Kris, 63, was beaming when asked about Psalm at the Fresh Air Fund's Annual Spring Benefit honoring Tommy Hilfiger on Wednesday, May 22.
"The inspiration was the Book of Psalms in the Bible," the momager told ET when asked how Kim, 38, and Kanye, 41, decided on their fourth child's name.
"I think it’s just a wonderful way to celebrate how they feel. And he’s such a blessing, so it's perfect," she added. "He's just adorable!"
Although the KKW founder and rapper share three other children together, North, 5, Saint, 3, and Chicago, 16 months, it is unknown whether or not they will be trying for a fifth baby!
