Oh my gosh ya'll, I think the world may be coming to an end!  It has long been speculated that Nicki Minaj may be doing a collaboration with Britney, especially since she will be the opening act for the Femme Fatale Tour.  This has finally been proven correct, and not only that, but Ke$ha also makes an appearance.  Britney's 'Till the World Ends' has had longevity that most of her other singles have never had, so this could have not come at a better time.  The remix begins with Nicki doing her thing, lettin' the words fly.  There is no better rapper out there right now, and I absolutely love everything she does - "It's Britney, Beeeeeetttttcchhhhh!!!"  Ke$ha appears on the chorus, and while it definitely doesn't flow as well as Britney's vocals, it's still interesting to see what the song would have sounded like if she had recorded it.  If you don't already know, Ke$ha actually wrote 'Till the World Ends' specifically for Britney.  The song also has a sick dubstep breakdown in the middle, contributing to an already perfect song.  This is going to be a #1 smash for sure.
