AceShowbiz - Supermodel Naomi Campbell will testify in the ongoing war crimes trial against former Liberian president Charles Taylor in August after postponing her original court date. The British beauty became embroiled in the high profile case in The Hague after it was alleged Taylor had given her a blood diamond as a gift at a party in 1997.

She has previously refused to comment on the allegations and, during a recent televised chat with Oprah Winfrey, she insisted she had no idea who Taylor was when she met him at a gathering hosted by then-South African president Nelson Mandela, her friend.

Campbell has also voiced her fears for her own safety and that of her family if she appears as a witness and testifies against Taylor, who has pleaded not guilty to 11 charges, including murder, torture, rape, sexual slavery and the use of child soldiers and terrorism during Sierra Leone's 1991-2002 civil war.

Prosecutors subpoenaed Campbell, claiming her testimony would provide "direct evidence of the accused's possession of rough diamonds". She was initially due to testify in the Netherlands on July 29 but the model recently requested a later hearing and a new date has now been set for August 5. The model faces jail time if she fails to appear in court.
