Just days after having twins, Kim Zolciak is back to her pre-baby body.

The former "Real Housewives of Atlanta" star, 35, gave birth to twins less than two weeks ago, and today, her daughter gave fans a glimpse of her post-baby body.

"HOW" Brielle Biermann posted on Twitter, along with the above photo.

Zolciak, who has two sons with her husband, NFL player Kroy Biermann, and two daughters from previous relationships (whom Biermann adopted), retweeted the sentiment.

"How is my mom a size 4?" Brielle asked. "It's been 9 days since she gave birth to twins."

Zolciak gave a clever response to which most moms can relate: "From chasing after you!"
