Celebrity Rehab

Sources say Brooke has been receiving ongoing treatment for substance abuse at her home, but it has not prevented her from slipping, and the signs have been noticeable for those who have recently come in contact with her.

Brooke has been in rehab multiple times for drug and alcohol abuse.

UPDATE: Brooke's rep, Elliot Mintz, tells TMZ, "What we are really talking about is not rehab ... Brooke is receiving professional help in the area of stress management."

The 59-year-old singer has a storied history of drug abuse -- we'll see if Dr. Drew Pinsky can help out.

TMZ has learned "Celebrity Rehab" is setting its sights on Liza Minnelli to headline its new season.

As we first reported, the show was put on ice yesterday because it didn't have the star power it needed to launch the season.

We're told the parties have been negotiating but no deal has been struck. Insiders say the figure being negotiated is "in the $500,000 universe."

We spoke with Liza, who says she has "no interest" in doing the show. But we're told negotiations continue.

Minnelli reportedly said in 2004 she went back into rehab for alcohol addiction.

We've previously reported the names of several other new cast members, including Tila Tequila and Jason Wahler.

We're told the show could begin shooting as early as Friday.

It should be easier than finding oil in the Gulf ... but "Celebrity Rehab" has been put on ice because they just can't find a big star with a big problem.

Sources connected with the show tell TMZ producers of "Celeb Rehab" can't fill the roster for the new season, which was supposed to start shooting today.

As we first reported, Tila Tequila and Jason Wahler signed on, but there are still holes in the roster. Most important ... we're told there isn't a big headliner.

Our sources say producers offered Lindsay Lohan $1 million and her own show, but LiLo turned them down. We're thinking a good move on Lindsay's part.

We're told Bizzy - real name Byron McCane -- wants to seek treatment for an addiction to marijuana and alcohol.

As we've previously reported, the producers behind the VH1reality show starring Dr. Drew have been on a mission to lock down a cast -- and fast ... or else the show could be in danger.

Wahler certainly has the prerequisites for the show -- he's been arrested several times in alcohol-related incidents .. like this, this, this, this, and this.

We're told no deal has been signed yet -- but the two sides are getting very close to an agreement.

Tila just took to her blog to say, "I finally admitted to myself that I cannot rely on taking prescription pills everyday for the rest of my life!"

In another classy move, Tila added, "I must not be another Lindsay Lohan" -- but a few paragraphs later, she suggests that LiLo join her on "Celebrity Rehab."

It's unclear what personal demon Tila will try to conquer with the help of Dr. Drew -- but it certainly won't be her addiction to attention.

But there's one major catch -- as we previously reported -- VH1 is having problems finding other "celebrities" to rehabilitate ... and if they don't find a cast quick, the show could be killed.

So far, no word on who else the show has its sights set on.

Michael -- who flew in to LAX last night -- claims he still plans to attend Lindsay's hearing tomorrow ... and will try to beg the judge to order his daughter into rehab.

There is no shortage of celebrities that need rehabilitation -- but the VH1 show "Celebrity Rehab with Dr. Drew" can't get any of them to star on the show next season.

Sources close to the production tell TMZ they have struck out left and right trying to find A, B, or even C-list celebs for the show. As we first reported, they had their eyes on Lindsay Lohan and Heather Locklear, to name a few, but were quickly shot down.

The show was able to get a tentative commitment from a few D and F-listers, but our sources say the network rejected them.

We're told there was a deadline last Friday to lock down the cast, but since they don't have ANYONE signed on ... the deadline was extended to Wednesday.

One thing is clear -- no cast, no show.

As we first reported, Michael Lohan asked the judge in Lindsay's DUI case to send LiLo to inpatient rehab in lieu of sending her to jail for missing alcohol education classes ... and the place Michael suggested to send her is the very pricey Oheka Castle.

Only two problems: First, the castle isn't a rehab facility, it's a lavish hotel and resort where celebs like Kevin Jonas get married.

Second, a rep for Oheka tells TMZ it would cost $10,000 a day to rent the top section of the castle -- the only part that's isolated enough to serve as a rehab getaway.

That's a little steep for Lindsay these days, but Michael claims, "several family members have come forward" to help pay for Lindsay's treatment. He's also hoping the castle's owner will give him a friends and family discount.

X is currently in jail in Arizona for violating his probation. Dr. Drew offered to treat DMX at his rehab clinic in California -- and tape the rapper's progress for the show, of course -- but on Tuesday an Arizona judge shot down X's request to hop the border so he could enroll.

According to a rep for the Maricopa County Superior Court in Arizona, the judge rejected the rapper's petition for one reason -- he's already doing really well in the Arizona court-appointed substance abuse program, which ends early in July.

DMX is the #1 draft pick to appear on the next season of "Celebrity Rehab" -- that is, if the rehab people can somehow find a way to keep him from being locked up.

DMX's attorney, Gary Jenkins, tells TMZ reps for "Rehab" contacted him after X was arrested on Tuesday for allegedly violating his probation by using drugs.

Jenkins says the "Rehab" team is considering sending someone to DMX's next court hearing to speak with the judge -- just like Dr. Drew did with Jessica Sierra from "American Idol" -- to try and get X placed in their care instead of being locked up.

The rapper is currently being held on no bond and is expected back in court March 16.

Corey Haim was approached in the last 10 days by the casting company for "Celebrity Rehab" ... TMZ has learned.

Sources connected with Dr. Drew's show tell us casting producers called Corey. They say he was "extremely defensive and insulted, saying, 'It's the last show I'd ever do.'"

Our sources say the 3-minute conversation ended with Corey saying, "I do not need help."

We're also told the casting producers spoke with Corey's mom last October at an autograph convention, pitching the show.

Brooke Mueller has left her second rehab facility and gone back to live at the family home ... but this time she's brought all the rehab professionals with her ... TMZ has learned.

Sources tell us Brooke wanted to be back home with the kids since Charlie Sheen is now in rehab, and she brought along her sober coaches, therapists and others.

One person said there is so much luggage and so many people in the house "It looks like a circus."

We're told Charlie's mom and dad, Martin Sheen, are also living at the house.

As for Charlie, we're told he's "calm and committed" after his first day of rehab.
