"On November 23rd the Unplugged Acoustic album comes out!" Bieber tweeted. "Taking it back to how we started."
While no details surrounding the acoustic album have been officially announced, Bieber wrote last week that the set would include a "new song I cut in Hawaii for the holidays," as well as stripped-down versions of his previous material.
The news preceded Monday morning's (Oct. 25) unveiling of the first teaser video for Bieber's upcoming 3D biopic, "Never Say Never." The 19-second clip features footage of Bieber onstage and soundbites from Usher and his fans.
Bieber, who wrapped up the Canadian leg of his My World tour on Sunday night, resumes his U.S. run at Los Angeles' Staples Center on Monday.
