Miranda Lambert blasts Chris Brown in concert VIDEO

 Miranda Lambert blasted Chris Brown in concert!

The battle began last week, after Miranda ondered on Twitter why the convicted felon was featured on not one, but two performances during the Grammy Awards.

She tweeted:  "Chris Brown twice? I don’t get it. He beat on a girl," before adding "Not cool that we act like that didn’t happen. He needs to listen to Gunpowder and lead and be put back in his place. Not at the Grammys."

Chris Brown fired back on Tuesday, via Twitter when he wrote, "Hate all u (you) want becuz (because) I got a Grammy now! That's the ultimate f**k off! I'm back so watch my back as I walk away from all this negativity."

Days later, during a concert in Massachusetts, Miranda pulled a poster out of the audience reading "Take Notes Chris Brown."

She told the audience:  "Get a good picture now, put it on Twitter,"  while holding the poster up.

Miranda added, "I’ve been in a world of hurt with Chris Brown fans lately ... but see, I just have to speak my mind because where I come from beating up on a woman is never okay.”

 "So that's why my daddy taught me early on in life how to use a shotgun." The crowd went wild.
