Yasiin Bey is charged up. Inspired, or annoyed, maybe, by the ongoing Drake vs. Meek Mill beef, the rapper formerly known as Mos Def laid down the gauntlet and challenged any rapper in the game to a battle. In a video posted on YouTube, Bey puts his foot down and takes shots at the battle records put out by Drake and Meek Mill and says he, Black Thought and King Los will take on anybody."Me, Black Thought and King Los vs. anybody," said Mighty Mos. "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. You alright but relax...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...We'll battle anyone, I don't care who you tell. That go for any set, any time. Champion sound, for real. The word is out...Let's go."

Before long, Lupe Fiasco responded to the challenge via Instagram (because really, where else would you do it?) and said he's ready to go:

Dear Yasiin Bey, Whenever, wherever, whoever... Sincerely, Lupe Fiasco
