THE HAGUE, Netherlands–International supermodel Naomi Campbell will testify at the war crimes trial of former Liberian president Charles Taylor today.

Taylor’s lawyer had objected to Campbell testifying, charging that the prosecution had not provided the defense with a summary of her likely testimony. The unwilling model was subpoenaed to testify about a diamond Taylor allegedly gave Campbell following a dinner party in South Africa in 1997.

Prosecutors say that if these events are true, Taylor would be shown to have supplied arms to Sierra Leone rebels in exchange for diamonds during Sierra Leone’s 1992-2002 civil war.
