Britney Spears' comeback: The inside scoop

The first single from Britney Spears’ long-awaited fifth studio album will debut as soon as next week, EW.com has learned — and it’s not this or this, the two supposed Britney tracks that leaked online at perezhilton.com last week.

A source who’s heard the single says it’s called ”Gimme More,” an up-tempo club cut produced by Timbaland protégé Nate ”Danjahandz” Hills (Justin Timberlake, T.I.). ”Gimme More” was also reported as the name of the music video that Spears was spotted shooting in July. (Representatives for Jive, Spears’ label, did not return calls seeking comment.)

”People are going to love [the new single],” raved the source. ”It’s like when Justin came back [with FutureSex/LoveSounds] — she’s got a whole new sound. She’s funky.”

Another insider who’s heard ”Gimme More” is similarly enthusiastic: ”It’s a smash! She’s going to come out strong. The only question is, with all the drama, are people going to want something fun or something more serious? This is a dance single.”

Spears also worked with other producers on material for her upcoming CD, including J.R. Rotem (Sean Kingston), and although the album still has no official title or release date, a third source close to the top-secret project says it’s expected to hit shelves this fall with little to no promotional setup: ”She’s got more than enough material.”
