The fountain of endless controversy that is Chris Brown continues its proud, powerful flow. The R&B singer posted a photo on Twitter Wednesday night of him and his friends in their Halloween costumes. They were terrorists. "Ain't nobody F--king wit my clique!!!!#ohb," Brown eloquently captioned the logic-defying photo. While the world uttered its collective "WTF," Brown's mother defended her son's arguably (though not really) offensive costume, tweeting, "HALLOWEEN IS FOR FUN NOTHING MORE THAN JUST FUN. GET A LIFE PLEASE." Duly noted.
