North West’s baby brother has a name. Kanye West and Kim Kardashian have announced the newest addition to their family: Saint West.

In a post on her website, Kim wrote, “To our fans. Saint West. 12.05.15. 8 pounds, 1 ounce.” She also posted an Instagram with emojis representing each member of the family—Kanye, Kim, North, and Saint—with an additional caption confirming his name.

The newborn does not have a middle name, despite reports that the couple would use Robert, in honor of Kim’s late father Robert Kardashian.

Saint joins his big sister Nori, who turned two in June.

Congrats to the happy family!
