Ananova:

A rap by Britney Spears is about to be released in the US.

A Boston DJ called Clinton Sparks has put her on an underground compilation mix CD reports Radio 1.

He reckons despite her label not being happy about it, he's going to try and persuade her to do more.

"Obviously she has a lot to say. She's been involved in a lot of controversy. If she wants to address that and say stuff right there on the mix tape, because that's what mix tapes are about."

Britney's latest single My Prerogative will be released in the UK in November.
