When we last checked in on Mos Def, he was doing comedy.
But we don't think the artist now known as Yasiin Bey was joking when he just dropped a video in which he challenged anybody in the game to battle him.
Me, Black Thought and King Los vs. anybody," Def said "Red Bull Music Academy, put up a mil on that and we’ll give our winnings to charity and take your money, too. Tired of these dudes pretending like they dope ... The dope niggas who think they dope ain't as dope as you think ... …We don’t have to do make no back and forth corny records about it, we can put it on its feet for the world to see."
Not long after the video hit the web, Lupe Fiasco declared himself Def's huckleberry.
Mos Def vs. Lupe? Who you got?
Update: Mos Def backs down.
