Inspired by a crazy story about Nicki Minaj's alter-ego called Roman Zolanski (she apparently has 7 alter-egos). Some people claim this "Roman" is actually a real demon living inside her. This is what she said about this alter-ego in a interview:
Roman is a crazy boy who lives in me, and he say the things that I don't want to say. He was born just a few months ago, I think he was born out of rage, he was conceived in rage. He bashes everyone and threatens to beat people. He's violent.
Nicki Minaj has a song called "Roman's Revenge". In another interview, she said something very interesting about her song and Roman:
Roman's Revenge is just about taking control, saying Roman is here to stay and anybody that have a doubt in Roman is going down in a coffin.
You can find both interviews here:
