Amy Winehouse is facing legal action after pulling out of a concert in Paris hours before she was due to go on stage.
The troubled singer failed to appear at the Rock En Seine festival in Paris after she was taken ill at her house in London at the weekend and was unable to travel to France.
A statement posted on the festival website said organisers had decided to start legal proceedings against Winehouse because of the circumstances of her cancellation.
The statement said: "We were told by [Winehouse's] agent at 8pm that she would not be there and we were forced to cancel the performance.
"We have still not been given any explanation of the exact reasons for her absence."
Winehouse had been due to headline a bill that included the Raconteurs, The Streets and Kate Nash at the Saint Cloud Park just outside Paris.
A spokesman for the singer said: "Amy Winehouse is currently at home recovering. The illness is nothing serious, nothing that some time in bed, and not singing, won't cure."
He also confirmed that she would still be performing on 6 September when she is due to headline the Bestival festival on the Isle of Wight.
