Britney Makes ‘Music’ With Madonna
As if their open-mouth kiss on the MTV Video Music Awards wasn’t enough, Britney Spears and Madonna have teamed up on the first single from Spears’ new album, according to her Jive Records Web site. “Me Against the Music,” which Spears debuted earlier this month at the NFL kick-off concert in Washington, D.C., will be submitted Sept. 30 to U.S. radio outlets for airplay consideration. A video for the cut premieres Oct. 13 on MTV.
Spears’ album, “Get in the Zone,” will arrive Nov. 18 and may include contributions from P. Diddy, R. Kelly and the production team the Matrix, among others. Another new song, “Breathe on Me,” was performed live during a surprise mini-concert in Las Vegas last weekend.
Billboard.com has learned Spears will tour North American arenas next year, although details have yet to be announced.
“Get in the Zone” will be the follow-up to Spears’ 2001 album “Britney,” which debuted at No. 1 on The Billboard 200 and has sold 4.2 million copies in the U.S., according to Nielsen SoundScan.
