Kim Zolciak is clearly proud of her post-baby body! Six months after welcoming her fourth child, son Kash Kade, the former Real Housewives of Atlanta star shared a sexy picture of herself via Instagram on Wednesday, Feb. 20.

"I'm obsessed with Have Faith swimsuits," 34-year-old Zolciak wrote in the caption. In the image, the "Tardy for the Party" singer models the label's $169 halter-style one-piece, which features a deep V-plunge and open back.

Zolciak and her husband, Kroy Biermann, are also parents to 17-month-old son Kroy Jagger, whom they refer to as "KJ." The Bravo reality star is also mom to daughters Brielle, 15, and Ariana, 11, from previous relationships.

In a November 2012 interview with Us Weekly, Zolciak said she got her post-baby body back in record time. "I gained probably 35 pounds and I lost it all in two weeks," she admitted. "I just don't stress about it! It just kind of falls off, I guess. It's weird."

Zolciak added, "I don't work out at all. And I eat very bad! I do think breastfeeding definitely helps. But I am lucky!"

The "Google Me" singer -- who abruptly departed The Real Housewives of Atlanta in the middle of the show's  fifth season -- added that she's contemplated having more children with 26-year-old Biermann, who plays defensive end for the Atlanta Falcons.  "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!" she told Us. "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!"
