The 18-year-old is killing the game as teenage witch Sabrina Spellman in the Netflix series Chilling Adventures of Sabrina and a quick scroll of her Instagram shows that she has lots of friends.
One of those friends happens to be our fave boy, Timothée Chalamet.
And, Kiernan is most definitely one of his biggest fangirls – she comments on a lot of his Instagram posts.
When we first noticed this, we thought there could possibly be some ~romantic~ vibes between the two, which we totally ship tbh – but as we now know, Timothée is currently dating Lily Rose Depp.
But we were surprised to discover that these cuties actually starred together in the 2015 thriller fantasy movie One & Two, where they played brother and sister.
So it makes sense that the pair are tight and explains why Kiernan is the cutest human/biggest fangirl when she comments on his social media.
For example, Timothée’s latest Instagram post is of a red tree, which he captioned “your tree…” So Kiernan commented “FOR ME???? THANK U!!!!!”
On another tree-related post a few days ago, she also left a cheeky comment of “#art #cool #trees”.
And, our favourite by far is her comment on Timothée’s Instagram post from September 12 (which was his first in a whopping three months!).
“UM HII I MISS YOU,” she wrote.
We ship this friendship with all of our hearts.
