Kim showcased her famous hourglass figure in a strappy black dress, covered in sparkles and a lowcut neckline.

While Khloe also showed off her incredible curves in a sheer mesh dress, showing her black bra and underwear underneath.

Kim has previously declared Andrea to be her ‘favourite male singer of all time’ and he performed at her wedding to Kanye West in 2014.

And Khloe and Kim took the opportunity to film a hilarious video with the Italian star, poking fun at Kim’s previous feud with their other sister Kourtney.

They shared a video of Kim mouthing along to a voiceover from her own confessional on an episode of The Kardashians.

While the sisters have since buried the hatchet, the third season of their reality show revolved around Kim and Kourtney, 45, butting heads over Kourtney’s wedding to to drummer Travis Barker.

The fight began after Kourtney accused her sister of ‘taking away the specialness’ off her wedding, after Kim partnered with Dolce & Gabbana shortly after Kourtney’s Italian nuptials, which the fashion brand designed.

She calling Kim ‘greedy’ and ‘intolerable’ in one episode, and accused Kim of stealing the looks from the D&G 90s archives that she curated for her Italian wedding.

They both showcased their hourglass figures in daring black dresses, with Kim opting for a sparkly lowcut number and Khloe wearing a sheer mesh dress, showing her underwear underneath

The viral clip saw her saying in a confessional: ‘I got married in Italy. Am I saying you copied me by getting married in Italy? Who performed at my wedding? Andrea Bocelli. Who performed at Kourtney’s wedding? Andrea Bocelli.

‘You stole my f***ing wedding country and my wedding performer. Andrea Bocelli is my favorite male singer of all time, but I’m copying her dolce vita lifestyle? OK.’

Recreating the moment on Monday, Kim donned oversized sunglasses and glittery head scarf as she mimed the lines, before the camera panned over to show Andrea, with Khloe and Kim giving him a hug.

Andrea previously made light of his name being brought up in the Kim and Kourtney drama last summer, taking to his Instagram to write: ‘Dear @kimkardashian and @kourtneykardash, I’m so flattered that you both love my voice and I’ll always be happy to sing to you.’

He then took the opportunity to praise the talent of his son Matteo, adding: ‘Know that there’s a younger and far more helpful artist @matteobocelli who your mother @krisjenner also knows very well,’ with a winking emoji.

His show continued on Wednesday night, and saw him joined by an impressive group of A-list stars once again.
