Celebrity Rehab

The actor's rep has released a statement saying, "Seann William Scott has voluntarily admitted himself for proactive treatment to address health and personal issues."

The rep continues, "He appreciates the support of his many fans at this time."

It's unclear what "condition" Tareq is referring to -- but Michaele has said in the past that she suffers from multiple sclerosis.

Tareq and his lawyers have issued a statement saying, "[Michaele] was fired due to her health condition which is a violation of the Americans with Disabilities Act."

Team Salahi says they will announce more details about their gripe later today.

Law enforcement sources tell us the call came in to Pasadena PD around 5:30PM ... Bai Ling was on the roof and there was concern for her safety.

Bai Ling is on the new season of "Celebrity Rehab" ... which, coincidentally, is just starting to shoot.

Before officers could respond ... we're told Bai came in from the roof -- and since there were medical professionals there to handle the situation there was no need for the police.

Starr appeared on the third season of "Celebrity Rehab" back in 2009 -- and was arrested last month for felony possession of a controlled substance. Salt Lake City cops say he had 6 Xanax pills and 6 Opana (painkiller) pills when he was busted.

Starr was 44 years old.

Mike's dad tells TMZ, "It's a terrible shock and tragedy."

UPDATE: Police tell us Starr's body was found in a Salt Lake City home today. Cops say they were called to the house at 1:42PM.

Sources on the set tell us Michaele was asked to leave because she has "no addiction," and thus had "no reason to be there."

Over the weekend we got Tareq Salahi out in Los Angeles who told us that Michaele's only addiction was "probably to chocolate."

In the 11-page letter, obtained from sources connected to Charlie, Warner Bros. states, "Your client has been engaged in dangerously self-destructive conduct and appears to be very ill."

The letter then goes on to describe Charlie's hijinks, including trashing the Plaza Hotel in NYC, coke binges, on-set failures because of drug fatigue, and diatribes against "Two and a Half Men" creator Chuck Lorre.

The letter also notes that Charlie derailed production when he went into rehab, and then he fired his sobriety coach. In fact, Warner Bros. claims it was so concerned about Charlie's well-being, "Warner Bros. had an airplane waiting" to take him to a treatment facility ... but Charlie would have none of it.

As for why Charlie got fired, the letter says there is a clause in his contract saying they can fire a performer who commits "a felony offense involving moral turpitude."

The letter says, "There is ample evidence supporting Warner Bros. reasonable good faith opinion that Mr. Sheen has committed felony offenses involving moral turpitude (including but not limited to furnishing of cocaine to others as part of the self-destructive lifestyle he has described publicly) that have 'interfere[d] with his ability to fully and completely render all material services required' under the agreement."

In short, that's why Charlie was fired.

Charlie's lawyer, Marty Singer, has demanded Warner Bros. pay Charlie for the eight canceled episodes -- or else.

One of the guys behind "Thunder from Down Under" -- a famous male strip show in Sin City -- tells TMZ producers saw the ridiculously jacked pictures of Jeremy that TMZ posted on Friday ... and think he'd make a perfect addition to their line-up.

We're told "Thunder" wants to get their hands on Jeremy as soon as "Celebrity Rehab" wraps up -- despite the fact that he ain't actually Australian ... which is kinda their thing.

But there's one problem -- Jeremy plans to quit injecting himself with hormones now that he's in rehab ... so he might not look exactly the same by the time he gets out. Oh well.

Adler appeared on season two of "Rehab" and the first season of the spin-off show "Sober House" back in late 2008, early 2009. Adler then went on to stints in real rehab centers after being ordered to by a judge as part of a DUI bust.

Tareq is living the bachelor's life in West Hollywood while his wife Michaele is off shooting "Rehab" as well. We tried to ask Tareq what Michaele's "addiction" was -- and all he did was explain she has multiple sclerosis.

We're told Jeremy -- who played Hobie on the show -- got into fitness a few years back as a way to help kick his meth addiction, and it worked ... but what used to be a healthy hobby spiraled out of control ... and now he fears for his life.

Sources close to Jeremy tell us, he's not only addicted to the gym -- he can't stop injecting HGH (Human Growth Hormone) and testosterone (an anabolic steroid).

We're told Jeremy even injects himself with vitamin B12 -- a procedure typically done by medical professionals -- and loads up on countless other supplements he fears are destroying his body.

We're told Lohan is saying she's most upset that her dad, Michael Lohan, began taping the show without ever giving her a heads up.

Lohan is also adamant she will NEVER make an appearance on the show.

Lindsay also wants to know how much Michael is getting paid for the gig -- because she wants to make sure her dad kicks over some of the cash to Dina ... since "he should be paying his child support for Ali and Cody."

FYI -- "Celebrity Rehab" had been gunning for Lindsay to star on the show in the past ... but it never came to be.

Sources connected to the production tell us ... Dr. Drew will have one hell of a cast for Season 5 ... including:

Dwight "Doc" Gooden ...................Former NY Mets pitcher
Tareq AND Michaele Salahi ........ Alleged WH crashers and "Real Housewives of D.C."
Bai Ling ............................................ Actress?
Michael Lohan ............................... Lindsay's dad
Jeremy Jackson .......................... aka Hobie from "Baywatch"

Were you expecting Charlie Sheen?

Dina landed at LAX this afternoon with her other children: Ali, Michael Jr., and Cody. Lindsay hasn't seen them since she got out of rehab, so she's overdue for a little QT with the fam.

Starr was arrested and booked on suspicion of felony possession of a controlled substance early Thursday ... according to Salt Lake City PD arrest documents.

Starr was a patient on the third season of "Celebrity Rehab" back in 2009. He also appeared on the most recent season as an example of a celeb who got clean after appearing on the show.

Sources close to Lohan tell us ... Lindsay is "worried" about Sheen because his most recent bender shows "obvious signs of addiction" ... something Lindsay knows about all too well.

But after Sheen decided to check himself into a treatment center Friday afternoon, Lohan is confident he can get his life back together ... if he commits himself to sobriety.

Sources close to Demi tell us ... the actress wants to focus on getting back into her "regular routine" and spend time with her family and close friends.

We're told Demi will continue to seek treatment for her issues while in L.A.

As TMZ first reported, Demi went to the treatment center after punching a backup dancer on a tour with the Jonas Brothers -- and claims she sought help for "emotional and physical issues."

UPDATE: Demi was spotted out this afternoon in Santa Monica.
