In an event held by Wasafi Fm, Diamond revealed Zari cheated on him.
He claimed that she had cheated on him with Nigerian superstar Peter Okoye from the group P Square.
He claims that he saw text messages between them and even confronted her.
He went on to allege that she had also cheated on him with her gym trainer and even brought him to his house,in their bedroom.
“Namheshimu Zari ni mzazi mwenzangu, alikuwa wife material. Alikuwa anataoka na Peter wa Psquare, niliwahi kukuta sms nikamuuliza."
“Alikuwa anachepuka pia na Trainer wake na alikua anamleta hadi kwangu, lakini sijawahi kufunguka. Na ukweli sijawahi kuachwa na Mwanamke, Ukizingua nitakupiga matukio utaondoka mwenyewe,” narrated Diamond.
But Zari has responded denying all the allegations, labelling him a liar and a serial cheater whose word cannot be believed. She posted on Instagram that the superstar once disowned his own child with Hamisa Mobetto.
