The power couple on Thursday welcomed the baby through surrogate, and joins sisters North, 5, and Chicago 1, and brother Saint, 3.

When Kourtney Kardashian appeared on "The Ellen Show" the same day, she revealed that Kim was supposed to join her but was unable to since the surrogate was in labor.

In January, Kardashian West said she had been Googling Armenian boys' names in honor of her family's heritage but hadn't found anything.
