Another writer, NIcholas Liddle, said "Kim and Kanye's family is cute as f. but Psalm West?".
The new child joins North, 5, Saint, 3, and one-year-old Chicago.
She revealed that the newborn looks just like his sister Chicago.
There had been plenty of interest about what the baby boy's name but the couple have a history of waiting a few days before revealing their children's names.
The baby is their second boy and the second to be born via surrogate because of a potentially life-threatening medical condition that complicated Kardashian West's two pregnancies.
"I love my surrogate, we have a really good relationship".
She explained that it had meant to be Kim who would appear on the show - however, their surrogate had gone into labour.
Yet she was left bereft when doctors told her that there are too many risks if she gets pregnant and that it would be life-threatening. But I really was feeling that, and my brother approved that.
Thoughts on the little one's name, Perezcious readers??
