Atiku's new wife
I think there may be some confusion here!
Atiku Abubakar is a Nigerian politician who has been married to his wife, Titi Abubakar, since 1979. They have five children together. There is no public information or credible source suggesting that Atiku has taken a new wife.
It's possible that you may be thinking of another public figure or celebrity who has recently gotten married. If you could provide more context or clarify who you are referring to, I'd be happy to try and help!
