The Olympic star accused of killing his girlfriend broke down in tears as formal charges against him were read in court Friday. Prosecutors say the murder was premeditated.

South African media reported that Pistorius is accused of shooting his girlfriend, Reeva Steenkamp, four times through a bathroom door. Steenkamp was a model who has a reality TV show debuting this weekend on South African television.

According to a CNN reporter who was in the courtroom, Pistorius sat down and put his head in his hands after the charges were read in court. Within minutes, Pistorius' whole body was shaking uncontrollably, and he was sobbing.

The court has postponed Pistorius' bail hearing until Tuesday. He will remain in custody until then.

Pistorius is a double-amputee who gained worldwide fame and inspired many last summer when he became the first runner to compete in the Olympics on carbon-fiber legs.
