Amy Winehouse has been forced to cancel a European festival performance due to illness.

The singer, 24, was due to take to the stage at the Rock en Seine show in Paris on Friday night, but the singer’s U.K. rep, Chris Goodman, confirmed she was too unwell and had to cancel. “She was taken ill at her house and wasn’t able to travel to France for the concert,” Goodman said in statement.

Admitted to the hospital last month after suffering an allergic reaction to her anti-drug medication, Winehouse’s no-show prompted a fresh wave of concern for the troubled singer.

But her rep Goodman insists the illness is “normal” and nothing to do with medication or her battle with drugs. “It’s nothing serious,” Goodman tells PEOPLE. “It’s just a normal illness – she hasn’t visited a hospital or anything like that. She’s at home in bed, just unable to sing.”

Winehouse’s next scheduled performance is on Sept. 6 when she is due to headline the Bestival music festival on the Isle of Wight in England.
