The "Super Bass" hitmaker, who is known for her colourful personality, says her accent created a lot of problem during her younger days, Elle magazine reported.
"I went through a lot of bullying early on. Girls made my life a living hell. We had come to America from a different country (Trinidad). My brother and I had accents. It was very tough.
"So I've always put up this wall - it was a self-defense mechanism growing up - because I was almost expecting people to attack me. And I still have it. It's sad."
"I'm thinking of a legacy that I can be proud of and wealth that my grandchildren can use to go to college. So world domination - in terms of providing for my family - is absolutely my goal.
