Kim Zolciak
has a message for the haters!

The mother-of-six posted a selfie earlier this week, showing off of her amazing post-baby body.

But, the former "Real Housewives of Atlanta" star received some backlash from the pic, with critics asking for a front photo of Zolciak's fit figure.  

Well, she complied! 

"For all the peeps that had sh-t to say about my side profile post (the one of my one ab) and questioning what I look like head on... here is a head on pic taken just now! #eatyourheartsout #genetics," she captioned the candid snap. 

Yep, the 35-year-old really does have abs! Can you believe she gave birth to twins(!) just four months ago?

Call it whatever you want, Kim -- but those abs are definitely the result of hard work!  How to you think the reality star looks?
