Real Housewives of Atlanta star Kim Zolciak gave birth to her fourth child, son Kash Kade, on August 15, and a mere two weeks later the reality star is showing off a seriously svelte physique!

Her teenage daughter Brielle snapped this pic of her mom in a tight black tank and sweats and captioned the photo, "Seriously... who looks like this after 2 weeks of having a baby?" We totally agree!

The wig-loving diva has had quite the whirlwind year! Not only did she welcome a new baby, the 34-year-old also had cameras following her everywhere as she filmed her spinoff and planned her extravagant nuptials to now-husband Kroy Biermann.

One thing's for sure - Kim isn't tardy for her gym sessions!
