It's pretty obvious that it's Charlie Sheen the one in question.
I would guess the rumour will be confirmed soon.
He's the one being described. Ex porn star and several of his associates and friends had apparently be leaking the information last year.
You just need to do a search on google and you can dig up all the many rumors from last year.

Makes sense too because where's he been for the last two years? In seclusion it would seem. He was acting pretty weird a few years back also.
With that tiger blood shit etc.. Guy thought he could do anyone.

He completely fits the rumor.
Porn stars, prostitutes, drugs, booze..& on & on..
