Naomi Campbell swats ABC News camera

"I never received a diamond and I'm not going to speak about that -- thank you very much," said Campbell.

Campbell was upset when asked if former Liberian President Charles Taylor gave her one of the diamonds he's accused of using to fund a campaign of terror in Western Africa.

Taylor is on trial for crimes against humanity.

Campbell has refused to be interviewed by a special United Nations team leading the investigation against Taylor.
