We have a name! After welcoming the arrival of child No. 4 surrogate a week ago, Kim Kardashian unveiled the name of hers and Kanye West's new baby boy on Friday (May 17): Psalm West. 

The reality star made the announcement by posting a screenshotted text message — or hymn —  from Yeezy on Mother's Day. "Beautiful Mother's Day. With the arrival of our fourth child, we are blessed beyond measure. We have everything we need," he wrote alongside a photo of baby Psalm in his crib. 

That last line might be familiar to fans of Kanye, as it's from a track that he's repeatedly performed at his Sunday Service shows and rumored to land on the mythical Yandhi album. Psalm joins North, Saint and Chicago as the newest member of the Kardashian-West family.
