Britney Spears May Release ‘Till the World Ends’ as Next Single, Written by Kesha

Britney Spears' new album, 'Femme Fatale,' isn't out until the end of the month, but the 'Hold It Against' me pop icon could be set to release a second single -- 'Till the World Ends,' written by Kesha -- as early as next week.

"Hearing from Jive Records that we'll have a new @BritneySpears single to play next week," Tampa radio station 93.3 tweeted Monday.

Fans speculate that the anticipated new Spears song will be Kesha-written 'Till the World Ends,' because the single artwork has already leaked to the web.

Britney's manager, Larry Rudolph, commented on the release of the upcoming single, but didn't spare any telling details -- other than to pump up the fans with his own excitement. "I don't think I've been this excited about releasing a Britney single in many, many years. It's that good. That's all I'm gonna say about it at the moment," Rudolph tells MTV News.

"I haven't heard a final mix of it, but I should get it in the next day or two," he adds. "So far, what I've heard is just extraordinary. It really is amazing. Her fans will be very happy with it. I'm trying hard to get it out before the album comes out."

Kesha dished on 'Till the World Ends' specifically, but didn't mention anything about it being a radio release. "That song is me imagining her and any female musician touring the world," she tells Spin of the potential single, produced by Dr. Luke and Max Martin. "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."

Oh, we know -- but what we don't know for sure is whether 'Till the World Ends' will be the Brit-Brit single to drop next week. Stay tuned!
