Don't be tardy for the pool party!

Kim Zolciak welcomed her fourth child, son Kash Kade, just six months ago, and already the blonde bombshell is back in fighting form!

The Real Housewives of Atlanta star donned a red swimsuit that showed off her incredible post-baby body in this Instagram snapshot Wednesday, and she insists that shedding pregnancy pounds isn't all it's cracked up to be!

"I gained probably 35 pounds and I just lost it all in two weeks. I just don't stress about it! It just kind of falls off, I guess. It's weird. I don't work out at all. And I eat very bad! I do think breastfeeding definitely helps. But I am lucky," she told Us Weekly following the birth late last year.

So is the reality star finished expanding her brood, or will there be more little ones in the future?

"I just love being a mom. That's what it's about. When I'm 65-years-old, I just want to have grandkids and kids around me! So, I don't know, we might try for a little girl, but we'll see what happens. But this hoo ha needs to heal, honey! Two babies 14 months apart is a lot!" she explained of her further pregnancy plans.

This Southern stunner just wrapped filming the second season of her Bravo spinoff, so maybe a new baby plot line will guarantee season three?
