BRITNEY Spears has admitted her latest single Work Bitch is inspired by the writings of Karl Marx.

The star has based her latest hit on a lifetime’s study of the father of communism, and a strong desire to champion the cause of the proletariat.

She said: “I’ve always sung about the relationship between people and the economic systems which govern their lives, for example my exploration of the seductive power of capital in Gimme More.

Work Bitch is a satire of commodity fetishism which underlines that the real owners of the means of production are the workers themselves.

“When I whip a woman wearing bondage gear in the video, its a metaphor.”
