Kim Zolciak Debuts "An Ab" After Six Kids

Kim Zolciak is looking healthy and fit just four months after giving birth.

On Instagram, the Don't Be Tardy star and wife of Atlanta Falcons player Kroy Biermann shared a photo of herself with her belly out, and after six children, her figure is quite impressive.

"I think I see an ab!!!! hey after 6 kids I'll take it!!" Zolciak, 35, captioned the photograph, according to a March 26 report by E! News. In the photo, the mother of six is seen lifting up her shirt, baring her midriff as she stands to the side in tight black leggings.

In Nov. 25, 2013, just two years after she and Biermann got married, Zolciak gave birth to their third and fourth child, the fifth and sixth for Zolciak, who is also mom to Brielle, 16, and Ariana, 12, both from previous relationships.

In addition to twins Kaia and Kane, Zolciak and Biermann are also the parents of sons Kroy Jr., 2, and Kash Kade, 1.

As for how she's lost the baby weight, Zolciak recently came forward, revealing that she was using the dietary supplement, Xenadrine.

"I take Xenadrine for energy to work out and do an hour of cardio each day," she told Life & Style on Jan. 30, 2014, adding that although she doesn't allow herself to get on the scale, all of her pre-baby clothes fit.
