Even Kylie Jenner Thinks She's Growing Up Too Fast

Kylie Jenner's grown up before our eyes, and it all just happened so fast. Even she knows it.

The "Keeping Up with the Kardashians" star, who turns 18 next month, shared a throwback pic on Instagram Tuesday poking fun at that very fact. In the photo, we see a screen grab of a younger Kylie from an old episode of "KUWTK," with "I promise that I won't grow up too fast" captioned across the bottom.

So much for that promise.

The youngest member of the Kardashian-Jenner fam captioned the pic, "Dammit, Kylie!" and added a laughing-so-hard-it's-crying emoji. So, there you have it: Kylie is more than aware she's grown up quickly. And come August 10, she can legally call herself an adult.

So there.
