The Hole frontwoman admits she is still "mad" with her late husband - who committed suicide in 1994 when their daughter Frances Bean was just 20 months old - for his multiple attempts to end his life and battle with heroin addiction.
Asked if she is angry with Kurt for killing himself, Courtney told Vanity Fair magazine: "Mad? Ya think?! If he came back right now I`d have to kill him, for what he did to us. I`d f**king kill him. I`d f**k him, and then I`d kill him.
"He tried to kill himself three times. He OD`d at least five times. I was the f**king E.M.S.[Emergency Medical Services] I was always sticking pins in his balls. I carried around Narcan [a drug used to revive heroin users]."
Courtney - who has been estranged from Frances since 2009 - has repeatedly claimed she has been defrauded out of much of Kurt`s money, but has also now insisted her financial problems began long before the rocker`s death.
She said: "We could never find our money. We had $135,000 in our bank account. They said that if he would go do Lollapalooza he would make $11 million- Do you think Kurt would have killed himself if he had known he had $54 million?"
