Ke$ha Co-writes Britney Spears' New Single 'Till The World Ends'

NEW YORK (Top40 Charts) Britney Spears' new single, "Till the World Ends" is dance-floor track, reportedly produced by Max Martin and Dr. Luke and co-written by Ke$ha.
It actually has a Ke$ha-esque party vibe with Brit Brit challenging fans to 'Keep on dancin' till the world ends.'

"I consider myself a songwriter before and above everything else, so it's an honor to write for one of pop music's biggest icons.
And I hope it gets everyone's ass on the dance floor cuz y'all know that's what K-Monay does best!" the singer said.

Last month according to SPIN, Ke$ha said about this new song:
"It's about the power of an artist performing a great gig. That song is me imagining her and any female musician touring the world.
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."

This new track is the latest single from Britney Spears' forthcoming 'Femme Fatale,' which drops March 29, 2011.
