Guess Britney Spears just can't get enough of Madonna. They'll be putting their mouths together again when they sing a duet of Spears' new song, ''Me Against the Music,'' the first single from her forthcoming album, which finally has a title, ''Get in the Zone,'' Spears' label, Jive Records, announced Tuesday. Fans who saw Spears' performance at the NFL season kickoff special two weeks ago, as well as the handful who saw her unannounced striptease performance over the weekend in Las Vegas, have already heard Spears' solo version of the tune. Cowritten by Spears and produced by RedZone, ''Me Against the Music'' will ship to radio on Sept. 30 and see its video debut on MTV's ''Making the Video'' on Oct. 13.
Other collaborators on the album, seven of whose 13 songs Spears cowrote, will include such songwriters and producers as Moby (''Early Mornin'''), Bloodshy & Avant (''Showdown''), Guy Sigsworth (''Everytime''), and R. Kelly (''Outrageous''). It's not clear whether some other recent tracks Spears has recorded, including ''The Answer'' (with P. Diddy) and "Shadow'' (with The Matrix), will also appear on the new disc. ''Get in the Zone'' is being released a week ahead of schedule, on Nov. 18.
