Amy Winehouse's friends are said to have put the singer on suicide watch after she allegedly threatened to kill herself with a knife.
Winehouse is said to have made the claim after her husband, Blake Fielder-Civil, was refused an early release from prison.
Fielder-Civil is currently serving a 27-month sentence after pleading guilty to assault and perverting the course of justice.
A source told the Daily Star: “Amy said she was ‘caught up in a nightmare’. Her friends managed to get the knife away from her but are now holding a 24-hour watch on her.
“Amy has a death wish. Her emotions are exaggerated. She is either high as a kite or, when she hears something she doesn’t like, she’s suicidal.”
A spokesperson for the star has since told US publication People that the reports are not true, and that the singer is "fine".
Fans raised fears about Winehouse's health earlier this month after she performed at a charity event in London looking gaunt.
Winehouse played a short set alongside her goddaughter, Dionne, for specially invited guests.
