The "KUWTK" star has been open about wanting to have a second child and trying hard to make that happen. Kim has even incorporated the attempt on her show.
"We are trying," Kim told E! News last month about wanting to conceive again. "We try every single day. You can't try harder than we try."
The couple hasn't revealed the due date, although TMZ reports that it's December, but we're sure the birth of North's little brother or sister will be on par with the Royal Baby frenzy from last month.
