Kim Kardashian forgoes her underwear to slip into daring cut-out dress...

Kim Kardashian posts a bathroom selfie with fiance Kanye West on Friday night

You've got to hand it to Kim Kardashian - the woman is always finding new ways to shock while showcasing her famous figure.

On Friday, that meant going commando and squeezing her curves into a tiny black dress with cut-out panels on the sides from the waist downwards.

The reality star was supporting her fiance Kanye West at his Miami Yeezus concert and the couple had an unusual way of preparing ahead of his performance.

Kim, who is known for her love of selfies, posted a picture of herself and her fiance posing in a rather insalubrious looking bathroom with the caption, 'Bathroom selfie before Yeezus hits the stage'.

In the photo a rather serious looking Kanye stands in the background with his arms by his side whilst the mother of his child pouts while snapping the picture on her phone.

The rapper sported a pair of jeans with a brightly coloured design along with a rather patriotic sleeveless top with the stars and stripes and an eagle emblazoned across the front, along with some heavy chains.

Kim shared a picture of herself with friends Pippa Larsen and Loren and Amber Ridinger who all looked very similar with their glossy highlighted tresses

Meanwhile new mother Kim flaunted her post baby body in her tight black dress, that also highlighted her shapely derriere and left her legs on show.

Kim wore her highlighted hair loose ad hanging around her shoulders and kept her jewellery minimal, letting her enormous Lorraine Schwartz engagement ring take centre stage.

The 33-year-old beauty wore a pair of black strappy patent high heels to add some height to her petite 5ft 3in frame.
