She had a bulging belly just weeks ago, but now, former “Real Housewives of Atlanta” figure Kim Zolciak is already showing off a slimmer waist after giving birth to twins. The 35-year-old posted a photo of herself of Twitter along with the caption, “My belly is almost gone!!!”

While she is wearing all black, which is slimming, it is certainly clear that the new mom has already lost a ton of weight. As of late, new mothers have been quick to show their post-baby bodies off on social media, and one, Caroline Berg Eriksen, sparked outrage in the media after showing off her slim figure just nine days after having a baby.

Zolciak gave birth to her twins, a boy and a girl, on Nov. 25, and her belly measured 48 inches at the end of her pregnancy. The twins join Brielle, 16; Ariana, 11; K.J., 2; and Kash Kade, 1. Now that she has such a large family, Zolciak promised that she is done having children at this point.

In July, her husband, Kroy Biermann, legally adopted Zolciak’s children Brielle, Ariana, and K.J. from a previous relationship. She and Biermann, now 27, met in May 2010 at a charity function in Atlanta. However, the reality TV star stated that she wasn’t looking for a relationship at the time. “I had my daughters, and so if I never got married and didn't have any more kids I was kind of OK," she said. "It wasn't like I was out there going, ‘Oh, my god, my time clock's ticking, I gotta have children, and I gotta do this.' I didn't have that."

However, the two quickly fell in love and later married in 2011. After getting hitched, Zolciak told E! News her two daughters approved of Biermann “almost immediately.” The feeling was mutual. "I don't know if I could love anybody else's children as much as Kroy loves the girls," Zolciak said. "I just don't know if I have it in me."
