The woman, identified only by her first name Shahla, was accused of killing Leila Saharkhizan, the wife of Irans football star Nasser Mohammad-Khani in Tehran in October 2002.
According to the prosecutors, Shahla befriended Mohammad-Khani and the footballer took her as his second wife. Irans Islamic legal system allows polygamy. The prosecutors said Shahla was so jealous of Mohammad-Khanis other wife that she eventually killed her. Shahla denied the accusation and proclaimed her innocence throughout the trial.
A panel of five judges in the SSC ruled against Shahla, upholding a sentence which had already been seen to by a smaller panel in the court earlier this month.
She faces imminent execution.
