West posted an adorable snap to her Instagram page on Monday with the caption, “Psalm Ye.”
It’s unclear if “Ye” is his middle name, which is his father, Kanye West’s nickname.
The couple have not publicly shared the middle names of their other children, Chicago, Saint and North.
The photo comes exactly one month after the Wests welcomed their fourth child via surrogate.
West has been open about her pregnancy struggles, having suffered pre-eclampsia, a complication characterized by high blood pressure with both North and Saint. She also had placenta accreta in both pregnancies, which occurs when the placenta attaches too deeply in the uterine wall.
