Kim Zolciak’s twins had their first photo shoot in their mom's tummy!

The pregnant Real Housewives of Atlanta star took to Instagram and showed of her growing baby bump.

“Going swimming with the kiddos! The pool makes me feel so much lighter! This belly #twins #excited #blessed #nofilter,” she wrote.

In the selfie shot, the hot mama poses in a hallway, wearing a strapless lace bikini that accentuates her stomach.

Life & Style first reported she was in her fifth pregnancy in June. Kim and her NFL player hubby Kroy Biermann are already proud parents to sons KJ, 2, and Kash, 1. She’s also mom to two daughters from previous relationships, Brielle, 16, and Ariana, 12.

“I’m having twins and I couldn’t be more excited,” shares Kim, who married Kroy in November 2011. “I was completely shocked. I had no idea. It was a natural conception but twins do run in my family so I guess I shouldn’t have been surprised. I can’t believe I am going to be a mom to six children. It’s going to be very busy but it’s a dream come true.”

A friend tells Life & Style that Kim and Kroy were “delighted to discover that they’re going to have twins.”

This much is certain: the blonde reality star loves being a mama.

“I love [motherhood],” she’s told Life & Style. “There’s nothing else in the world like it. I’m just at peace. I was never out there searching for something, but there was always kind of a missing piece, and I have it all now. I literally have everything.”
