Charlie Sheen allegedly threatened to pay $20,000 to have his ex-fiancée's "head kicked in".
The 50-year-old actor - who revealed to the world he was HIV-positive last year - vowed to have his former lover Brett Rossi, whom he split from in 2014, beaten after she sued him for assault and battery as well as exposing her to the sexually transmitted virus.
In a 35-minute audio recording obtained by National Enquirer magazine and provided to Radar Online, the former 'Two and a Half Men' can allegedly be heard telling a now ex-lover who is not Rossi his plan.
He said: "This piece of s**t needs to be f***ing buried ... Family of gangsters. You get it. I can't be f***ing extorted. It's called treason. You know what treason is? It's punishable by death. I'd rather spend 20 grand to have her head kicked in. Then people will realise."
Brett - real name is Scottine Ross - filed a $5 million lawsuit against Charlie last year after he allegedly failed to tell her he had the disease until after they had engaged in unprotected sex five times and she found his medication.
She also claimed the actor, whom she dated from 2013 until 2014 and had a brief engagement with, had forced her to have an abortion and was physically abusive towards her.
Charlie has denied all of the allegations and reportedly refused to settle the suit out of court with her for $1 million.
Last November - one month before Brett filed the lawsuit - Charlie announced he had HIV via a live TV interview on the 'Today' show with NBC host Matt Lauer.
