Pop singer Britney Spears links with her tourmate Nicki Minaj on the official remix to “Till the World Ends,” which also features Ke$ha, who happens to be the song’s writer.

Nicki Minaj delivers her usual killer verse, “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.”
