Check out this first listen of Britney Spears‘ new song “Till The World Ends” (rumored to be her second single)!

The track was written by pop phenom Ke$ha and produced by super producers Dr. Luke, Max Martin, and Billboard. The full song is expected to be released March 14 with the full album Femme Fatale dropping March 29.

“Till The World Ends” was JustJared.com’s favorite song (hands down!) when previewed Brit Brit’s album earlier this year. It’s sooooooooooo infectious and the “Oh oh oh oh oh ohs” have been stuck in our head since the first time we heard it.
