NEW YORK -- Is Justin Timberlake bringing his music career back?

The 31-year-old superstar has concentrated almost exclusively on his acting career over the last few years. But on Thursday, he posted a video on his website that showed him walking into a studio, putting on headphones and saying: "I'm ready."

Timberlake hasn't made an album since 2006's Grammy-winning "FutureSex/LoveSounds." In the video, Timberlake is also heard saying that he obsesses over his music and doesn't want to put music out that he doesn't love -- and that you have to wait for music you love.

The video ends with a countdown to midnight Sunday.

Timberlake -- who recently married longtime girlfriend Jessica Biel -- has been in several movies, including "The Social Network," "Bad Teacher," "Friends With Benefits" and last year's "Trouble With the Curve."

"FutureSex/LoveSounds," which won four Grammy Awards, launched three No. 1 hits and sold more than 4 million units in the United States.
