Britney's back (again)--this time courtesy of a sexy new Instagram video.
The formerly pig-tailed schoolgirl of our '90s dreams just dropped a steamy clip on Instagram, and it's shrouded in plenty of mysterious sex appeal.

What we do know is that Britney looks pretty lonely performing to an audience of zero. But if she wants some company...well, you know where to find us.
