"To whom it may concern . . . I think I'm READY!" Timberlake tweeted, alongside a link to a video on his website, in which he explains his decision to return to music after focusing on his acting career for several years.
The 31-year-old star of "The Social Network" and "Bad Teacher" is seen in the online clip walking into a recording studio.
"Someone asked me the other day... 'So are you just done with music?'" Timberlake said.
"[Music] means more to me than anybody else in the world. I've only done two albums in the past decade," he said. "What does the next decade mean to me? I don't want to put anything out that is... something I don't love. You just don't get that every day. You have to wait for it."
UsMagazine.com quoted an unnamed source as saying Timberlake is nearly done with the album, however, no release date has been announced yet.
