Kim Kardashian turned up her megastar magnetism to full advantage in a set of sizzling new snaps she posted to Instagram on Tuesday.

The 42-year-old reality TV bombshell fired up her social media to plug her shapewear line SKIMS – and show off her enviable figure in the process.

She decked herself out in a clinging midnight blue set of workout gear that emphasized her ample cleavage and vertiginous legs.

Her outfit also bared her sculpted midriff, over a year after she rapidly lost 16lbs to fit into Marilyn Monroe’s ‘Happy Birthday Mr. President’ dress to the Met Gala.

Tuesday’s Instagram broadside came against the backdrop of Kim’s seething feud with her sister Kourtney, which has been unfolding on The Kardashians.

Earlier this week, Kourtney continued to shut down Kim’s allegation that her friends are participating in an anti-Kourtney group chat.

The TV personality, 44, and the SKIMS founder engaged in a vicious war of words in the season four premiere of The Kardashians as their feud boiled over.

During the heated phone conversation, Kim claimed that Kourtney’s close friends had joined her ‘Not Kourtney’ WhatsApp chat to discuss her.

Their row began last season when Kim collaborated with Dolce & Gabbana on a nineties themed collection, which Kourtney insisted was copying her wedding theme, which she hosted in Postitano, Italy, months earlier.

Kourtney has since taken to Instagram to prove that her friends are not involved, by sharing a screenshot of friends Allie Rizzo Sartiano and Simon Huck saying ‘trolls’ are attacking them for Kim’s claims.

Kourtney later confirmed who was in the chat by responding to a fan’s comment under a post of her baby shower.

‘Are those friends on the ‘not Kourtney group chat’ Cause if so we don’t need them there,’ one fan wrote, to which the Poosh founder responded: ‘No the members of that chat are namely Kim, Khloe, Kendall and Kylie. Case closed.’

To show that her friends had no part in the chat, she shared a screenshot of a text message conversation between her close pals Simon Huck and also Allie Rizzo Sartiano onto her Instagram stories on Friday.

Allie had penned, ‘Should I soft launch the YASS Kourtney group chat?’ with Simon responding with, ‘OMG please! These trolls keep DM’ing me accusing me of being on the other chat.’

Sartiano typed, ‘I’m like if only they knew our anxiety about meaningless endless chit chat. I mean over a martini we will debrief but but dang for a group char that didn’t exist I am fidgeting.’

Simon then wrote, ‘Kim threw us all under the bus when there was not one actual friend on the chat.’

The hullabaloo began when Kim confronted her older sister on the phone regarding concerns over changes in her personality since Kourtney’s May 2022 marriage to rocker Travis Barker.

‘You’re a different person. We all talk about it,’ the Skims founder revealed, referring to the group that included sisters Khloe, 39, Kendall, 27 and Kylie, 26. ‘We’re all confused, and we’re on a group chat that’s actually labeled “Not Kourtney.”‘

Kim also claimed Kourtney’s kids, Mason, 13, Penelope, 11, and Reign, eight, had also all ‘come to [her] with problems they have’ about their mom.

The interaction ended with a tearful Kourtney calling Kim an ‘egotistical narcissist’ and telling her, ‘You’re just a witch and I hate you.’ Many of Kourtney’s fans seem to agree with the sisters’ assessment.

The problem isn’t Kim,’ commented one plainspoken follower.

‘The problem is you don’t know who you are. You’re lost. You’ve lost yourself in your husband and you can’t help that you don’t know who tf you are so you attack the one person who is so strong in herself.’

They ended the message with a cruel, ‘you’re pathetic.’

‘That one girl who turns into whoever she dates…’ observed another. ‘Why did she take Travis’ whole personality? Lmao copy and paste,’ wrote a third.

Many have jumped to the expectant mother’s defence.

‘Sorry Kourtney for your sisters and friends being so mean to you. You don’t deserve that. Cut them off and be happy ❤️ that’s not real family, ‘advised one observer.

‘You look beautiful in your pregnancy, commented one consoling fan next to a post promoting Kourtney’s Boohoo collaboration.

‘It is sad to read about the issues you are having with Kim. Just be true to yourself as you cannot choose your family but you can choose your friends.’
