Just last week, the mother-of-six flaunted her svelte bikini bod in a lacy two-piece.
In January, Zolciak responded to speculation that she's been Photoshopping her much talked-about pics on Instagram with a video of herself -- once again -- flaunting her figure in a white bikini. "No need to Photoshop!" she wrote.
ET caught up with the former Real Housewives of Atlanta star last June, when she credited waist trainers for her hourglass figure. And she's even gotten her 19-year-old daughter, Brielle, into them too.
"My husband usually hooks it for me because I like mine pretty tight," Zolciak told ET about her corset. "I get a lot of negative comments -- 'You've gotten too small!' -- [but] how can your waist ever be too small? That's what I'd like to know."
