What happens Britney Spears and Ke$ha team up? The result is almost apocalyptic. Britney's new tune, "Till The World Ends," is co-written by pop's party queen, and is the second release from her upcoming album Femme Fatale.

The Max Martin and Dr. Luke produced track definitely has more than its fair share of Ke$ha-isms, and recalls "Your Love Is My Drug" and "We R Who We R," amongst others. "That song is me imagining her and any female musician touring the world," she told Spin. "You know, when you go out, and you're having an amazing, magical night and you don't want to go to sleep and you want it to last until the world ends."

The single was posted by Perez Hilton's website on March 2; however, it will not be officially released until March 14, and the album is set to drop March 22. In the interim, the song is sure to be found on a dancefloor near you. Take a listen below:
