Kim Zolciak's twins are nearly here: the expectant mom has revealed she's due to give birth next month.

The Don't Be Tardy... star shared the update on her growing brood in a sentimental Throwback Thursday photo on Instagram. The photo shows Kim and husband Kroy Biermann exchanging phone numbers on the day they met—a moment captured on The Real Housewives of Atlanta.

In the caption, Kim refers to the snapshot as "The moment my life changed forever." Discussing their soon-to-be family of eight, she continues, "We have since welcomed 2 beautiful boys, expecting twins NEXT MONTH and Kroy is legally Brielle and Ariana's father!"

When the couple's meeting played out in front of cameras, it was clear from the beginning there was an attraction—she immediately nicknamed him "tight ass"—but, who could've imagined just three years later the couple would resemble a modern day Brady Bunch. As Kim noted in her post, "Your life can change in a second literally!"
