Because life always imitates art, Charlie Sheen, star of FX’s ‘Anger Management,’ might be experiencing some anger management difficulties of his own.

Again.

According to a report filed with the LAPD, our resident Vatican Assassin threatened to shoot a former “associate” with a Super 90 semi-automatic rifle. And, clearly, if you’re going to nickname yourself Assassin, the police are going to investigate these kinds of things.

Apparently, Sheen was upset with said Associate -- he deserves a nickname too -- and vented his frustration via text by sending this message to Associate No. 2:

I’ll blow his head off with my Super 90.

Someone in the Sheen camp -- probably hoping to escape the same fate -- explained away the incident to TMZ by saying, “The accuser is a dishonorably discharged military person with multiple probation violations who is trying to shake [Charlie] down for money.”

The case is still in the early stages of investigation and the cops have yet to speak with Sheen, but here's a little survival tip: Shaking down unstable celebrities with semi-automatic weaponry is always a bad idea.
