When the Zari was dating Diamond Platnumz's who is 29, she would say that their age difference was not more than 10 years.

However, she never revealed he real age besides saying she was still in her 30s. 

Some Tanzanians branded her 'nyanya' which apart from being a Swahili name for tomatoes, it also means a grandmother or an old woman.

On the hand, Tanasha Donna, the Kenyan media girl currently dating the Kanyanga hitmaker is just 23. She will be turning 24 on July 7. Tanasha was born on July 7, 1995.

She was recently forced to share her age and real identity after some people alleged she was faking it. 

“For all the fools who seem to know my life story better than me and who claim I fake my names, birthday and age. Don’t like my PP pic as we can all relate but you can see that’s my face,” she captioned her passport.

Tanasha who coincidentally shares a birthday with Diamond's mother will be celebrating their big day in a big function dubbed "The Great Gatsby".
