With a body like that, it's hard to believe Kim Zolciak gave birth to twins just eight months ago!

The former Real Housewives of Atlanta star, 36, is apparently genetically blessed, though. On Tuesday, she flaunted her flawless figure in two bikini selfies, claiming that "Even after 6 kids," she's been the same size her entire life ("#beenthesamesizemyentirelife")!

Lucky gal, huh? The Don't Be Tardy... star is mom to twins Kaia and Kane, 8 months, Kroy Jr., 3, Kash, 23 months, Ariana, 13, and Brielle, 17. (That's four kids under 4 and two teenage daughters, in case you weren't doing the math!) Kim made sure to note on Instagram that she's #grateful for her #curvalicious post-baby bikini bod. 

That's not to say, though, she didn't gain any weight during her five pregnancies! Kim told E! News last month she gained 50 pounds while carrying son Kash and again with the twins. So how did she shed those pregnancy weight?! "I definitely think genetics play a role, that's No. 1," she admitted. "No. 2, I think with twins that every little morsel of food that you eat...goes to the baby. I made two human beings at the same time and I gained 50 pounds. Which I gained 50 pounds with KJ, so the twins, I think they took it from me."

"And," Kim admitted, "I do wear kind of like a homemade-type girdle after I had the babies, for six weeks, and I'm wrapped so damn tight for a period of time—and it makes your stomach flat as a board."

Noted! The Bravolebrity also credits her diet, exercise and use of Xenadrine for helping to make those pounds melt away. For more on Kim's adventures with hubby Kroy Biermann, her six kids and her post-baby bod endeavors, tune in to Don't Be Tardy... Thursdays at 9 p.m. on Bravo.
