Buhari new wife wedding

I think there may be some confusion here.

As far as I know, President Muhammadu Buhari of Nigeria is not married to a new wife. He has been married to his wife, Aisha Buhari, since 1989. They have five children together.

It's possible that you may be referring to a different person or a false news report. If you could provide more context or clarify what you're referring to, I'd be happy to help you further.
