Britney Spears has moved the release date of her new Jive album, "Blackout," from Nov. 13 to Oct. 30 due to widespread leaks of the new material.

"The label is doing everything possible to prevent and avoid any further illegal distribution of songs including moving up the release date of the album," reads a statement from Jive.

The label claims some of the leaks constitute "unfinished material and demos," as well as actual album versions of songs from "Blackout."

A track list has yet to be announced, but "Blackout" is known to include the songs "Heaven on Earth," "Radar," "Piece of Me" and "Break the Ice." Among the production and songwriting collaborators are Bloodshy & Avant, Nate "Danjahandz" Hills and Kara DioGuardi.
