The war of words between singers Miranda Lambert and Chris Brown is heating up.
Lambert held up a homemade sign at her concert at the University of Massachusetts that read: "Take Notes Chris Brown", then lashed out at him from the stage.
As the crowd cheered, she added, "So that's why my daddy taught me early on in life how to use a shotgun."
Now, Brown is firing back, tweeting: "Using my name to get publicity? I love it! Perform your heart out!"
The feud started after Brown was welcomed back to the Grammys® three years after his infamous assault on Rihanna and Lambert tweeted: "I don't get it, he beat up on a girl."
Brown launched a profanity-laden tweet at Lambert: "HATE ALL U WANT BECUZ I GOT A GRAMMY Now! That's the ultimate [blank] OFF!"
To which Lambert has just tweeted back: "Oh and one more thing for all who are asking...I have a Grammy too."
