Miranda Lambert was serious when she posted to her Twitter account, following the 2012 Grammy Awards, that she thought Chris Brown should listen to her song, "Gunpowder and Lead."
At a performance Thursday in Amherst, Massachusetts, Lambert held up a fan-made sign encouraging the 22-year-old R&B singer to pay close attention to the track, which focuses on a woman who grabs her gun as defense against an abusive husband. The sign Lambert held read, "Take notes Chris Brown."
Lambert told the cheering audience, "I just have to speak my mind, because where I come from, beating up on a woman is never OK. So that's why my daddy taught me early on in life how to use a shotgun."
In 2009, Brown pleaded guilty to one count of assault in the domestic disturbance that involved his then-girlfriend, Rihanna, the night before the Grammy Awards.
The singer - whose Twitter account was the subject of controversy earlier this month, when he used it to respond to those critical of his appearance at the Grammy Awards on February 12 - seemed to respond to Lambert's performance on Saturday.
"Using my name to get publicity? I love it! Perform your heart out!" he tweeted, following it up with, "Go buy @miranda_lambert album! So motivational and "PERFECT"!"
The singer's tweets also inspired a series of reports when he wrote early Monday, "Happy Birthday Robyn!"
Robyn, of course, is Rihanna's first name - and February 20 is her 24th birthday. She replied with a simple thanks, but the exchange has drawn a healthy amount of buzz.
