Kim Kardashian gave the world its first sneak peek at her newborn son, Saint West, on Instagram Saturday night. The photo of Saint shows just his tiny hand clasped around the finger of his big sister North.

Kardashian captured the precious moment between brother and sister and captioned the photo, "She said, 'He's my best friend.'"

Aww!

Saint was born on Dec. 5. Kim announced his birth with a photo of her holding hands with husband, Kanye West, as well as their family in emoji characters.

The mother of two has yet to reveal the rest of Saint in any photos. She and Kanye have reportedly received offers between $2 and $2.5 million for the first photos of the baby and the entire family.

The annual Kardashian Christmas card featured only the youngest Kardashian members this year including Kim's daughter North and Kourtney's three children with Scott Disick, 6-year-old son Mason, 3-year-old daughter Penelope and 1-year-old son Reign.

Kanye shared the first photo of North about two months after her birth on June 15, 2013. The big reveal came on his mother-in-law Kris Jenner's now defunct talk show, "Kris."

 She said, "He's my best friend."
