Is the improbable comeback on track? Sidelining "subpoena this" and "custody battle that" talk for at least several minutes, Britney Spears on Thursday night premiered the first single off her new album at Z-100's website. "Gimme More" (which I gave a listen to in between reading stories to the moppets) kicks off with the pop tart snarling [ Earmuffs!], "It's Britney, bitch," before launching into her famous breathy vocals and a techno, dance-friendly and very catchy beat.

Spears' new album, says People, streets Nov. 13.
