Confirming the news, Kim has shared a note welcoming the latest addition to their family, all while thanking the surrogate, doctors, and nurses.
It had previously been reported that Kanye and Kim decided to use a surrogate due to Kim's placenta accreta, "a serious pregnancy condition that occurs when blood vessels and other parts of the placenta grow too deeply into the uterine wall."
The Wests' new child will be the younger sister to North and Saint.
