Billie Joe Armstrong of Green Day has been released from an Italian hospital, WENN is reporting.

The band had to cancel a concert in Bologna, Italy over the weekend when Armstrong was hospitalized.

His fellow band members, Mike Dirnt and Tre Cool, filmed a video message in which they did not specify the nature of Armstrong's illness, but said they were "beyond devastated" and would make up the concert next summer.

Specifics on Armstrong's health were not released, but WENN cites local reports that say the singer suffered "gastric problems" and also report that some Italian fans found themselves in trouble when they tried to visit Armstrong in the hospital.
