Celebrity power couple Kanye West and Kim Kardashian West have revealed the name of their fourth child.

Psalm West was born on May 11, and his name was revealed on Saturday (NZ time) in an Instagram post by his mother.

"Beautiful Mother's Day," a caption read below a dimly-lit photograph of the baby lying in a basket. "With the arrival of our fourth child we are blessed beyond measure."

The post concluded, "We have everything we need."

The Wests might have four kids, but with an estimated fortune of US$500 million between them, they probably do indeed have everything they need.

Their other three kids also have unique names - North, Saint and Chicago. Both Psalm and Chicago were carried by surrogates, after their mother had complications with the first two.
