Nicki Minaj's wardrobe is a trippy mind warp of rainbows and geometric forms.

The 28-year-old queen of rap flaunts a kaleidoscope of colors and shapes in each and every outfit she wears.

When she steps out, all eyes are on her.

From rainbow-colored hair and tutus to skin tight jumpsuits and candy jewelry, Minaj keeps the world guessing.

She appears on the cover of the latest issue of fashion bible W Magazine. Photographer Francesco Vezzoli transformed the typically Harajuku Barbie-styled singer into various regal woman from throughout history.

In her performances, Minaj makes very explicit and ­challenging use of her beauty and her body, so I thought of comparing her to some of the most famous courtesans in history: the Marquise de ­Montespan, Comtesse du Barry, Madame de Pompadour, and ­Madame Rimsky-­Korsakov, said Vezzoli who shot the editorial spread.

Whether Electrified Barbie or Royal Princess, the Trinidad-born rapper is a fashion icon.

Some of her favorite pieces?

I tend to like booties...and really flashy shoes: totally studded out, in five colors with an insane platform, she told Elle magazine.

After the success of her Pink Friday lipstick for MAC, Minaj has teamed up with OPI nail polish to launch a collection of six polishes due out in January 2012. The paints will be $8.50 each and will carry the names of some of Minaj's biggest hits like Pink Friday and Save Me.

But this girl is not only about make-up and stilettos.

She knows how to make it with the big boys.

I always wanted to play with the boys, she said to Elle. I didn't want to be a pawn in their game or have a sidekick role. I wanted to be more of a lead character -- a superhero.

Minaj has certainly proved she is here to stay. She even dubs herself the Female Weezy.

In September 2010, Minaj performed Monster with Kanye West and Jay-Z at Yankee Stadium. The crowd went wild for the petite, pink-haired rapper. And she had not even released an album of her own yet.

Then Pink Friday came out and the world saw that Nicki Minaj is no second fiddle act.

Oh, no. Nicki Minaj is meant for center stage.
