An undisclosed health issue has forced the cancellation of Lauryn Hill’s entire European tour.

The Fugees’ former lead singer had been scheduled to headline the Stockholm Jazz Festival on July 15. Performances in Sweden, Greece, the Netherlands, Poland, Germany, Italy, France and Austria were to follow.

Hill’s agent gave no further details while contacting festival organizers earlier this week.

Those shows would have come nearly 10 years after the debut of The Miseducation of Lauryn Hill. That album went on to see five Grammys after its release in 1998.

Since that time, the R&B singer has spent most of her time out of the limelight. Lauryn and her boyfriend, Rohan Marley, currently have five children together.
