Kim Kardashian’s youngest daughter, Chicago West, rang in a milestone birthday in true Kardashian child fashion: with a big, over-the-top Hello Kitty-themed birthday party, a sweet Instagram post from her mom and an adorable pair of matching mommy-and-me hairstyles.

Kardashian shared a handful of candid pics of herself and her daughter to mark the momentous occasion, writing, “My twin. Happy 5th Birthday. I really can’t believe you’re 5! I’m so so proud to be your mom, it’s the best feeling in the entire world. You are the cuddliest sweetest silliest most independent caring girl in the whole world and I just love you so much!” In the photos, Kardashian and West cuddle and pose in Kim’s bed wearing matching black sweatsuits and twin hairstyles to boot. Kardashian’s platinum blonde hair is parted in the middle and pulled up into a low knot with a few pieces pulled out for a casual, effortless vibe, while West wears her hair in a similar style, though she’s also rocking mini space buns and braids instead of face-framing tendrils.

The resemblance between the two is uncanny; West has often been called her mom’s doppelganger, and even auntie Khloé Kardashian popped up in the comments to confirm it.
