Britney Spears has taken time out of her busy rehearsal sessions for her ongoing CIRCUS tour to head back into the studio and begin work on her next album.
The pop star is currently on the European leg of her global jaunt, but she reveals she's already coming up with new tunes for a follow-up to her 2008 LP Circus.
And she's reunited with longtime collaborator Max Martin, the brains behind her hit singles Oops I Did It Again and ...Baby One More Time, during a tour stop in the producer's native Sweden.
Writing on social networking site Twitter.com on Sunday (12Jul09), she says, "In Stockholm in the studio with Max Martin."
