Mos Def Arrested and Kicked Out of South Africa for Having Bad Papers

Mos Def allegedly tried to use a "world passport" Thursday to leave South Africa, but since there is no such thing as a "world passport" ... he was arrested and banned from the country for five years.

A Department of Home Affairs spokesman in S.A. tells us Mos overstayed his visitor's permit, but he can apply for permanent residency if he wishes ... he just needs to go through the proper channels.
