Supermodel Naomi Campbell is headed to court...again.

The notorious diva, 40, has been subpoenaed by judges trying the case of former Liberian President Charles Taylor, whom they believe gave Campbell a blood diamond in 1997 at a party hosted by former President Nelson Mandela.

The catwalk queen had repeatedly refused to participate in questioning when they first asked for her cooperation.

In April, Campbell grew visibly agitated when asked about receiving a "huge," uncut "blood diamond" from the dictator.

"I didn't receive a blood diamond and I'm not going to speak about that," Campbell snapped before storming off and punching the camera in the producer's hands.

Prosecutors believe Taylor was lying when he said he never owned any rough diamonds, and they are charging him with 11 counts of war crimes and crimes against humanity.
