Kim Zolciak, best known as a personality on the Bravo series "The Real Housewives of Atlanta" gave birth to son Kash Kade just three weeks ago, but you wouldn't know it based on the new shot the reality star's daughter snapped of her on Twitter.

Zolciak wowed Twitter followers on Saturday when the casual photo of her was uploaded to Twitter, showing her standing in her home, wearing sweatpants and a tank top, and sporting a conspicuously flat stomach.

Kim's 15-year-old daughter, Brielle, was the first to tweet the photo, writing, "seriously ... who looks like this after 2 weeks of having a baby?" Kim responded, writing back, "Awe Thx love muffin!" with the hashtag "#sneakingpicsofme."

Despite complaining on Twitter that she desperately needed to find a new personal trainer, and had been hankering for sweets, the star looked like she had managed to get quite fit on her own.

Zolciak's son is her her fourth child, and her second with her husband, Kroy Biermann, and was delivered on Aug. 15, exactly nine months after getting married. The couple, who documented their wedding on Nov. 11, 2011 in Life & Style magazine, welcomed their first child together, 7months earlier, a son named Kroy Jagger, Jr. Zolciak also has another daughter, Ariana, 9, from her previous marriage with Daniel Toce Jr.

Unfortunately for Zolciak, the birth of her second son comes amid some turbulent family drama for the star. Last year, her ex-husband Toce was sentenced to serve 2.5 years at the MacDougall-Walker Correctional Institution, in Suffield, Conn., for sex abuse against a 15-year-old. Pending Toce's release he will be sentenced to 10 years probation, and will additionally be required to register as a permanent sex offender.

Since then, Zolciak has reportedly been wrapped up in trying to cut off his parental rights to her two daughters. And just recently, Zolciak faced legal action against her by her mother. Last week, Zolciak's mother, Karen, filed a petition against her in Georgia Superior Court, for visitation rights to see her grandchildren.

According to TMZ, Karen Zolciak is complaining that her daughter's reality show made her out to be a villain just to create added drama for the show, and strain their relationship. Kim's mom is alleging that she was kicked out of her wedding last year by the police, for using an indoor bathroom instead of a porta-potty.

Karen Zolciak's petition claims that being separated from her grandchildren will cause them "emotional or physical harm," and that "the girls live such a crazy, abnormal life being on T.V. ... they need a normal haven to relax."
