Justin Timberlake: "I'm ready" to release new music

It looks as if  Justin Timberlake is ready to bring 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.

"I'm the one who sits and is obsessive about it before you even get to hear it," he explained. "I don't want to put anything out that I feel like is something I don't love. You just don't get that every day. You have to wait for it."

The video ends with a countdown to midnight Sunday.

According to The New York Times, "several people with direct knowledge of Mr. Timberlake and his plans" said the countdown will lead to the release of a new song featuring Jay-Z and Beyonce.

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.
