Sometimes we forget reality star Kim Zolciak has a whopping six kids, and if you take a look at the two stunning bikini selfies the Don’t Be Tardy star shared on Instagram on July 29, you probably won’t even believe that this hardworking mama carried and delivered six babies — the latest being 8-month-old twins Kane and Kaia — but indeed she did!

Kimmie is rightfully proud of her bikini body, and she shared the first sexy snap after taking her young sons for a dip in the family’s pool. “Obsessed with @beachbunnyswimwear took my boys swimming today! They missed daddy throwing them up in the air and when I attempted to do it ... Well.. Let's just say they didn't go very far!! #nomakeup #natural,” she wrote in the caption. The black two-piece is doing wonders for Kim, as we can see her toned abs making an appearance.

The former RHoA must have loved how the first bathing suit shot turned out, because she shared another one just an hour later, this time rocking strapless black bikini with neon accents. Even Kim was amazed by how hot she looked in this getup, writing, “Another @beachbunnyswimwear I tried on today!!! Im obsessed with swimsuits! I won't even tell u how many I own!! #beenthesamesizemyentirelife Even after 6 kids!! #grateful #curvalicious.”

Many of the comments on Kim’s photos were overwhelmingly positive — with fans calling her body things like “amazing” and “sick” — but there were still some doubters out there who credit Kim’s killer physique to a little nip and tuck.

To be fair, Kim has discussed getting plastic surgery in the past and even pays a visit to Dr. Leonard Hochstein (husband of Real Housewives of Miami star Lisa Hochstein) on this season of DBT, but she’s been rather coy about whether or not she actually went through with her desired “mommy makeover.” Looks like we’ll have to wait and see!

Do you think Kim’s had plastic surgery recently, or is she just blessed with some really great genes? Vote below!
