The 30-year-old singer even discussed the issue with her family and mentors before signing the deal with 'American Idol' bosses, the Hollywood Reporter said.
"(Before joining) I had a lot of talks with people - my family, my best friends, my label, (mentor) Lil Wayne, management and then the producers," Minaj said.
"(There is) a judgemental culture in hip-hop. Sometimes you are afraid of being too famous because it is almost, like, is that even cool? Being that accessible, someone you see on TV every week? I never pictured myself as that type of person. I am still surprised that I decided to do it," she added.
Minaj will be seen alongside singer Mariah Carey, Keith Urban and Randy Jackson when season 12 kicks off in US from January 16.
