Better after babies!

Kim Zolciak is a mother-of-six, but she looked better than most 20-year-olds in these bikini snapshots she posted during a day of swimming with her children.

"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 captioned one of the Instagram photos.

In another, the reality star poses in a different swimsuit and reveals that her body has always looked this good! "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 explained to her followers.

We have to wonder if she got a tummy tuck after her last pregnancy, though, because her abs look too good to be true!
