Zolciak posted a photo of her ever-increasing belly on Instagram, along with her plans for the day.
"Wiggin' it to Walmart this morning!" she wrote. "This belly is so heavy! Not too much longer! #twins #thankgodforSweats."
It's been a busy few weeks for Zolciak: her husband Kroy Biermann recently tore his Achilles tendon, forcing him to sit out the rest of the football season.
But Kim, who's been quite proud to show off her ever-increasing bump online, sure knows how to keep a smile on her face.
Really looking forward to your show. I have enjoyed watching you from the first days of your stint on Bravo, going through some wild & crazy times, to your now being such a good wife & Mother. Thanks,Kim,for sharing your life & lives of your family with us. You were always my favorite on Housewives of Atlanta and I'm thrilled you have your own show. I wouldn't miss it. Good luck & prayers for all of you & special prayers for Kory to heal.
