Nicki Minaj worries she always has to be outlandish.

The "Starships" singer is known for her eccentric outfits and outspoken attitude and thinks she now always has to be like that because it will disappoint people if she relaxes.

"So much is taken out of you that you lose yourself. I feel like I've set the bar too high, so I always have to be 'on.' I can identify with Marilyn Monroe in that people saw a beautiful woman, but inside was a fragile little girl," she said.

Nicki also admitted she hopes to replicate the success of hip hop mogul Jay-Z, who is involved in a variety of business ventures, including music, sport, and clubs. Discussing her song "HOV Lane," she said, "That's got so many meanings. It's the HOV Lane, which is the fast lane on the highway and Hov is Jay-Z and it talks about him being a male mogul who's done so much. That's what I want to do. I don't know if the industry is sexist or if it's just that women haven't tried to pursue the goals of being a mogul before. I can only say I'm attempting to become a mogul and doing things I've seen guys in this business do."
