‘My twin,’ the 43-year-old reality star — who teased her SKIMS Valentine’s Day collection earlier in the day — captioned the image she shared to her Instagram Stories, although she didn’t specify exactly how old she was in the photo.

Young Kim sported modest studded earrings, unlike her daughter, and her dark hair was styled straight, while Chicago had her curly long locks styled in cute top knots.

Kim Kardashian, 43, called her youngest daughter Chicago, six, her ‘twin’ in a cute side-by-side photo posted to her Insta Stories on Thursday

The photo included a childhood picture of Kim that revealed that she looked even more like Chicago when she was approximately her age

The comparison also highlighted the life of luxury that Chicago has grown up in as the child of one billionaire — Kim — and one former billionaire — her father Kanye West, after he lost hundreds of millions of dollar in business deals due to antisemitic statements.

The younger sister of North West wore a sparkling diamond-encrusted necklace, while Kim’s photo was relatively luxury-free.

The photo of Chicago was taken from the Kardashian–Jenner family’s 2023 Christmas Eve bash, which previously set Kim’s fans and followers buzzing over the shocking lookalikes when she posted the photos.

‘Chicago is literally your mini you!’ one astounded fan commented on her post, while another raved, ‘Chi is your twin, she is beautiful.’

A third user predicted that the Chicago would grow up to become the ‘that girl’ of her generation.

In addition to her mini-me, Kim and her ex Kanye share daughter North, 10; son Saint, eight; and son Psalm, four.

Back in October of 2018, when Chicago was just eight months old, Kim already was certain that her youngest daughter was her spitting image.

After calling Chicago ‘such a doll’ on Ashley Graham’s now-defunct Pretty Big Deal podcast, Kim said Chicago, ‘looks like, honestly, my twin mixed with Saint. It’s like the two of us in her.’

Saint is also commonly compared to his mother, whereas Kim’s oldest daughter North West is often said to more closely resemble her father Kanye.

Kim likely had Chicago’s resemblance to her on the brain in recent days, as she celebrated her daughter’s six birthday just days earlier on January 15.

Kim’s fans previously noted just how similar Chicago looks to her mother when she posted photos of the two together from her 2023 Christmas Eve bash

On her birthday, Kim reposted a Kourtney Kardashian fan account’s post with photos of Chicago still looking just like her mother even as a baby. The resemblance was even stronger in a picture of her in which a topless Kim held a naked Chicago against her chest

Kim filed for divorce from Chicago’s father Kanye in February of 2021, but the divorce wasn’t finalized until November 2022 after they came to an agreement on child support and custody.

The exes were married back in 2014.
