Charlie Sheen "never realised how f***ed up" he was until his Comedy Roast this weekend.
A cast of comedians and stars - including guitarist Slash, boxer Mike Tyson and Charlie's ex-wife Brooke Mueller - gathered for the event, which saw comics make fun of the last year of the actor's life, which has seen him struggle with drug addiction, fired from sitcom Two and a Half Men and have a polyamorous relationship with an ex-porn star and a marijuana magazine model.
Sheen sat on stage on a huge throne, surrounded by prop missiles, and was introduced by the night's host, Family Guy creator Seth McFarlane.
He said: "You've seen him on TV. You've seen him in movies. And if you are a prostitute, you have seen him point a gun at your head."
He also referred to an incident at Christmas 2009, when Charlie allegedly threatened Brooke with a knife, saying: "She's here voluntarily, no one put a knife to her throat."
