Charlie Sheen and Selma Blair are in desperate need of some anger management.

Charlie has allegedly fired his Anger Management co-star and refuses to shoot with her on set after she badmouthed him to network execs, TMZ reports.

According to TMZ, Selma recently complained to their bosses about Charlie's poor work ethic and constant tardiness. When Charlie got wind of the news, he allegedly fired the actress and told FX to support his decision considering the fact that he's the star of the show and has 40 pages of lines per episode as opposed to Selma's two.

It's unclear whether Charlie has the authority to let the actress go in the first place. However, he's reportedly already pining after another female lead. He wants to hire Mila Kunis for a 10-episode stint at $1 million per episode. We wonder how his Two and a Half Men replacement Ashton Kutcher (Mila's boyfriend) would feel about that.

His tiger's blood is really boiling!

After private flirty text messages between Charlie Sheen and Backdoor Teen Mom star Farrah Abraham were made public yesterday, the Anger Management star pointed the finger at the newly minted porn star as the culprit of a shameless publicity stunt, and decided to write a scathing letter slamming her for being desperate for fame!

The bad boy actor reached out to the MTV reality star with this open letter to TMZ:

hey, you desperate guzzler of stagnant douche agua;

I truly do not recall giving you permission to globally reveal any communication between us. congrats on surviving your lobotomy and an even bigger congratz on the recent attempt at porn.

your daughter must be so proud.

please send my number to middle earth and if allowed, eagerly follow it into said abyss and slam the door behind you. the world will collectively sigh as the pungent memory of you vanishes into the pedestrian troposphere of lame-suck and zero-life.

oh and I'm sure they'll wave the cover charge when they see your tranny-boobs and five o'clock shadow.

bye!
cs.

The single mother reached out to Sheen about a possible meet-up in late May, which the Hot Shots! star seemed totally down for until she exposed their text messages. Don't hold your breath for a coffee date anymore, Farrah!

She's bound to be pissed!

Charlie Sheen appeared on the Tonight Show with Jay Leno yesterday, and the Hollywood bad boy dished all about the rumors his Scary Movie 5 co-star was a nightmare on-set during a recent guest appearance on his show Anger Management.

Lilo reportedly held up production and stole jewelry from the set, but Charlie said that wasn't true exactly...

"Day one was fabulous. She was on time, she knew her lines, hit every mark, made us look off our game... And then we had to deal with day two," he told the talk show host.

So what happened day two exactly? According to the actor, the rehabbed redhead showed up two hours late, claiming she was suffering from an earache.

"It was as though she had us held hostage because she gave us half a show. She was really not feeling well. We just worked around it. She was late, what can I say? But when she got there, she was prepared. With an excuse," he explained.

And the rumors about her sticky fingers with a bracelet from the wardrobe department?

"She borrowed some stuff and was told she had to pay for it and they would take it out of her check, and she said fine. That's all it was," he added.

Mr. Sheen should have thought twice about commenting on the situation, considering he has to see her tonight at the Scary Movie 5 premiere in L.A.

X17online will be on the red carpet tonight, so check back later for all the photos from the Scary Movie 5 premiere!

Lindsay Lohan prides herself on "keeping a low profile," as she says in this new Scary Movie 5 clip. Between the hot mess that is Lilo and Charlie Sheen's hot messiness, we think this fifth installation of the hit franchise could be the biggest yet.

The film's premiere is this Thursday in LA and Lindsay's scheduled to walk the red carpet. It'll be the first time she's returned to LA since a judge ordered her to go to rehab March 17. She's still got until May 2 to advise the court which facility she's chosen -- check out THIS story to see some of her options ...

Did someone indulge in a little too much tiger's blood?

While the rest of Hollywood was at the Dolby Theater attending the Oscars last night, Charlie Sheen was at home mocking the ceremony in a series of bizarre Twitpics!

In one snapshot, the Anger Management actor posed with an iPad down his pants and a packet of vegetables and captioned it, "I'd like to thank Bikram my Yoga teacher. and "Argo" for finally spelling my name right. c #BenIsSmart #Ware'sMatt?"

We're not sure we get where he's going with that!

Another photo shows him clutching a trash can while smoking a cigarette on the floor with the caption, "I'd like to thank Pfizer for all things being PERFECT!!! c #hashgag911 #gashSlag119 smashFlag... mom?"

That sounds like a shout out to the pharmaceutical company, but is he also implying prescription drugs were being consumed? We're so confused!

Whatever was going at Casa de Sheen last night seemed like one wild time!

Just call him big-hearted Chuck!

Charlie Sheen was a guest on The Tonight Show with Jay Leno last night, and the Anger Management actor had nothing but nice things to say when asked about Lindsay Lohan, to whom he famously wrote a $100,000 check to help with her tax debts.

"She's terrific I mean she's going through a lot of stuff. She's smart and super fabulous and I think will come out on top eventually, you know," he told the talk show host.

So how did the veteran TV actor explain his random act of generosity towards the rehabbed redhead?

"They offered me a decent amount of cash to do Scary Five as a cameo. Then they said they're going to hire Lindsay. I thought fabulous. They took half my money to give to her and she didn't get it all. And when I found this out I said you got shorted a hundred grand so I, gave it to her," he put bluntly.

The Hollywood bad boy might have a soft spot for Lilo, but the same can't be said for shamed cyclist Lance Amstrong, who he met at a party back in 2005.

"He was kind of a douche. He was talking to, I think he was talking to Sheryl Crow at the time. I said, 'Hi Mr. Armstrong, I'm Charlie Sheen. I just wanna say hello.' He looks at me, he's like, 'That's nice,'" he revealed.

Who knew under the tough guy exterior there was such a softie?

His tiger's blood wasn't the result of substance abuse!

Charlie Sheen made an appearance on the Late Show with David Letterman last night, and the veteran actor talked all about the circumstances that led up to his firing from Two and a Half Men and subsequent meltdown last year.

Asked by the talk show host if crack cocaine was to blame for his bizarre antics, the bad boy quipped, "I wish it was crack cocaine. I wish it was an ocean of vodka, a bathtub full of pills," adding, "It was just my brain was kind of separated into itself. I just had to take a stand for what I know was right."

So drugs played no part in all the drama?

"Not during the meltdown," he said. "During the previous 30 years of my life, sure."

His new show Anger Management has won Mr. Sheen rave reviews, so it seems as if things are finally on an upswing for Hollywood's favorite party boy!

Now he just needs to give up his nasty smoking habit!

Charlie Sheen made an appearance at the FOX TCAs to promote Anger Management, and while he chatted with Extra about his hit series, we're more interested in what he had to say about his Scary Movie 5 co-star Lindsay Lohan!

When asked about Lilo, Charlie told the show, “She's a good gal you know and I've been through a lot of the same stuff and it's like I told her when I met her, just don't take it so seriously, just lead with humor and lead with your heart and the rest will work itself out.” So what about the $100,000 tax bill? "I hope it helped and I just believe in paying it forward," he said, adding that she sent him a thank you note too. "She was very cool about that ... she's a sweet lady and I'm rooting for her."

And speaking of ladies in his life, how is ex-wife Brooke Mueller doing these days? "She's doing alright. Yes, as good as Brooke can do, she's doing fine, yeah.”

Sheen also opened up about the controversy surrounding the photo he posted of himself with Los Angeles Mayor Antonio Villaraigosa in Cabo, which seemed to suggest the two were partying it up in Mexico. "The whole thing was blown out," he said. "I was just trying to make a joke and I feel bad because he's such a good mayor and he's such a good dude. I wasn't trying to do anything then just try to get a few laughs out of it and let people know that we had a good time in Cabo and I don't know I guess I should have taken it a little more seriously ... his position and what he's responsible for and the type of stuff he has to deal with and I wasn't respectful of that so that's on me. That's on me. Sorry, Antonio.”
