Buhari's new wife info

I think there may be some confusion here!

As of my knowledge cutoff, President Muhammadu Buhari of Nigeria is not married to a new wife. He has been married to Aisha Buhari since 1989, and they have five children together.

It's possible that you may be referring to a different public figure or celebrity. If that's the case, could you please provide more context or clarify who you are referring to? I'd be happy to try and help you find the information you're looking for!
