Kim Zolciak Shows Off Flat Stomach in Incredible Bikini Selfies


Kim Zolciak's amazing bikini bod is something you have to see to believe.

Real Housewives of Atlanta star Kim Zolciak has had six kids, but judging from these Instagram pictures she posted Tuesday, getting her bikini bod back has never been a problem for her.

Kim, 36, also went makeup-free in the pics, her hair tied up in a loose bun.

"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.

She followed up the jaw-dropping selfie with another bikini pic in a different two-piece swimsuit, claiming that she's "been the same size her entire life."

"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," she wrote.

Making the photos even more impressive is that Zolciak gave birth to twins Kaia Rose and Kane Ren just eight months ago, in November 2013.
