Nicki dreams big

The 29-year-old singer recently tweeted she's "working on two books...". She also admitted that she has a desire to expand her career beyond her singing and wants to make it big in the industry like hip-hop star Jay-Z.

"I never thought about music as just being the end-all, be all. I always looked at it like a business, something that I could create an empire out of, So that's why I'm only about to put out my second album and I'm already thinking about this," femalefirst.co.uk quoted Minaj as saying.
