Mmusi maimane celebrates 17 years of marriage with wife
I'm not aware of any information about Mmusi Maimane celebrating 17 years of marriage with his wife. Mmusi Maimane is a South African politician who served as the leader of the Democratic Alliance (DA) from 2015 to 2019. He is married to Natalie Maimane, and they have three children together. However, I couldn't find any information about them celebrating 17 years of marriage.
It's possible that you may be thinking of a different person or couple. If you could provide more context or clarify who Mmusi Maimane is referring to, I may be able to help you better.
