Britney Spears Latest Song: 'Till The World Ends' Remix Leaks: Britney Spears isn't the only pop titan dancing until the world ends: Nicki Minaj and Ke$ha have joined forces to add a new spin on an all-female remix of Femme Fatale's second single, "Till the World Ends."

The reworked dance anthem, which leaked online Friday (April 22), appears to have surfaced earlier than expected as noted by a series of countdowns on all three of the stars' websites. Mixing the dance tune's original sonic swirls with heavier bass, Britney tourmate Minaj starts off the remix by throwing down an aggressive verse, in which she calls out a female hater: "A-A-A-A-A-AYE!/ Chimpanzees is hatin', but I take it all in stride/ Put her in a jungle with bananas on the side/ Told you they'd revive your career, but somebody lied/ I ain't talkin' poultry when I say this chicken's fried.

After Minaj spits a few introductory bars, Spears delivers the song's first verse before an introduction for the all-star trio. "It's Britney, bitch. I'm Nicki Minaj and that's Ke$ha!" the Young Money MC proclaims.

Ke$ha, who originally wrote the track for the pop princess, takes part in singing the club-ready track's chorus. Spears soon takes back control of the song as Ke$ha shadows the singer's lines toward the end of the second verse and bridge. Unlike the original version, the "Till the World Ends" remix also features a stuttering dubstep dance break. News of a star-studded collaboration was hinted earlier this week when producer Dr. Luke tweeted, "NICKIMINAJ killed it tonight!!!! thanks!!!"
