Kim Zolciak Is Not The Only Celebrity Mother With Shocking Weight Loss After A Baby: Check Out Alicia Keys, Halle Berry, And More [SLIDESHOW]
Kim Zolciak, a star on the reality show "The Real Housewives Of Atlanta," welcomed her second son with her NFL husband, Kroy Biermann, in August, and she is already flaunting her post-baby body.
In a photo she tweeted, Zolciak, 34, shows off her already shockingly trim arms and flat stomach, just two weeks after giving birth.
"Seriously ... who looks like this after 2 weeks of having a baby?" her daughter, Brielle Biermann, wrote, with a link to the picture.
When asked by Perez Hilton how she was able to regain her figure so quickly, Zolciak said, "No cleansing, I'm breastfeeding!"
Zolciak met Biermann, 26, during filming of the third season of "The Real Housewives Of Atlanta," and the two wed in their Atlanta home last November.
While Zolciak's weight loss is certainly surprising, she is not the only celebrity mother who quickly regained her former body after giving birth. Check out these photos of others, such as Mariah Carey, Jessica Alba and Halle Berry.
