Braless Nicki Minaj shows under-boob

Most fans know to expect the unexpected when it comes to Nicki Minaj's wardrobe.

But that knowledge clearly wasn't enough to prepare onlookers for the outfit the 31-year-old stepped out in on Friday night.

The US rapper was sporting one of her most revealing ensembles yet as she partied away at the uber cool Club 79 in Paris after performing on stage with Beyonce.

Nicki was seen dancing in the VIP area wearing a teeny turtle neck crop top, which looked a few sizes too small for her ample cleavage.

The fact that she wasn't wearing a bra meant that those close by were given a good glimpse of some serious under-boob as her top rose up while she danced.

She completed her outfit with a pair of matching skin-tight leggings, which showcased her famously curvy derriere, and a pair of black and gold ankle boots.
