Chris Willman Senior Music Writer and Chief Music Critic Sean Combs has been sued in federal court by Casandra Ventura, who once recorded for his Bad Boy label as Cassie, with the singer alleging that the music mogul raped and beat her over a period of a decade. In response, Combs’ team is characterizing the suit as the result of an unsuccessful shakedown attempt by a former girlfriend. The suit was filed in the United States District Court for the Southern District of New York.
