The Keeping Up With The Kardashians teen is boasting over 50m followers, and practically breaks the internet every day with photos of her über-glam lifestyle.
But there's one person in particular who seems to be keeping a close-eye on Kylie's feed - her pal Bella Hadid.
When Bella posted a series of bikini snaps to her page yesterday, we couldn't help noticing that they bore a teeny bit of a resemblance to pictures Kylie's shared in the past.
Cut-out swimwear? Check. Sexy belfie? Check. Courtyard background? Check.
Then we did some more investigating, and it turns out this isn't the first time this has happened.
In July 2015, Bella shared an image of herself rocking a blonde fringed wig and a plum-coloured lip. Which was exactly the same look Kylie had earlier sported for a LOVE magazine shoot.
Of course, Bella and Kylie are friends, so we're sure they're constantly swapping fashion and beauty tips. And we highly doubt Kylie's bothered about any similarities.
But it's still totally uncanny. Check out the evidence...
1) Bella's black cut-out bikini
2) Kylie's black cut-out bikini
3) Also, note Kylie's cut-out swimwear + courtyard pose. Look familiar?
4) Bella's racy belfie
5) Kylie's racy belfie
6) Bella's blonde hair and plum lips combo
7) Kylie's blonde hair and plum lips combo
We're confused. Who's who here?!
