Supermodel Naomi Campbell, so often embroiled in controversy, has found herself in the midst of yet another scandal.

The UK model has refused to give evidence in a tribunal investigating war crimes of Charles Taylor, the former Liberian dictator. Campbell refused to be drawn into discussions over whether she was the recipient of an uncut, or ‘blood diamond’, back in 1997 when she and was visiting South Africa.

Both the British supermodel and the Liberian genocidal warlord were guests of the South African President Nelson Mandela, who at the time also hosted Mia Farrow, who was campaigning to bring world attention to the atrocities that were occurring on the border between Liberian and Sierra Leone. It was widely believed that the terror campaign carried out by Taylor’s forces was funded by the sales of diamonds.

Farrow told US reporters that she learned of the gift over breakfast one morning, after Campbell had told of the previous evening where men knocked on her door and claimed that they were representing President Charles Taylor. They then gave Campbell a huge diamond.

Taylor is currently on trail at The Hague, where some 50 former victims are planning on giving evidence that he was in South Africa with the purpose of buying weapons using diamonds. They claim the Farrow story about Campbell adds further proof to the rumours.

Campbell, who was recently approached on the subject during a benefit show to raise money for Haiti, refused to comment other than saying she did not receive any diamonds, just before she slammed the camera against the floor.
