Forget "Two and a Half Men" -- TMZ has learned Charlie Sheen has hooked up with three whole porn stars in Las Vegas -- all at the same time ... during what we're being told is an epic bender.

We've learned Charlie hooked up with the three women -- who are in Vegas for a porn convention.

The foursome is holed up at The Palms Hotel and Casino.

As TMZ first reported, Sheen was seen today hammering down Grey Goose Vodka in the hotel bar.

Charlie is due back on the set tomorrow, and everyone around him -- from studio execs to members of his team -- is deeply concerned for his welfare and wants him to go to rehab.

As far as we know ... Sheen hasn't checked in with anyone today.

Charlie Sheen is supposed to be on the set of "Two and a Half Men" at 10 AM PT ... exactly 2 hours from the time this story was posted. But TMZ has learned he's still in Las Vegas.

TMZ broke the story ... Charlie was on a bender over the weekend, holed up with three porn stars, including Bree Olson.

Charlie's people, as well as suits from the studio ... are deeply concerned for him. We're told Charlie's people have been trying to get him in rehab but he doesn't think he has a problem.

Charlie hasn't communicated with the people from "Two and a Half Men" yesterday or today.

Stay tuned.

Here's their chance to do what they should have done a year ago: shut down production of the show until he can get help. Or else they can fire him over this and sue him for breach of contract.

Isn't this clown one of the highest paid actors on TV? What a waste of money.

You can't force an alcoholic into rehab. He has to realize for himself that he has a problem and going to rehab has to be his own choice. Perhaps if Charlie Sheen is fired and sued for breach of contract that might be the wake up call he needs to to realize that he has a problem.

Not only is he ruining his life, he's putting other people out of work.

WBTV & CBS Fight To "Save" Charlie Sheen (http://www.deadline.com/2011/01/the-fight-to-save-charlie-sheen/)

By Nellie Andreeva | Tuesday January 11, 2011 @ 10:14am PST

As Warner Bros TV and CBS nervously await to see if Two and a Half Men star Charlie Sheen will show up for work today after his weekend binge in Las Vegas (he is due at the studio later this morning), WBTV, the network, as well as the producers of the hit CBS comedy continue to search for ways to get Sheen help. I hear Sheen, described as a functioning addict, returned to work from holiday hiatus last week visibly slimmer (some estimate he may have lost as much as 25 lb.) His drastically changed appearance led to WBTV and CBS ramping up their efforts to shut down production on the show in the short term so Sheen can get clean.

But that didn't fly with Sheen who has consistently refused to go to rehab. I hear he has retained lead litigator Marty Singer and has threatened to sue Warner Bros TV and CBS if they shut down production on the show without cause. And, with him refusing to see a doctor, the studio and the network would have to stop production with no legal reason. Additionally, if he refuses to enter rehab, staying at home instead of working would probably do more harm than good - Sheen seems to mostly get in trouble when he is off work, including his domestic violence arrest in December 2009 and his New York hospitalization this past November after a hotel room rampage.

WBTV, which signed Sheen in a new 2-year deal in May, as well as CBS have tried to help Sheen in different ways -- I hear upon request from CBS Corp. CEO Leslie Moonves, Sheen took in a sober living partner after the New York hotel incident. But that coach is no longer with him. Things came to a head last week when WBTV and CBS executives, concerned about Sheen's well-being after the extreme weight loss, were in constant communication with Sheen and his team about shutting down production on the show. I hear there was even a statement to that effect prepared by CBS and WBTV on Friday. But, with resistance from Sheen, the statement about the production shutdown was never released.

Sheen was also slated to attend a high-level powwow with network and studio executives after the Friday taping of the show, but he reportedly bolted out right away, skipping the meeting. Another sit-down with him was scheduled for this week.

Then came the disturbing TMZ item yesterday that Sheen was seen hammering vodka at a Las Vegas hotel where he had been spending time in the company of porn actresses this past weekend. Which leads us to this morning. Sheen has not missed his call time yet and may very well show up for work as he normally does. But the people on the show who have worked with him for 7 years and care about him fear they may be running out of time to help the comedy star before it's too late.

This kind of reminds me a bit of how Mackenzie Phillips hamstrung the cast and crew of One Day at a Time with her drug habit and missing/showing up late to tapings and rehearsals. Thankfully, the show was able to go on because the core of Bonnie Franklin, Val Bertinelli and Pat Harrington were still around and stepped up their game. Sadly, I don't think the cast and crew of this show can go on without CS. They might be out of jobs soon and it's all his fault!!

I'm sorry for the folks who are impacted by Sheen's alcoholism, but I can't say I'll miss this show if it goes.

Hopefully Sheen's family and friends can stage an intervention, but as Marv correctly pointed out, the only one who can make a real change is Sheen himself. Here's hoping he makes that decision before it's too late.

I'm sorry for the folks who are impacted by Sheen's alcoholism, but I can't say I'll miss this show if it goes.

That makes two of us!! My brother and dad LOVE this show. I, on the other hand, tried to watch an episode and didn't last 5 minutes before I got up and left the room. I honestly don't understand what others see in this program. :confused: To each his/her own, I guess.

I can just hear David Letterman Top Ten Now

The big adult convention going on in Vegas is the AVN Adult Entertainment Expo (pretty much the equivalent of the OSCARS for adult movies).

I was reading that Andy Dick was also at the event and he was thrown out for harassing some of the adult movie stars. :crazy:

If it would help Charlie, I would make the ultimate sacrifice and trade places with him.

well they have since made a statement that this was all just a bunch of confusion and Charlie didn't show up because of an ear infection.

...and those porn stars were just helping him put in his ear drops because they are good at that sort of thing.
