Green Day posted on their official site that it has put away the sunscreen and is hard at work on a brand new (and already hotly anticipated) album. And while additional details remain scarce, a spokesperson for the band's label, Reprise Records, did confirm to MTV that writing is underway at an undisclosed studio in California's East Bay area. The spokesperson went on to note that it is still very early in the recording process, and that Green Day have not settled on a producer, title or release date for the new album.

With Monday's announcement, it appears that official business has, uh, officially begun on the new album. And while it remains to be seen just how Green Day plan on following up American Idiot -- an album that sold more than 5 million copies in the U.S. and won the Grammy for Best Rock Album -- the band promised a full update on the new record would be posted on its Web site next week.
