Catherine Zeta-Jones gave more than three hours of emotional testimony Wednesday at a preliminary hearing to determine whether her accused stalker, Dawnette Knight, should stand trial. The Oscar winner claims Knight sent her numerous letters containing death threats. In one note, Knight allegedly threatened to "slice her up like meat on a bone and feed her to the dogs." Zeta-Jones' hubby, Michael Douglas, also took the stand, saying he was "shocked, scared and stunned" after learning that his wife was "a marked person." If convicted, Knight faces up to 19 years in prison.
