Kylie Jenner's "favourite sister" is totally not who you'd expect

Plus another face swap to haunt your dreams.

Kylie may have spent her weekend dominating Coachella, but she didn't forget her big-sis Kourtney's birthday on Monday.

Wishing her a happy birthday through Instagram, the caption surprised us a lil.

"Lol I love you Kourtney. You already know you are my favorite sister these days... Thank you for teaching me to see the glass half full through everything. Happy birthday 💛 ps. Mom in the background"

While you were probably thinking that Kylie and Kendall were #SisterGoals (they are), she admits Kourt is her fave.

This is just as hard as keepin' up with her hair choices, especially since she recently admitted she would most likely want to be Kim.

Also, A+ for that face swap and Kris Jenner's sneaky photobomb.
