Kim Kardashian proudly displayed the string of her underwear as she posed for a sultry set of photograph amid early birthday celebrations.
The Keeping Up With The Kardashians star turns 40-years-old on Tuesday, and it seems the celebrations are well and truly under way with four days to go.
Taking to Instagram on Friday, the mum-of-four posed in a backless black dress designed by Matthew Williams while draping a giant statement handbag over her arm.
The design of the dress included a huge round cut out across the back – with Kim drawing attention to her famous bottom as she wore a bright red G-String that peeped out through the gap in the fabric.
The famous reality star appeared to perform a stripper drop dance move as a photographer snapped, with one image showing her dipped close to the floor while her hair swished around.
While a third snap showed her looking over her shoulder while hair extensions draped down to her infamous derrière, the brunet locks licking the top of her underwear.
Kim also took to Instagram Stories to show off a new dress designed by Alexander Wang and inspired by herself.
The star wore the shimmering crystal infused outfit which featured her own body dressed in a pink bikini.
The photo and video self promotion came hours after the star shared video of herself erupting from a giant birthday cake.
The star had been snapped emerging from the top of a giant cake in an eccentric birthday photoshoot ahead of her birthday next week.
The reality TV star turned fashion and make-up mogul got the party started weeks early as she took part in a special photoshoot to mark her milestone day.
Defying her years, Kim was looking flawless and completely wrinkle-free as she smouldered at the camera.
All while acting as a candle as she popped out of the top of a giant homemade cake.
The 39-year-old even managed to look glam while awkwardly positioning herself to accentuate her ample assets at the camera in a tiny silver bikini.
