Three days after Green Day were forced to cancel a show in Bologna, Italy following frontman Billie Joe Armstrong's hospitalization, Mike Dirnt and Tre Cool were backstage at the Staples Center in Los Angeles getting ready to perform at the 2012 MTV Video Music Awards, which will air tonight. "Billie came down with heavy, heavy dehydration; it was like severe dehydration, influenza, and it was just a really, really bad situation," Dirnt told MTV. "He woke up in the morning and it was bad. Let's put it this way, if you're in your hotel room and you're vomiting profusely, it's not fun. So what are you gonna do? It's hard to sing while you're puking." As for tonight's show, Dirnt added: "We're ready to rock, we're gonna be here, we're gonna have a good time."
