Britney Spears ft. Nicki Minaj & Ke$ha "Till The World Ends (The Femme Fatale Remix)" Song Premiere

For her latest remix, Britney Spears has taken "Till The World Ends", the second single off her new album Femme Fatale, & added her upcoming tourmate Nicki Minaj & the song's writer Ke$ha to the mix. As is the case with the entirety of Femme Fatale--but to a greater degree, this song has really grown on me & now, with the remix, I'm in love! Random thought: Who thinks Ke$ha's vocals came straight off the demo?! lol
