Chaka Khan has canceled her concert at the California State Fair two days before her show, announcing she that she has entered into rehab for drug addiction.

Fair officials reportedly received a message from Khan’s rep on Saturday, saying that the 10-time Grammy winner was entering an inpatient and aftercare program for addiction to prescription pain medication.

Khan has been open in the past about her addiction to drugs in the past.

The outlet reports that other July performances have been cancelled and that Jody Watley featuring Shalamar Reloaded will perform in Khan’s place at the fair.
