*Prosecutors hoping to nail former Liberian president Charles Taylor for war crimes at a U.N.-backed court have asked judges to subpoena supermodel Naomi Campbell as a witness, reports the Associated Press.

In a motion filed Thursday, prosecutors say they want Campbell to testify about uncut diamonds Taylor allegedly gave to her in South Africa in 1997. They say the runway diva told prosecutors through her lawyer that she was “concerned for her safety” and “did not want to involve herself in the case.”

Prosecutors claim Taylor gave arms and ammunition to brutal rebels during Sierra Leone’s civil war in exchange for diamonds. He denies the allegations.

The prosecution is also seeking testimony from Mia Farrow, who claims Campbell told her about the alleged diamond gift.

Farrow said she and Campbell were both guests at the home of South African president Nelson Mandela, where Taylor was also visiting. She said Campbell described in detail a middle of the night visit from two of Taylor’s men.

“She said during the night, some men had knocked at her door and she, half asleep, had opened the door and it was representatives of President Charles Taylor and that they had given her a huge diamond,” Farrow told ABC News. “We were like, ‘oh my gosh.’”
