A spokesman for Amy Winehouse says the singer has had to miss a concert date in Paris because of illness.
Spokesman Chris Goodman says the soul diva fell sick at home and could not travel to France for Friday's Rock En Seine show.
Goodman says Winehouse remained at her home and has not been hospitalised. He gave no further details of her illness.
Winehouse's next scheduled gig is at England's Bestival music fest next weekend. Her father has said that after that show she will take time off to focus on her health.
The 24-year-old singer has struggled with drug use and health problems. She was admitted to a London clinic in June after collapsing at home and also spent a night in a London hospital last month.
