Following Chris Brown’s two GRAMMY performances and his GRAMMY win, Twitter was buzzing with negative banter about the singer.  Brown took to Twitter to address all the haters and answered back in a series of angry and profane messages.  Brown declared in one post, which has since been deleted but saved in a screengrab on the website Mashable, "HATE ALL U WANT BECUZ I GOT A GRAMMY Now! That's the ultimate F--K OFF!"  Breezy returned to the GRAMMY stage on Sunday night for the first time since his 2009 felony assault on ex-girlfriend Rihanna.  Given his scandal-plagued image, Brown generated a record number of tweets during his return to the GRAMMY stage. He drew 453-thosuand social media comments over a five-minute span, according to Bluefin Labs' numbers. Adele, who swept the awards, spurred the most commentary, however, with 489-thosuand when she won Album of the Year near the end of the telecast.
