Charlie Sheen's ex-wife warned people on "Two and a Half Men" that Charlie needed help badly ... sources tell TMZ.

We've learned Denise Richards contacted an exec from the show Monday morning and said she was concerned about Charlie relapsing and wanted someone to step in and convince him to go to rehab.

Sources connected with the show tell us when Charlie did not show up for work on Monday or Tuesday, it became apparent to "Two and a Half Men's" Executive Producer Chuck Lorre that Friday's filming was in jeopardy.

We're told Charlie himself realized the show, along with his freedom because of the whole bail issue, were on the line ... and that is what forced his hand.

More sources have come forward and confirmed TMZ's story ... that Charlie is the one who made the decision to go to rehab.

And something else: Our sources say at 10:30 AM yesterday a plan was in place to admit Charlie at 8:00 PM to the rehab facility. In other words, Charlie didn't get cold feet.

As we first reported, the plan is for Charlie to return to the set two weeks from Monday. If that happens, Warner Bros. can deliver the remaining 6 episodes for the season to CBS on time.

Filed By: Van F. Alexander

Reason: Claims he was hired as Michael Jackson's "Media and Communications Consultant" for $10,000 a month, and wasn't paid from January to July of 2008.

Grand Total: $70,000.

Will he get it? Who knows.

FIN

Charlie Sheen could go back to jail because he has violated the terms of his bail -- specifically by using drugs or alcohol. But sources tell us Charlie's people are confident they will dodge this bullet.

As we already reported, Charlie has not been clean and sober recently. But proving he slipped in a court of law is a whole different matter, and Charlie's reps are now confident info about his alcohol and drug use will remain under wraps.

We reported last night that the delay in checking Charlie into rehab was to make sure his legal position was not compromised in the criminal case.

The prosecutor in the case sounded surprised when we told him that last night, but Charlie's people are confident information about the "Two and a Half Men" star has been contained and will remain private -- at least in terms of admissible evidence of drug and alcohol use.

As for his show, sources tell us Warner Bros. can deliver the remaining 6 episodes to CBS, provided Charlie is back on set in two weeks from next Monday.

Charlie Sheen arrived at a rehab facility in the L.A. County area at 8 PM PT Tuesday ... TMZ has learned.

Sheen's rep said earlier in the day the "Two and a Half Men" star was already in rehab.

But sources tell TMZ there were several delays, primarily because Sheen's team wanted to make sure there were no legal ramifications resulting from Charlie's move.

Sources tell us Charlie had been "slipping" and that's why he decided to go into rehab.

TMZ contacted Arnold Mordkin, the prosecutor in Charlie's criminal case in Aspen, to find out if he was contacted by Charlie's lawyers and whether he gave any assurance he would not try and revoke Charlie's bail. Under the terms of bail, Charlie cannot take drugs or drink alcohol.

Mordkin sounded surprised but said he could not comment one way or the other.

As we first reported, Charlie is not in the same rehab facility as his wife, Brooke Mueller.

As for their kids, they were sleeping soundly Tuesday night. Charlie's mom was at the house and Martin Sheen joined her after performing his play in L.A.

Yung Berg -- the guy who rapped on the song "Sexy Can I" -- was violently beaten and robbed at a house in Los Angeles this weekend ... TMZ has learned.

According to law enforcement sources, Berg -- real name Christian Ward -- was at a house party at around 2:00 AM Monday morning when four suspects entered the home and brandished firearms.

We're told the suspects pistol-whipped two people inside the party -- one of whom was Berg. Law enforcement sources say the suspects robbed eight people and made off with $10,000 in cash and jewelry.

Katt Williams may have seriously fenced himself in this time -- and it's all over a pile of cash he allegedly owes a construction company.

Extreme Fence Co. filed a lien against the comedian last month, claiming they installed an electric motorized gate and 106 feet of wrought iron fence at his Calabasas, CA home back in October ... but never got paid for the job.

EFC claims the bill came to $8,900 -- and now they want their money, stat.

Katt's reps did not return e-mails.

The caller, who freaked out as the call goes on, tells the dispatcher about the fight at the Commons in Calabasas between Travis, his people, and several photogs.

Charlie Sheen voluntarily checked himself into rehab and there was "no one big thing that happened that made him go" -- a very well-connected source tells TMZ.

We're told Charlie made the decision to go to rehab late this morning.

As for the kids, we've learned they will stay at the family house with the nannies and other staff. We're told Charlie's mom will spend a good deal of time at the house, as will Brooke Mueller's mother.

The kids will visit Brooke in her rehab facility.

As we first reported, Charlie will spend two weeks in rehab. We're told he will get outpatient treatment once he checks out.

CBS and Warner Bros. just issued a joint statement, saying: "CBS, Warner Bros. Television and Chuck Lorre support Charlie Sheen in his decision today to begin voluntary in-patient care at a treatment center."

Charlie Sheen will spend two weeks in rehab, sources tell TMZ.

We've learned over the last week Charlie told people involved with "Two and a Half Men" that he was getting outpatient help for a problem, though he never specifically said drugs or alcohol.

We're told Charlie has informed the show's producers he will be back in two weeks. "Two and a Half Men" is set to take a one week hiatus in two weeks, so Charlie would not be on the set for 3 weeks.

We're told there are 6 episodes left to tape for the season. And there's this ... Charlie's deal is up at the end of the season. He's renegotiating with Warner Bros. but the recent turn of events won't help his negotiating position.

Charlie Sheen's wife, Brooke Mueller, currently has the couple's two children at the rehab facility she's at ... sources tell TMZ.

Sources tell us Mueller's rehab facility allows children, and Brooke's kids are with her right now, along with the nannies and a counselor.

As we first reported, Brooke is now in a private home that offers high-end rehab services and allows patients to bring children and staff. She checked out of The Canyon in Malibu after an alleged security breach.

Up to this point she was sharing custody with Charlie -- in other words, she did not have the kids full-time.

We do not know if Brooke will have the kids full-time now that Charlie himself is in rehab.

Story developing ...

Chris Golightly was booted from the show because he had a record deal when he auditioned in Hollywood last year.

At a news conference today, Golightly produced a document showing he had been released from his record deal before he auditioned at "Idol."

But a few minutes ago, Lawrence D. Franklin, CEO of Dream Project Entertainment, told TMZ after Golightly got disqualified, he approached Franklin and together they phonied a document, backdating the release of his contract to June 7, 2009.

Why did Franklin come clean if he was in on the deception you ask? Franklin tells us ... he belatedly wanted to do the right thing.

Meanwhile, Chris' people say Franklin is full of it.

Charlie Sheen's decision to enter rehab came abruptly today and he is not at the same facility as his wife, Brooke Mueller.

We're told there is deep concern that Charlie could have his bail revoked in Colorado -- one of the terms is that he not consume drugs or alcohol.

Sources tell TMZ Charlie did not show up for work on "Two and a Half Men" yesterday -- although he sometimes does not show up on Mondays.

When he did not show up today it raised concern and we're told that's when production staff was notified that Charlie was checking into rehab.

As for Charlie's show, his rep says he will be taking "some time off." We're told studio is now scrambling to make sure they can deliver the required number of episodes to CBS. We're told the show definitely will not be shot this week.

UPDATE: Sources connected with "Two and a Half Men" tell TMZ, the show's staff is being told Charlie's treatment is a partnership with his wife's treatment.

UPDATE: Law enforcement sources tell TMZ Priestley's home was not burglarized -- but the suspect did enter Jason's property. We're told nothing was taken from Jason's home. We're told cops apprehended the suspect and property from the other burglaries were recovered.

Jason Priestley from "90210" fame had his L.A. home burglarized last night ... this according to law enforcement sources.

We're told multiple homes were burglarized in Toluca Lake (next to Burbank) where Jason lives.

One suspect is in custody.

Police are on the scene.

Story developing ...

We've learned one of Rachel's friends is approaching Howard's people today, asking that a cardboard version of Rachel in various states of dress could compete against the other living, breathing contestants for the $100,000 prize.

Howard announced today he has 4 live mistresses signed up ... so far. But he's not saying who. We're thinking even a cardboard Rachel could beat a toothless Jaimee Grubbs or a shameless Joslyn James.

"Star Trek" star Walter Koenig -- father of missing "Growing Pains" actor Andrew Koenig -- is leaving for Vancouver in a few hours to get briefed on the search for his missing son.

Walter tells TMZ his son's been depressed before ... but this is the first time he's straight up disappeared.

Walter and his wife plan to stay near Stanley Park, where their son was last seen on Valentine's Day.

Walter had been aware that Andrew cleaned out his Los Angeles apartment but had no idea his son planned to move to Vancouver ... which Andrew told friends before he disappeared.

According to Walter, Andrew told him he was only there to visit acting school friends.

Missing "Growing Pains" star Andrew Koenig emptied out his apartment in Venice, CA because he wanted to start over in Vancouver ... this according to a long-time friend.

Lance Miccio tells TMZ he went to Koenig's apartment last night and found it cleaned out.

Miccio says Koenig told friends two weeks ago he planned to move back to Vancouver to "start over," because he considered Vancouver his "place for solace."

Koenig -- son of "Star Trek" star Walter Koenig -- was last seen February 14 in Vancouver. Cops told us there have been reported sightings of Koenig since he went missing, and that they are still looking "for a living person."
