We're told MiLo had the emergency procedure done, which determined he has a blockage in the posterior interventricular artery of his heart.

According to our sources, the blockage is being treated by his doc, Dr. Farzan Rajput of Newport Beach, who believes Michael can make a full recovery.

UPDATE: Lohan was spotted a little while ago at a Jack in the Box around the corner from the hospital. He wasn't pleased to see to the photogs and never actually went inside.

Sources connected with the show tell us ... although nothing is in stone ... they're told by the addiction specialist that Charlie could be back to work next month. If that happens, producers would most likely make up the two missed shows at the end of the production season.

Halle and Gabriel are locked in what has turned into an epic custody war. Sources tell us ... while Gabriel was dating someone last year ... he claims Halle would call, screaming and swearing at him in a jealous rage.

Gabriel is claiming ... when he went to London and South Africa with Halle and Nahla last August when she was shooting a movie, Halle would sometimes not return for days, when she was supposed to care for the toddler.

Gabriel also claims Halle cares more about dating than parenting.

But our sources say Halle says it's the opposite -- that Gabriel is petty, jealous and irresponsible. But the most serious allegation ... we're told Halle believes Gabriel put Nahla in immediate harm's way by being inattentive while the child was in his care.

Kenny Ortega was sued by Katherine, who claimed he was part of AEG's alleged plan to give Michael anything he needed in order for him to perform.

Katherine's lawyer, Kevin Boyle, tells TMZ, "Based on recently discovered information, the Jackson family has determined that Mr. Ortega should not be a defendant," adding, "The Jackson Family apologizes for any discomfort or inconvenience this may have caused Mr. Ortega."

It's always a discomfort to be sued for wrongful death.

Lindsay was out at dinner in West Hollywood Sunday night when she ran into the cast (minus Jane Lynch and Lea Michele) ... and naturally, that episode -- mocking Lindsay's frequent trips to rehab -- came up .

Sources tell us the cast walked up to LiLo ... apologized for the jokes ... and said they didn't mean to hurt her feelings. Lindsay accepted their apology and everyone parted ways.

We're told Michael was at a doctor's office in Newport Beach, CA for a consultation about getting his nose fixed -- a nose which has been broken several times over the years.

Michael began complaining of chest pains, so the nurse took his blood pressure which alarmed her enough to call 911. We're told his blood pressure was 200/110.

Michael is en route to Hoag Hospital in Newport Beach.

Halle's rep tells TMZ, "Halle has serious concerns for her daughter's well-being while in the care of her father for any extended period of time and is prepared to take all necessary steps to protect her."

According to the rep, Halle will go to court and has canceled an upcoming film production in New York this week to handle the matter.

Sources connected with the actor tell us ... CBS, Warner Bros. and Charlie put their heads together and found an expert in addiction they think can help Charlie conquer his demons.

The expert and other professionals are coming to Charlie's gated community in L.A., in no small part for privacy reasons. Many rehab facilities can be tricky when it comes to patients and others spilling secrets.

UPDATE: Denise Richards has been spotted driving in and out of Charlie's gated community twice in the last 24 hours. Below, a shot of her driving out last night.

And we've learned ... Eva's lawyer quietly filed papers Friday to dismiss the divorce petition she filed in L.A. County Superior Court.

Sources familiar with the case tell TMZ both sides agreed that Texas was the proper place for the divorce because that's where the prenup was signed.

TMZ broke the story about the dueling divorce petitions, but ultimately there was no conflict.

We're told all issues connected with the divorce have been resolved and it was done in a very amicable way.

Turns out after Britney and Kevin split, Kacey Jordan and K-Fed dated briefly. We're told K-Jor spent a lot of time at K-Fed's house and would even babysit the kids from time to time when he would go out and do ... whatever it is he does.

Kacey tells TMZ, "I watched the kids when Kevin was dealing with the divorce. He was busy with going to so many meetings with lawyers. We went swimming ... they were great."

The house, located in the Hollywood Hills, is 8,000 square feet on 1.29 acres. It's had a long history since Brittany passed away in December 2009. Back in March 2010, Brittany's mom Sharon put the home on the market with an asking price of $7.25 million.

Then in April 2010, Brittany's mom decided to pull the house off the market. About seven weeks later, Monjack was found dead in the home.

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 involved in the bender tell us ... Sheen broke out his checkbook during a conversation with a porn star Wednesday in which he asked her to join the "porn family" he wants to create.

We're told Sheen -- in a showing of good faith -- wrote a $30,000 check made out to "cash" and told the porn star to take it to the bank ... and the money was hers.

Obviously, the porn star darted for her car -- and when she got to the bank, the teller called Charlie AND one of Sheen's business associates to verify the transaction. Luckily for the porn star, it cleared.

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.

Law enforcement sources tell TMZ, Summit Entertainment -- which is distributing Mel's upcoming movie, "The Beaver" -- gave Mel the final cut of the movie on DVD. Mel screened it at his home, and at 10:45 AM put the DVD in his mailbox so a courier could pick it up and return it to Summit.

We're told the courier showed up at 2:30 PM Wednesday, and the DVD was missing.

The L.A. County Sheriff's Department is now on the case. But here's the sad part -- It's being investigated as a petty theft.

The talk was supposed to go down next month during the University's "Sexual Responsibility Week" -- but a rep for the school tells TMZ, it ain't gonna happen ... "because of the growing controversy among undergraduates over the decision to pay for [Bristol's] talk with student-generated funds."

Bristol -- a spokesperson for the prevention of teen pregnancy -- was supposed to give a brief lecture on abstinence.
