A Taylor Swift fan died Friday night after attending the Eras Tour show in Rio de Janeiro in Brazil’s sweltering temperatures, the Associated Press reported.

The woman — who was 23 years old, according to local reports — was first brought to paramedics after feeling unwell, a statement from show organizers said. She was taken to the Nilton Santos Stadium’s first aid center, then transported to a hospital, where she died. A cause of death has not been announced.
