Kylie Kicks Off Birthday Bash With Caitlyn, Kris & Her Sister Squad

Oh, to be 18 again.

Kylie Jenner might not officially be 18 just yet (her birthday is August 10), but in true Kardashian-Jenner style, she's already started celebrating.

Turning the big one-eight is a pretty big milestone for anyone, so naturally, the over-the-pop celeb family is turning the youngest Jenner's birthday into a multi-day affair.

On Friday, Kylie kicked off the shenanigans in a surprisingly quiet and thoughtful way: Stopping by the Children's Hospital of L.A. to pass out gifts. She then spent the rest of the evening doing, what else, snapping endless selfies with her famous family.

Of course Kim, Khloe, Kourtney and Kendall were all present at the bash, but it's the photo of Kris and Caitlyn Jenner that we really love. Both women look absolutely gorgeous, and it's wonderful to see them getting along.

We're sure this is just the beginning of Kylie's birthday celebrating, and can't wait to see what else those crazy Kardashians have in store.
