Rapper Nicki Minaj developed a paranoia about "unlocked doors" when she was a child after witnessing her allegedly abusive father drag her mother from the seat of a car.
The Super Bass hitmaker has always spoken candidly about her tough upbringing and her parents' strained relationship, and she reveals she became obsessed with looking out for her beloved mum's safety whenever she and her dad had a falling out.
Minaj tells Cosmopolitan magazine, "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.
"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."
