The 47-year-old has admitted she is still angry with her late husband, who committed suicide in 1994 when their daughter Frances Bean was just 20-months old, for his attempts to end his life and battle with heroin addiction.
Asked if she is mad with Cobain for killing himself, she 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***ing kill him. I'd f*** 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***ing EMS [Emergency Medical Services] I was always sticking pins in his balls. I carried around Narcan.'
Courtney also explained the pair had financial problems.
She added: '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?'
