EXCLUSIVE: The family of Nicole Brown is demanding a retraction and correction to assertions made by Vanessa Grigoriadis in her article published by New York magazine chronicling the O.J. Simpson book debacle and subsequent fall of Judith Regan at News Corp.'s HarperCollins. In a faxed letter to New York magazine owner Bruce Wasserstein obtained by FishbowlNY, attorneys for Denise Brown and Nicole Brown's family claim that the article contains "blatant and intentional factual misrepresentations" about the Brown family's involvement in News Corp.'s attempts to offer them payout profits from the ill-fated If I Did It book project.
