The lawsuit names Courtney Burgess, a one-time music industry bit player, his lawyer and the owner of the cable network NewsNation, which aired an interview with Mr. Burgess.

Combs' lawyer says Courtney Burgess, who said he has videos showing Combs sexually assaulting minors and celebrities, is spreading "outrageous lies."

Sean “Diddy” Combs has filed a $50 million defamation lawsuit against a man who publicly claimed to have videos depicting the mogul sexually assaulting inebriated celebrities and minors, which his lawyers say could negatively influence his upcoming trial.
