Last week, it was John Edwards mistress Rielle Hunter answering questions from Oprah Winfrey about a "Nightline" story. Yesterday, it was supermodel Naomi Campbell on Oprah's couch talking about us — specifically, this report from Brian Ross and his investigative unit about claims she received a blood diamond from former Liberian president Charles Taylor, a man currently on trial for war crimes. Actress Mia Farrow told us — and prosecutors — that the supermodel famous for her hot temper talked about receiving the gift in the middle of the night from Taylor's men during a shared 1997 visit to former South African president Nelson Mandela. Asked why she refuses to talk to prosecutors, she told Winfrey: "I don't want to be involved in this man's case — he has done some terrible things and I don't want to put my family in danger." Campbell also said that "a sound effect" had been added to an ABC News interview conducted during Fashion Week — embedded below — that ended with her refusal to take questions on the topic and slapping a camera as she stormed off. That's just not true. Click HERE for the original report, "Brian Ross Investigates: Blood Diamond."
