Charlie Sheen left a voice message for his ex-wife Denise Richards, in 2008, saying: “I hope you rot in f****n' hell. You’re a piece of s***, f***in' liar. … I hope I never f******’ talk to you again you f****ng c***. You’re a coward and a liar and a f****ng n*****.” Denise is white. He later issued an apology for his “choice of words.”
