Nicki Minaj causes jaws to drop in seriously racy cleavage-baring and sheer costumes as she brings her world tour to Birmingham

Nicki Minaj certainly pulled out all the stops when her world tour stopped off in Birmingham on Friday night.

The Bang Bang singer caused jaws to drop when she took to the stage in the Barclaycard Arena sporting a number of seriously revealing outfits.

As she strutted out with a baby pink jewel embellished microphone in hand, the star proudly showed off every inch of her hourglass curves.

 Nicki kick-started the Birmingham stint of her Pink Print tour by waltzing out in a shimmering pair of high waist trousers.

Showing off her ample cleavage to the audience, the star simply teamed the bottoms with a sequin bra.

Later in the show, the rapper had a quick costume change, slipping into an almost identical ensemble but this time, it was red in colour.

Clearly though, the attire wasn't quite racy enough for Nicki who then decided to slip into an even more revealing number.

The next time she appeared out on stage, the rapper was wearing just underwear.

Nicki emerged in a bra featuring gold glitter with a matching pair of sequin embellished knickers featuring a gold fringe.

She completed the outfit with a pair of sexy over-the-knee gold metallic boots.

The costume didn't look particularly comfortable but she didn't seem to mind as she waltzed across the stage with her dancers, even stopping to offer one gentleman a lap-dance as she twerked her famous derriere against him.

Nicki has been making her way across the world on her Pink Print tour and the tour has been full of surprises as Nicki was almost given the chance to become British royalty.

Princess Diana's nephew Louis Spencer got to met at her London concert on Saturday and the 32-year-old beauty revealed the late royal's relative had jokingly asked her to marry him after they chatted backstage.

Nicki shared a cheeky snap of her posing alongside Viscount Althorp, who is the eldest son of Charles Spencer, Diana's brother.
