He is a wellness coach, a model and Zari Hassan’s gym instructor. He is popularly known in Tanzania by the single name Tumise. He is the very guy Diamond Platinumz was referring to when he said on Tuesday that Zari cheated on him with P-Square’s Peter Okoye and her personal trainer/gym instructor.

To go back into his story with Zari Hassan, the socialite businesswoman hired Tumise after she gave berth to her second child with Diamond, to help her get back into shape. Zari and Tumise hit gym like crazy and a few moments later Zari was back to shape –with nothing to give away the fact that the bomshell is a mother of five.

But then, even before she split with Diamond, rumours began that because she was spending so much time with Zari to get her hot and toned physique back, the relationship between client and trainer went personal. The gym instructor was involved with Zari’s life to as far as dictating what she ate and drank.

Some even reckoned that Zari had hired Tumise with more plans than just getting help to get back into shape –otherwise (they reckon) why else would she shop a round for such an attractive guy for a gym instructor?
It also began to be rumoured that Diamond quickly grew insecure, wishing his wife had looked around for an ordinary-looking and not a very unattractive gym instructor.
