Kim Kardashian posts extremely raunchy G-string bikini shot

Kim Kardashian has posted one of her raunchiest bikini pics yet as her sister prepares to walk down the aisle in Italy.

Kim Kardashian has shared a very raunchy holiday snap, posing in arguably the world’s tiniest bikini bottoms.

In the throwback picture – which was shared to Instagram – the reality TV star and cosmetics mogul, 41, looked back at the camera as she sauntered toward the water’s edge.

She captioned it simply: “sun bum”.

The image appears to have been taken during her Sports Illustrated photo shoot, which was published earlier this week.

Kim flaunted her incredible figure in a nude bikini from her shapewear brand SKIMS, paired with, bizarrely, a pair of opera gloves in the same material that extended nearly all the way up to her shoulders.

Elsewhere in the shoot, she posed in a number of newly-released Skims styles, including a silver bandeau bikini, metallic wetsuit and black vinyl bikini.

Sharing the cover with her 311 million Instagram followers, Kardashian wrote: “OMG I’m a Sports Illustrated cover girl!!!!”

“We shot this back in January and it’s been so hard to keep this cover a secret!” she added.

“For the location we went back to one of my favourite places in the world, the Dominican Republic!

“It’s such an honour and a dream to be on the cover of Sports Illustrated Swimsuit Edition. Bucket List goals!!!!”

Meanwhile, the entire Kardashian clan is reportedly gathering in Italy this weekend for Kourtney’s lavish wedding to Blink 182 drummer, Travis Barker.

The pair legally tied the knot at a Santa Barbara courthouse last Sunday ahead of the European nuptials.

TMZ reports that Kourtney and Travis have rented historic building Castello Brown, which overlooks Portofino harbour.

The happy couple were spotted in the coastal town on Friday, holding hands as they took a romantic boat ride before boarding a private superyacht.
