Amy Winehouse has withdrawn from a Parisian festival hours before she was due to perform.
The 24-year-old did not travel to the Rock En Seine festival due to an illness which resulted in her needing to rest, according to her spokesman.
The Rehab star was hospitalised in June and diagnosed with early stage emphysema before another hospital visit last month after suffering a reaction to medication while at her north London home.
Her father Mitch had reportedly claimed that his daughter's drink had been spiked with ecstasy, but according to Winehouse's mother Janis, the hospital visit was simply a matter of human error.
"The truth is that Amy ended up in hospital this week because she mixed up the medication she's taking to help her come off drugs," she told the Daily Mirror newspaper.
"She took a wrong tablet."
Commenting on her withdrawal from the Rock En Seine lineup, her spokesman said: "Amy Winehouse was regrettably unable to perform at the Rock En Seine show in Paris due to illness.
"She was taken ill at her house and wasn't able to travel to France for the concert."
She has performed at the Glastonbury and V festivals this summer and is due to take to the stage at Bestival next weekend.
