The defamation lawsuit filed in Los Angeles Superior Court on Wednesday by the reality TV stars and businesspeople is a fast and aggressive pushback against allegations they say are entirely baseless. They say Ray J, whose legal name is Ray Norwood Jr, falsely claimed that he was working with federal investigators on a racketeering case against them that will soon lead to their indictment. The lawsuit says Ray J's comments are part of a “sustained campaign of harassment and defamation” that has gone on for years. “No such federal investigation exists; no law enforcement agency has initiated any criminal proceedings or investigations related to racketeering charges against Ms. Kardashian or Ms. Jenner; and no credible evidence whatsoever supports these inflammatory allegations,” it says. Ray J is a singer, actor and brother to pop star Brandy.
