Minaj, who welcomed her son in September, revealed that her water broke after had finished taking a shower and asked her husband to “rub [her] back.”

“As soon as I started scooting over to him in the bed I just felt the water start coming out. I was weirdly calm & I quietly said ‘omg, I’m about to be in labor,’” she recalled.
