North & Penelope Love Khloé Kardashian's New Book

Kim Kardashian and Kourtney Kardashian's daughters never fail in being the cutest. On Wednesday, Khloé Kardashian shared a picture of North West and Penelope Disick with her new book, Strong Looks Better Naked. As you can see below, they look really happy to read it. Here's hoping Kim, Kourtney, and Aunt Khloé wait until they're older before letting North and Penelope take a look themselves. Clearly, Khloé was beyond excited to see the two during what I assume is her book tour as she shared alongside the photo,

I love my little ladies!! They were so excited and kept screaming "KoKo!" "KoKo!" North calls me "KoKo Loco."

How adorable is that? If the 31-year-old author wants to sell even more books, maybe she needs to bring North and Penelope on her book tour. I mean, if they're going to be smiling from ear to ear and stopping people in their tracks with their cuteness, that'd probably be a great promotional technique. Obviously, that won't happen, but it's just a suggestion.

Also, it seems like North and Penelope are trying to tell everyone who reads their aunt's book that they will be as happy as they look once they finish.

The cuteness is real, people.
