Chris Brown is facing a $50 million lawsuit stemming from an alleged violent incident backstage at his concert last Friday. The suit, filed today in Harris County, Texas, names Brown, his tour promoter Live Nation, and associates Sinko Ceej, Hood Boss, and Yella Beezy as defendants. The plaintiffs—Larry Parker, Joseph Lewis, Charles Bush, and Da Marcus Powell—are also seeking a temporary restraining order against all defendants.
