Rocker Kid Rock and rapper Eminem have been offered one million dollars to perform at a rap battle in Detroit by the producers of the upcoming documentary Rap Therapy.

The winner of the battle will be given one million dollars to be donated to the charity of their choice.

“It will be a televised rap battle and the winner will pick up GBP 500,000 for the charity of his choice,” Black Le Vine, the rap therapist explained.

There is still no word yet on if the two have accepted the offer or not.

Rap Therapy will feature appearances by 50 Cent, P Diddy, Tom Cruise, and others; the documentary will focus on the use of Hip-Hop as a tool for helping combat abuse and gang violence.
