Chris Brown Scuffles with Raz-B on Twitter Using Ugly SlursChris Brown and Raz-B engaged in a nasty tit-for-tat of homophobic and other insensitive put-downs on Twitter this week after the former B2K singer called out Brown over the abuse incident with ex-girlfriend Rihanna.

The fight began when Raz-B (@razb2k -- real name De'Mario Monte Thornton) casually tweeted: "Im just sittin here Thinking how can n---- like @ebenet [Eric Benet] and @chrisbrown disrespect women as Intelligent as Halle Berry, Rihanna."

Soon after, it was war for Brown (@chrisbrown) and he replied with a back-and-forth exchange filled with nasty remarks, for example, calling out Raz-B for being molested as a child and mocking him for being a boy band singer. Raz-B joined in with similar comments, several times accusing Brown of being on the "down low." See the highlowlights of the heated exchange after the jump.
