Naomi Campbell's Blood Diamonds Story is a Lie

Mia Farrow took to the stand Monday in the war-crimes trial of former Liberian president Charles Taylor and disputed Naomi Campbell's sworn testimony from last week about whether so-called "blood diamonds" Campbell received as a gift more than a decade ago had come from Taylor.

Campbell, 40, admitted last week that she received uncut stones from two men in South Africa in 1997 but said she didn't know they were diamonds or that they were linked to Taylor.

Farrow, 65, said Monday that Campbell in fact boasted that the gift was from Taylor at a breakfast the next day as both women prepared for a charity event with Nelson Mandela, Britain's Telegraph reported.
