The singer's comments were allegedly sparked by Raz-B's remarks via his own page on the social networking site which stated that he was "thinking how can n***as like [Eric Benét] and [Chris Brown] disrespect women as intelligent as Halle Berry, Rihanna".
Brown immediately replied: "N***a you want attention! Grow up n***a!!! D**k in da booty ass lil boy.
"Tell me this!! Why when the money was coming in you won't complaining about getting butplugged! When I need tips on how to demolish my career I'll call ya!!!!! (sic)"
The comments were thought to be a reference to Raz-B's previous claims that he was molested by B2K's manager during the height of the band's fame, reports TMZ.
Brown continued the attack but later insisted that he is "not homophobic" and that his comments were made specifically because he finds Raz-B to be "just disrespectful".
"BTW... I love all my gay fans and this immature act is not targeted at you!!!!" he added.
