Kim Kardashian West and Kanye are getting ready to welcome their fourth child and the second boy as their surrogate is in Labor.

Our sources say mom and dad were at the hospital Thursday night with the surrogate. Don’t know for sure if they’ll be in the delivery room, but she was the last time around for the birth of Chicago. 

As we reported … KW and KK hired a new surrogate to carry their fourth kid to term — not because they were dissatisfied with the last one … she was simply unavailable. The woman — who was in her early 20s — had her own child this past December … less than 12 months after popping out baby Chicago. As a result … the couple had to go with another surrogate.

This new surrogate’s profile never became clear … but ya gotta imagine mom and dad went with someone who was equally capable. 

Kim and Kanye used a leftover embryo they created to bring this newest baby to life. He’ll join three siblings — North, Saint, and Chi — as the sixth member of the family.

As of now, there is no word yet on if she has given birth, but as soon as we get the details we will keep you updated!
