Safe to say this country crooner is not a fan of the controversial hip-hop star. After last year's Chris Brown Grammy lovefest just three years after his infamous assault on Rihanna, Blake Shelton's other half took to Twitter to slam the singer. "Strange. And Chris Brown twice? I don't get it. He beat on a girl…, she wrote. "Not cool that we act like that didn't happen." She continued her anti-Chris campaign at her concert shortly after, holding up a sign that read "Take Notes, Chris Brown" before singing "Gunpowder and Lead," a song about a woman preparing to kill her abusive ex-husband.
