Lauryn Hill [ tickets ] has canceled all of the dates on her European summer tour, according to a story posted by OK! Magazine.

Hill's agent reportedly told organizers of the Stockholm Jazz Festival, which the former Fugee had been slated to headline, that all of her client's scheduled European dates have been canceled due to unspecified health reasons.

The European concert dates were expected to mark Hill's return to the concert circuit; she has performed only sparingly and hasn't released an album of new material since 1998's "The Miseducation of Lauryn Hill."
