London: Rapper Nicki Minaj had developed paranoia about unlocked doors when she was a child.

The "Super Bass" hitmaker has always spoken candidly about her tough upbringing and her parents` strained relationship.

She revealed she became obsessed with looking out for her beloved mum`s safety whenever she and her dad had a falling out, contactmusic.com reported.

"My mother left him many different times and came back. He would beg, cry, stalk us... One time, he pulled my mother out of a car and dragged her for two blocks," Minaj said.

"After that I had a phobia about unlocked doors. Anywhere my mother and I were, I made sure the door was locked, because that was my only way to protect her," she added.
