Logan Paul and Nina Agdal don't know their baby's gender just yet, but it's clear the WWE Superstar is hoping for a girl ... gushing over the possibility and saying, "I'm just gonna melt."
The Maverick opened up on his impending fatherhood during his "Impaulsive" podcast this week ... and he couldn't help but get excited over the huge milestone.
Paul explained his life will change forever once they welcome the kid to the world ... 'cause for the first time, he won't be prioritizing himself -- it's all gonna be about his partner and the new family they created together.
