Georgia-bred rapper 2 Chainz was reportedly arrested at New York's La Guardia airport Tuesday when authorities discovered a set of brass knuckles in the rapper's carry-on bag.  The rapper, whose real name is Tauheed Epps, was taken into custody and charged with a misdemeanor weapon charge, putting a scheduled performance in Raleigh, North Carolina in jeopardy.  No word on whether he made the show.  Interestingly, 2 Chainz's G.O.O.D. Music compatriot Big Sean took to Twitter to defend his colleague, saying that what was found was a "4 finger ring that spelled hood. We had a shoot yesturday n he was rockin em."
