"We as a family trying to grapple with Jabulani's death found this extremely outrageous and insensitive, to say the least," Ncana said.
He added that Sengadi and her mother returned to the deceased's home on Saturday as they had not expected HHP's father and aunts to be there.
"Ms Sengadi demanded house keys that she is not entitled to. Before arriving at the house, she had also demanded that Jabulani's domestic worker send her a picture of the medication [the helper had been administered by a doctor after she discovered the star dead in his bedroom]."
Sowetan has learnt that during the surprise visit things boiled to a heated argument between HHP's father, Robert, and Sengadi - who was reduced to tears when he refused to acknowledge her.
"For the first time, Jabu's father told Lerato and her mother to their faces: 'Jabu is my son. I know his things. Don't you think if he was married I would know? Jabu does not have a wife. Jabu was never married'," Sowetan was told.
As the family makes their way to Mmabatho, Mahikeng, for the funeral on Saturday, there will be "24-hour security at the house" to thwart any unauthorised entry.
The insider explained that the lobolo process was initiated two years ago in Soweto, but was never finalised because "Lerato abandoned the process and moved out of the house, taking her belongings."
