The ongoing war of words between singer and rapper Chris Brown and former B2K member Raz-B shows no signs of slowing down. The two engaged in a homophobic Twitter war back in December 2010 that became so heated it even led to Brown receiving a death threat. But Raz-B is now upping the ante in his upcoming memoir. This Boy's Life, due to be released in September, accuses Brown of being gay and a drug addict. "I've never had issues with substances; even when I was at my lowest," writes Raz-B. "I always thank God I never had a serious addiction like the Weezy's [Lil Wayne] and the Breezy's [Chris Brown]." Breezy, meanwhile, continued his foot-in-mouth on Twitter syndrome by venting at the accusations before taking down the posts. But since he has over nine million followers, those briefly-posted comments have circulated fast. "Lying about somebody in a book is called defamation of character," he tweeted. "Keep feeding people bull**** and ima end up owning you and that book! RAZ B! God bless... My lawyers are handling it! Lol ima chill!" While Brown is still moving forward with his lawsuit plans, neither one of them is coming out looking too good in this battle. Time to kiss and make up?
