Dirnt says in the video, "Hi, this is Mike and Tre from Green Day. Obviously, we apologize profusely ... this is really unfortunate. But due to Billie ... Billie got rushed to the hospital last night due to illness."

He added, "The doctors don't think it's a good idea for him to play today. This sucks. We really, really were looking forward to playing in Bologna as the highlight of our tour."

Cool explained, "We're beyond devastated, we're as sad as you guys are. Billie is extremely upset about it, and we'll see you very soon."
