiple drug intoxication" ... and her death certificate reveals .... she took an overdose of drugs by mouth.

The L.A. County Coroner's report -- obtained by TMZ -- confirms what we previously reported ... that Kelly's death was an accidental overdose.

Kelly -- who played Eric Forman's older sister on the show -- died August 15th at an alcohol rehab facility in L.A. County.

It's unclear how she obtained drugs in the rehab facility.

Ke$ha has gone to rehab for an eating disorder ... TMZ has learned.

Sources connected to the singer tell TMZ ... she's at Timberline Knolls near Chicago, the same place Demi Lovato went for her issues.

We're told the singer -- who's a vegetarian -- was admitted early this morning.

Ke$ha tells TMZ, "I'm a crusader for being yourself and loving yourself, but I've found it hard to practice. I'll be unavailable for the next 30 days, seeking treatment for my eating disorder ... to learn to love myself again, exactly as I am."

In Ke$ha's recent music video with Pitbull -- for the song, "Timber" -- she looks discernibly thinner.

"That '70s Show" actress Lisa Robin Kelly died from "multiple drug intoxication" ... and the L.A. County Coroner tells TMZ her death has been ruled an accidental overdose.

TMZ broke the story ... Kelly -- who played Eric Forman's older sister on the show -- died August 15th at an alcohol rehab facility in L.A. County.

An autopsy performed immediately after she died failed to identify the exact cause of death -- the coroner had to wait until the toxicology results were in.

The coroner did not identify which drugs were in her system.

Just days before her death, Kelly had been hospitalized with an alarmingly high .34 blood alcohol level ... a level that can sometimes lead to death.

The Coroner's full report will be released within 2 weeks.

Paris Jackson looked healthy and happy vacationing with her mom in Hawaii ... but MJ's daughter still has a long road ahead of her -- we're told the treatment will last years.

Debbie Rowe and Paris mugged for the camera during the trip ... as you know, Rowe lost contact with Paris after she divorced Michael Jackson, but the 2 reconnected a little over a year ago and are now extremely tight. Rowe speaks constantly with Paris -- who is at a boarding school in Utah.

As for Paris' treatment ... our sources say she's riddled with so many problems she's almost certainly spending several years at the facility ... where she is getting intensive counseling.

Zac Efron has taken a page out of Alec Baldwin's playbook ... when something bad happens, turn it into a joke and people will laugh.

That's exactly what Zac is doing -- without saying a word in a new video that makes fun of how he broke his jaw last month.

As TMZ previously reported ... Zac claims he slipped in a puddle of water at his Hollywood Hills home. His jaw broke and he gashed his face.

As you know .... Zac has been to rehab twice this year for cocaine abuse.

Chris Brown was all smiles during his day away from lockdown anger management rehab ... pitching in at a charity toy drive for XMAS.

Chris didn't misstep -- not even once -- during the event ... where people come with unwrapped toys for underprivileged kids.

Chris Brown better not pull any stunts when he leaves lockdown rehab this weekend to attend a charity event ... because TMZ has learned, if he so much as steps out of line ... the rehab facility will kick him out for good.

TMZ broke the story ... CB obtained permission to attend the 3-hour celebrity toy drive on Melrose Avenue Sunday because the rehab facility -- where he's getting help for anger management -- thought the experience would be good for his treatment.

But sources tell us, the Malibu rehab facility is keeping the singer on an extremely tight leash during the excursion.

We're told Chris only has permission to attend the event from 1pm to 4pm ... as soon as it's over, he has to hightail it back to rehab. The facility is giving him just enough extra time to travel to and from West Hollywood, but that's it. ZERO free time to hang with friends before or after the event.

If he's late to rehab Sunday evening, Chris is out ... which would be real bad ... because rehab's the main reason he's not in jail right now. You'll recall, the judge in his Rihanna beating case revoked his probation, but decided not to toss him in the pokey because he was making good progress in treatment.

Demi Lovato is furious at the producers of "X Factor," grousing that she was blindsided by a skit that mocked her addiction ... TMZ has learned.

Mario Lopez introduced a skit which showed clips of Demi drinking what looked like booze, acting annoying and off center.

Demi is extremely upset because addiction has turned her life upside down. It got so bad, she was living in a sober house for more than a year just to avoid temptation.

You can see her reaction on the show ... at one point it appears she says "That's f**ked up."

Demi's already said she's leaving the show, but now it's pretty clear ... for her it couldn't be soon enough.

We contacted reps for the show ... so far no word back.

Matthew Perry is engaged in a war with a British journalist ... a war that has no end in sight -- and it's all over how the U.K. treats drug and alcohol addicts.

Perry was at LAX yesterday when we brought up his fiery exchange with Peter Hitchens on BBC's "Newsnight" ... in which Hitchens (who believes in stronger punishments for drug users) argued that addiction is nothing more than a "fantasy."

During the show, Hitchens went off on Perry and another guest ... saying, "Well you two believe in this fantasy of addiction, a complete fantasy, in which people lose all power over themselves and become victims of this terrible, frightening disease after which they cannot stop taking drugs. If you really believe that then you would presumably think that the best thing would be they never ever come in contact with those drugs."

Perry was furious ... calling his comments "ludicrous" and explaining, “I'm a drug addict. I'm a person that, if I have a drink, I can't stop. And so it would be following your ideology that I'm choosing to do that.”

Hitchens agreed.

Now that a few days have passed and the two have had a chance to cool down, we asked Perry if there was a chance they could ever be friends.

Perry made it clear ... Hitchens shouldn't ever expect a Christmas card.

Chris Brown will spend Sunday on tragically-hip Melrose Ave. in L.A. ... curious indeed, since he's supposedly in lockdown rehab. But we've learned, the rehab joint gave him a day pass.

Chris won't be shopping in stores that sell overpriced, vintage gadgets. He's a featured celeb at the XMAS toy drive, where people come with unwrapped toys for underprivileged kids.

We're told Brown and his girlfriend Karrueche Tran will be front and center to mingle with everyone.

Chris Brown is in trouble ... again. The judge in the Rihanna beating case has just REVOKED his probation because of the fresh assault charges filed in Washington D.C.

Brown was in court for a progress hearing. The judge felt the criminal complaint in D.C. is enough proof that Chris did NOT obey all laws ... which he's required to do while on probation

The judge did not remand Chris into custody, because hizzoner was impressed by Chris' progress in his anger management rehab. The judge will hold a hearing on the matter in February, and it's possible he could sentence Chris to time in the pokey.

The judge also ordered Chris NOT to use medical marijuana for the time being.

TMZ broke the story ... Brown was popped in Oct. for felony assault -- later reduced to a misdemeanor -- and the L.A. County Probation Dept. launched an investigation.

We just got hold of the progress report (above) -- filed with the court -- from Chris' anger management program. According to the document, Brown participates in a weekly boot camp and successfully completed a 12-hour ropes course "to enhance team-building skills and trust."

The clinical team says Chris has been making progress and has new psychotropic drugs that seem to be working. He's been taken off medical marijuana. The team says his ability to "emotionally regulate himself" has markedly improved.

Chief Keef has been moved from a fancy Malibu rehab facility because the media just can't get enough of him.

Keef's lawyer tells us the rapper is no longer at Promises ... he's been moved to another rehab facility in Southern California because of the "overwhelming media attention" he was getting in Malibu.

We're told Keef -- aka Keith Cozart -- still has about 60 days of court-ordered treatment to go ... as he deals with his weed issues.

Attorney Leah Starkman says since Chief won't be home for Christmas ... home will come to him .... arrangements are being made to fly his family out from Chicago.

Good news dog lovers -- Amanda Bynes' canine (the one she accidentally soaked in gasoline back in July while setting a neighbor's driveway on fire) has been placed in a new home ... far, far away from Amanda and flammables.

Sources close to the Bynes family tell us, Sherbert was taken away from Amanda after she was placed on a 5150 psychiatric hold in the summer.

While she was in rehab, we're told Amanda's parents cared for Sherbert ... but have since given him away to a family friend because Sherbert didn't get along with the Bynes family's other dogs.

Sad for Amanda ... as we reported, the actress desperately loved the dog and begged to see Sherbert while she was getting inpatient treatment for schizophrenia and bipolar disorder.

Safe to say, lil Sherb survived some dark days -- here's that video of Amanda rushing to a nearby liquor store to clean him after the near-charring.

Adam Shankman -- the guy who directed "Hairspray" and several eps of "Glee" -- has reportedly checked into rehab.

Shankman's rep told US Weekly ... "Adam Shankman is currently seeking treatment in a rehabilitation center. His friends and family support him and wish him well on his journey to recovery."

The rep did not say WHY the 49-year-old is in rehab.

Seems Shankman is following his friend Zac Efron's lead -- as we previously reported, Zac sought treatment TWICE earlier this year for cocaine.

Selena Gomez went to rehab ... but NOT for herself.

Selena showed up to provide moral support for her good friend, Demi Lovato ... who has successfully been fighting her addictions for two years.

Demi -- who actually lived in a sober living home for more than a year -- showed up to speak to a recovery group ... something she rarely does, and Selena came along for the ride to support her.

We're told ... Demi spoke to the group for an hour ... telling a pretty inspiring personal survival story.

The "X Factor" judge has publicly acknowledged struggling with anorexia, bulimia and cutting ... stories she recalled in vivid detail. Demi went on to say she wanted to surround herself with positive influences, which is why she chose to live in the facility for an extended period and why she values Selena as a friend.

Props to Selena ... and Demi.

Amanda Bynes is wasting no time trying to rebuild her life after rehab ... and plans to hit the books at a private design school because she wants to become a fashion designer, TMZ has learned.

Sources close to Amanda tell us she's enrolled as a student at FIDM -- the Fashion Institute of Design and Merchandising -- registering under an alias for 2 classes at the Orange County campus.

As we reported ... Amanda was sprung from rehab in Malibu last week and released to her parents' care. She was being treated for bipolar disorder and schizophrenia.

We're told ... the people close to Amanda believe school will help ease her back into society by giving her some sort of structure for her life. She's taking a light class load -- by design -- and will be escorted to and from her classes.

We're also told ... the treatment that began in rehab will continue during the school year ... Amanda will juggle her classes with 4-times-a-week therapy sessions.
