Charlie Sheen has been accused of just about every type of sordid behavior imaginable over the course of his 52 years as a tiger-blood guzzling warlock from Mars.

But before today, the Sheenius had never been publicly accused of taking a human life.

Sadly, the actor/human chemistry experiment will now be forced to cross that item off his resumé (or bucket list - this is Charlie Sheen we're talking about) thanks to a mind-blowing new interview with his former friend, baseball legend Lenny Dykstra.

The notorious bad boys were BFFs for more than 20 years.

They first hung out together in 1993, partying in exactly they way you would expect from guys nicknamed Chuckles and Nails, respectively.

According to Dykstra, he stopped by Sheen's house, and the two of them proceeded to get "hammered" and bond over automatic weapons and $3,000 bottles of wine.

Several sh-tty years later, as Kenny Powers would say, Dykstra has done hard time and is no longer on speaking terms with Sheen.

Dykstra shared all of these details and revealed exactly why he chose to end his relationship with Sheen in a stunningly candid conversation with The Hollywood Reporter.

After retiring from baseball, Dykstra embarked on a number of sketchy business ventures, amassing more than $58 million and losing it all shortly thereafter.

In 2011, after being charged with indecent exposure, drug possession, grand theft auto, identity theft and filing false financial statements, Dykstra was sentenced to three years in prison.

He claims that in the months before his sentence began, he became a sort of personal assistant to Sheen, arranging deals and offering advice that the troubled star rarely took.

Dykstra says he attempted to convince Sheen to come forward with his HIV diagnosis more than a year before the actor revealed his illness publicly.

The Philadelphia Phillies icon adds that these days, Sheen is living a tortured existence - alienated from most of his inner circle and facing a tax fraud investigation that might eventually land him behind bars.

Dykstra reveals to THR that he first realized how far Sheen had fallen when witnessing the near-fatal drug binge that coincided with Sheen's famous "meltdown." 

"When [the OxyContin pills] are at their peak, it's a euphoria, where you're smart and you're creative and you're quick and you're invincible," Dykstra says of the famous 2011 interview in which Sheen introduced "winning" to the pop culture lexicon.

Dykstra says he last saw Sheen in 2014 and found him to be a shell of his former self:

"It was right out of a mystery spy thriller, with a sliding bookcase," he says.

"I walked in and Charlie was standing there with a glass dick — a crack pipe — in one hand and his phone in the other. I took one look around, there's all this stuff, cool paintings and Babe Ruth's ring, and I said, 'Charlie, I have to admit, if you're going to smoke crack, this has got to be the best crack den on the planet!' That broke the ice."

But the most shocking revelation has to do with Sheen's former friend and de facto assistant, Rick Calamoro, who was found dead of an apparent accidental overdose in 2012.

Dykstra claims that after Calamaro insinuated himself in Sheen's social circle, many began to suspect that he had done so with plans to write a tell-all book about the actor:

"Before I went [to jail], I said, 'Dude, this guy, he is writing a f-cking book, you got to fire him,'" Dykstra recalls.

After he was released from jail, Dykstra says he confronted Sheen about Calamaro's death:

"What the fuck happened to Calamaro?" Dykstra remembers asking.

"He said, 'You mean Dead Rick? What f-cking happened is the motherf-cker tried to blackmail me just like you said — wanted $5 million. I had him fucking iced.' He said he had a hot dose put in there,"

Dykstra says "hot dose" is slang for an intentionally lethal dose of an intravenous drug that can be used to murder a user without suspicion.

Interestingly, Dykstra says he's come to terms with Sheen's alleged murder, but remains distraught over charges that Sheen assaulted his former fiancée Brett Rossi.

"Killing the guy that fucking tried to extort him: That's his business," he says. But what Rossi alleges happened to her is too much for him. "Men, they get in rages. But no pummeling."

THR also spoke with Rossi, who details her allegedly abusive relationship with Sheen, and says she believes her ex to be capable of murder.

Not surprisingly, Sheen could not be reached for comment, but we're guessing he would've muttered something about "Adonis DNA."
