OK so I dunno what happened to the last thread, but Billboard have updated their Twiiter page:

http://twitter.com/billboardmusic

Either a new album or, more likely, a re-release of the "Circus" album.

it was posted before and it's fake

that is a fake billboard twitter account unfortunately :S, so I don't know if that information is completely true :S

I think It'll be a re-release of Circus

Fake Billboard Twitter Account.

There was another thing posted this morning, too.

I seen it, but it wasnt closed or anything. It must have been deleted because my posts were deleted.

this morning it said new britney album this summer, but then was updated for winter.

fake, but I hope a re release
