She told the Hollywood Reporter: "I had a lot of talks with people - my family, my best friends, my label, Lil Wayne, management and then the producers.

"Sometimes you are afraid of being too famous because it's 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'm still surprised that I decided to do it."

However, she was persuaded to join the panel - which also includes Mariah Carey, Keith Urban and Randy Jackson - after speaking to Mike Darnell, Fox network's president of alternative entertainment.

Despite a public bust-up with Mariah during auditions, Nicki insists there are no issues with the panel.

She said: "Sometimes things get heated for their own reasons. I don't think the panel has an issue."
