Kim, Kylie And Khloé Wish Caitlyn Jenner A Happy Birthday On Instagram

Earlier today, the many members of the Kardashian/Jenner family took to their respective social media accounts to wish Caitlyn Jenner, who turns 66 today, a happy birthday.

Birthdays are always important, but today is extra special: This milestone b-day marks Jenner’s first as Caitlyn.

Kim Kardashian wished the beautiful Jenner a happy birthday in a playful Instagram post, joking that she wasn’t sure if Caitlyn was turning 1, or 66.

Kylie followed suit, wishing Caitlyn a happy 66th on Instagram and on her app, where she uploaded a short interview video she’d made with the transgender icon.

Khloé, meanwhile, tweeted a pic of Caitlyn from the ESPY Awards and wished her a "happy first birthday."

Happy first birthday Caitlyn!!! — Khloé (@khloekardashian) October 28, 2015

Nothing yet from the other Kardashians (or Jenners), but we’re sure they’ll send Caitlyn some love before the day ends.

We hope Caitlyn has the wonderful birthday she deserves (even if she doesn’t look anywhere near 66).

Happy B-day, Caitlyn!
