The former girlfriend of South African hip-hop star Nkululeko Habedi, known as Flabba, has pleaded not guilty to his murder.
Sindisiwe Manqele, 26, claims she killed Mr Habedi in self-defence at his home in Alexandra, Johannesburg.
Earlier this year, Ms Manqele applied for bail showing what she claimed to be defence wounds on her stomach and wrists.
Mr Habedi was a member of the award-winning group Skwatta Kamp.
The prosecution has opened its case in the Randburg High Court by calling Luyanda Sulupa, a cousin of the deceased who was at home on the night Mr Habedi died in March.
He has been giving testimony that he heard the two arguing for some time when she emerged from their room crying and asking for help.
“I sheltered her, thinking Flabba would come out, he didn’t. I asked her: ‘What help do you want?’ She said: ‘I stabbed your brother’,” Mr Sulupa told the court.
The 38-year-old was stabbed once in the heart and died shortly after.
Prosecutors say they can prove that Ms Manqele’s wounds were self-inflicted and that she killed the 38-year old unlawfully – allegations she has denied.
Ms Manqele is out on bail of $720 (£470). BBC
