She said the "TV mogul" was pleading with the woman not to leak a video of her husband in a compromising position.
Two weeks after the furore, Kumalo opened a case and went public for the first time about the incident, which she said put a strain on her family.
Kumalo - who owns Top Billing's production house Tswelopele and has shares in Connect TV, which produces top shows such as Our Perfect Wedding, Date My Family and Utatakho, referred all queries to her legal consultant Emma Sadleir.
Sadleir said cases of crimen injuria and defamation were opened at the Midrand police station. She also said the couple obtained a protection order against Phamotse at the Randburg Magistrate's Court.
The legal eagle also cited another case in which two public figures were involved in a
cat-fight that led to the successful prosecution of one.
"In the [TV star] Uyanda Mbuli case, which was also a criminal charge of crimen injuria, [socialite] Joyce Molamu was sentenced to a R6000 fine."
Phamotse declined to comment further this week.
