Things allegedly turned bad last month, but Mike G claims without provocation, Brown took him in a room, brutally attacked him with repeated punches to the face and neck, which landed him in the ER.

The lawsuit claims Brown, rather than being remorseful, began mocking Mike G on social media and bragging to friends about the beating. Mike G says Brown had the audacity to tell people working on his tour, if they got out of line he'd beat them just like he beat Mike G.

Mike G says Brown's rage was drug-fueled and the suit mention concern for retaliation from Brown's "gang member friends."
Mike G's attorney, Patty Glaser, tells TMZ, "We did everything we could to resolve this in a non-public way to avoid damage to Chris Brown. Regrettably, as outlined in our complaint, Chris Brown has proven to be his own worst enemy."



Update:

11:00 AM PT: Chris just responded to the lawsuit in an Instagram video, claiming he fired Mike G for stealing money from him. Mike G's lawyer says that's not true and they will be adding a defamation claim to the lawsuit.
