Miranda Lambert is officially in a celebrity feud with Chris Brown.  The "Official Celebrity Feud" was proclaimed yesterday by "Good Morning America."  The two have been tweeting back and forth at each other.  You might recall last week after the Grammys, Miranda had a few things to say about all the publicity Brown got on the award show and his alleged attack on former girlfriend and R&B singer, Rihanna.  Miranda also held up a sign at one of her concerts over the weekend saying, "Take Notes Chris Brown," in which she followed up with her song "Gunpowder & Lead."   Brown has responded by saying things like, "Hate all you want because I got a Grammy now!"  Miranda responded to that with, "Oh and one more thing for all who are asking...I have a Grammy too."  The feud is ongoing on Twitter.
