Team Britney would do some BS like that. Adding Ooh La Flop, Work Work, Perfume, S&S.
But nah. Larry said it was 80% done back in February, we know Britney works fast. Plus she teased "soon... very soon" in her last interview regarding an album so it adds up to be her.
Doesn't make sense for Beyoncè to do one. Unless it's a HIStory tea.
