Khloe Kardashian has a new addition to her fam … her surrogate has given birth to a baby boy!

A rep for Khloe confirmed the news to Page 6.

TMZ broke the story … Khloe and Tristan Thompson were having another child together via surrogate.

The timeline of the pregnancy seemingly indicated they made the decision prior to their most recent breakup.
