Another little West is on its way!

Kim and Kanye's surrogate is three months pregnant with their third child, Us Weekly reports.

The woman, who is a San Diego mom in her late 20s, is due to give birth around January 2018. The couple selected her to carry their baby after doctors told the reality star that another pregnancy would be too dangerous for her health, due to the condition placenta accreta.

The pair are paying the woman $45K in monthly installments, and have already paid the surrogacy agency $68,850 as a deposit. Among their requests? No drinking, smoking, or drug use, no raw fish, and no handling cat litter. Pretty standard if you ask us!

Kimmy K toyed with the idea of having Kourtney or Khloe carry a baby for her, but ultimately settled on a professional to do the job.

North and Saint better make room for the newest addition!
