Chris Brown's manager Mike G is suing the singer claiming he was physically assaulted, according to a report from TMZ. Mike G was hired in 2012 to rehabilitate Brown's image after the singer assaulted then-girlfriend Rihanna. Now Mike G is claiming in May, Brown lured him into a room where he repeatedly punched the manager in the face and neck, causing injuries that led to an ER visit. According to the report, Mike G believes that Brown's rage was "drug-fueled." G's lawyer Patty Glaser told TMZ attempts were made to resolve the matter in a non-public way but "Chris Brown has proven to be his own worst enemy." Representatives for Mike G and Chris Brown were not immediately available for comment.
