The Beat: Green Day's Album Trilogy, 2NE1 Tops K-Pop

Green Day have been dancing around heading into the studio and cutting the follow-up to 2009's "21st Century Breakdown" for quite some time, but on Tuesday (Feb. 14), frontman Billie Joe Armstrong announced via Twitter that the trio has begun recording a new full-length.

"Happy Valantine's day! Officially started recording the new record today. It's FUCK TIME!!!!" Armstrong posted. No word whether or not "FUCK TIME!!!!" is the title of Green Day's ninth studio album, but here's hoping!

Last May, Armstrong announced that there were a "ton of new songs" ready to go for a new album, and the group previewed a few of those new cuts at a secret California show in August. "21st Century Breakdown," which won a Grammy Award for Best Rock Album, has sold 1 million copies since its May 2009 release, according to Nielsen SoundScan.

Meanwhile, "American Idiot," the stage musical inspired by Green Day's 2004 album of the same name, is currently inhabiting the Oriental Theatre in Chicago and will end its U.S. run in San Francisco on July 8.
