Kim Zolciak’s nearing the finish line of her fifth (and supposedly final) pregnancy, this time with twins! Fans and former cast members have marveled at Kim’s ability to get pregnant, seemingly at the drop of the hat (by this Christmas she’ll have had four kids in two years).

But did Kim get a little help with this pregnancy? As it turns out, Kroy and Kim conceived au naturel!

“Conceived naturally @BeUTfyD1s twins run heavy on my mothers side! It comes from the moms side but even my grandpa was a twin!” she revealed.

Though she’s found a younger man in 28-year-old Kroy Biermann, Kim’s only 34 and has plenty of fertile years left! But the wigged-out mama has said multiple times that this will be her final pregnancy.

After the twins are born around Christmas time, Kim will have had six children total! That’s a lot of Atlanta Falcons jerseys to purchase!
