Rapping With The Stars?

I read in TVSquad, and in XXL, that MTV is planning on launching a ‘Dancing With The Stars’ type show called ‘Rapping With The Stars’. Now I would like to know the logic behind this show, since not many details are out, dancing is a 2-person activity, rapping is generally more of a 1 activity thing (not counting working with a producer, or a rapping duo), so the execution of such a show is already looking suspect. This will be amusing (kind of like the White Rapper Show), or disastrous (ie having the Ying Yang Twins or Youngbloodz as the stars).
