Britney's possibly releasing a compilation this fall to coincide with her X Factor gig.
Although nothing's confirmed, rumor has it she's releasing an album called:
"One More Time: Unreleased, Rarities and Remixes."
Some claim it's a fan-made creation, however the album's posted on Amazon.
Hopefully this means a new single in the fall for promotion! And hey, it couldn't possibly flop as hard as the “Oops I Did It Again, The Best Of Britney Spears” compilation!
