Kim displayed her shrinking arms and waist in a skimpy black bra and matching panties.

The mother of four posed with her hand in her hair as she pouted at the camera in the middle of her dressing room.

She captioned the snap, “IDD8ME,” which translates to: “I’d date me.”

While many of her fans praised the shot, some pointed out that Khloe had shared a similar thirst trap just hours earlier.

The Good American founder posted a video of herself posing sultrily in her closet while wearing a cut-out dress.

The 39-year-old pouted as her makeup artist and hairstylist worked around her.

One fan commented on Kim’s version, “Had to one up Khloe’s post huh….” and another added: “Always one-upping the sisters lol.”

One even suggested the move would make part of a sibling rivalry storyline on the next season of their reality show, The Kardashians.

“Don’t spoil the next season storyline!!” they joked.

Both Kim and Khloe have sparked concern with their drastic weight loss in the past year.

An insider exclusively told The U.S. Sun in late 2022 that Kim’s friends and family are worried that the star has pushed herself too far.

“Kim looks amazing, always, but she’s good at keeping how stressed she is hidden,” the source said.

“She’s the skinniest she’s ever been and barely sleeping. Her family knows that a lot of this is her rebounding from a very controlling marriage, and her determination to show Kanye [West] how much better she is doing without him.

“But whereas before she was incredibly healthy and well-rested, now she’s constantly jetlagged and she’s finding it hard to fit workouts in. I think Kim’s really struggling but won’t admit it.”

The source added Kim “loves how skinny she is” and plans to drop two more pounds so she can be under her goal weight.

In June 2022, the Skkn founder revealed she had lost 21 pounds.

She made the confession after admitting to losing 16 pounds in three weeks to fit into the iconic Marilyn Monroe dress she wore to the Met Gala in May.
