Childish Gambino went off on Lupe Fiasco on Twitter on July 27th over comments Lupe made about how he "don't work with blacks."  Lupe made the statement in response to a Twitter user inquiring about a possible collaboration between himself and Gambino.  After Lupe's reply, another Twitter user pointed out that he "just did a song with Wale" to which Lupe responded, "Those were niggaz. Blacks and niggaz come from 2 completely different parts of the chicken."

Gambino was obviously offended by Lupe's words and lashed out on Twitter, threatening to "smack him" when he sees him.  Peep the tweets above.
