Khloé Kardashian Posted The Most Hilarious Birthday Video For Kylie Jenner

The Kardashian/Jenner family is having a hard time coming to terms with the fact baby Kylie is already 19 years old, which is a little confusing for the rest of us, who thought she was at least 32.

Already a business owner, massive social media star and longtime reality TV regular, Kylie Jenner has only been on this earth 19 years, somehow.

Regardless of whether she's 4 or 400 years old, IT'S KYLIE'S BIRTHDAY, PEASANTS!!!

Marvel at her influence. Celebrate her beauty. Google her net worth.

Khloé Kardashian posted a silly clip on Instagram of herself and Kylie in honor of her little sister's August 10 birthday.

Momma Kris posted a collage of throwback photos to honor her youngest, hashtagging “proud mama” in true Kris fashion.

The truth is, Kylie grew up a long time ago. There's no need for family members to get so sentimental over the passing of time.

It's not like turning 19 is going to cause Kylie to suddenly — OMG KYLIE WHAT DID YOU DO???

Wow, turning 19 has changed Kylie Jenner.

The Kylie Jenner we've known all these years is gone... forever.
