The birth comes after Kardashian West disclosed she's studying to be a lawyer through California rules that allow for professional mentorship over law school.

The couple has not yet revealed the name of their baby boy, but fans are sure it will be as different and as quirky like their three kids. Kim is known to wait a few weeks before revealing the name.
