Britney Spears' newest single 'Till the World Ends' has leaked to Web, and this time around, Ms. Spears has teamed up with fellow pop songstress Kesha, who penned the pulse-pounding song.

Upon first listening 'Till the World Ends,' one can't help wanting to know all of the words immediately. Like Britney's last hit 'Hold It Against Me,' 'Till the World Ends' has an infectious, fast-paced dance beat and insanely catchy vocals that leave you panting as you try to keep up.

"I notice that you got it / You notice that I want it / You know that I can take it to the next level ba-by / If you want this good s--- / Sicker than the remix / Baby let me blow your mind tonight," Britney sings in the first verse.

'Till the World Ends' is packed with plenty of synth and a chorus featuring lots "woah woah's" that is sure to get everybody chanting along with the pop songstress. Like many of her other songs, the lyrics are all about finding a suitable partner and dancing until your legs give out or, in this specific case, 'till the world ends.'

'Till the World Ends' will be featured on Spears' upcoming album, 'Femme Fatale,' in stores March 25.
