Britney Spears has unveiled the tracklisting to her much-anticipated new album, BLACKOUT, after learning a German website had all the details and was leaking news online. The pop star's record label Jive released the album's song titles and the cover art on Friday (12Oct07). The artwork features a raven-haired Britney scowling into the camera, wearing a tattered white fedora and a sheer pink gown - in front of an abstract maze-like background. Meanwhile, the tracks included on the album, which is scheduled to hit stores on 30 October (07), include new single Gimme More, Perfect Lover, Hot As Ice, Naked (I Got A Plan) and Pharrell Williams duet Why Should I Be Sad, which the hip-hop star also wrote and co-produced. Top new producer Nate `Danjahandz' Hills produced four of the album's 12 tracks. Bloodshy + Avant produced another four tracks and in-demand hitmaker Kara DioGuardi produced one tune, Heaven and Earth.
