U.K. trade body the BPI has partnered with iTunes on an exclusive release of the BRIT Awards duet between alt-rock act Florence and the Machine and rapper Dizzee Rascals.

The pair will perform "You Got The Dirtee Love" - a mash-up of Florence's version of "You Got The Love" and Dizzee Rascal's single "Dirtee Cash" - at the London Earls Court ceremony on Feb. 16. The event is televised live on ITV1 in the U.K.

The performance will then be mastered for release via iTunes on Feb. 17 to help raise money for the BRIT Trust, the U.K. music industry charity which benefits from proceeds from the awards.

The release of "You Got The Dirtee Love" has been arranged with the support of the artists' labels Island/Universal (Florence and the Machine) and Dirtee Stank (Dizzee Rascal).
