Kourtney Kardashian Used Instagram To Announce Her New Son's Very Unique Name

The latest member of the family got the royal treatment.

Kourtney Kardashian's mini-brood with Scott Disick has added a bit of a royal flair to its line-up. And by that we mean the name of their latest addition: Reign Aston Disick!

Yes, Reign joins Mason and Penelope to become the most interestingly named trio of Hollywood siblings yet. Though little Reign was born on December 14 — the same day as his older brother Mason, in fact! — it was only on Sunday that the eldest Kardashian made his name known to the world via Instagram.

"Madly in love with my little Reign Aston Disick," reads the accompanying caption to the photo.

Oh, that wee little hand! How cute! The teeny tiniest hand-holding to have ever happened. Reign is the third child for Disick and Kardashian, whose other children are sister Penelope, 2, and big brother Mason, 5.

Congrats to the family on their new addition! What do you think of the name Reign?
