Catch up on Don't Be Tardy on the Bravo App.

Don't Be Tardy star Kim Zolciak is getting ready to give birth to twins. But in the meantime, the Atlanta bombshell knows how to have a good time: a trip to Walmart!

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.
