Auntie Koko is head over heels!

Khloe Kardashian was one of the first people to meet sister Kim's newborn baby boy Saint West, and the proud reality star can't help but gush about the newest addition to the K clan.

"My little nephew was born. He is so cute and so perfect. I love him and mommy and daddy are doing fantastic," she said during a live stream with her fans.

The little guy's name was announced yesterday, but apparently Kimmy K and Yeezy have been calling him Saint for months now, because they believe he was a miracle baby due to the brunette bombshell's fertility and pregnancy struggles.

Khlo seems like the most maternal of all the sisters, so we can't wait for her to have a brood of her own!
