Bbnaija 2019 yet again big brother introduces another new housemate

I think there may be some confusion here!

Big Brother Naija (BBNaija) 2019 has already concluded, and the winner was Mercy Eke. The show ended on October 6, 2019.

It's not possible for Big Brother to introduce a new housemate in 2019, as the show has already wrapped up.

However, if you're referring to a new season of BBNaija, which is often referred to as "Shine Ya Eye", the show premiered on July 24, 2021, and is currently ongoing. If that's the case, I'd be happy to provide updates on the new housemates and their journey in the house!
