AceShowbiz - Is Kim Zolciak eating for two? The "Don't Be Tardy..." star sparks pregnancy speculations after her own daughters Brielle Biermann and Ariana Biermann appeared to hint at it in recent Instagram video.

The said video, which was recorded by Brielle, featured Brielle asking Ariana to give their Instagram followers a tour of what seemed like a hotel room. "Take us around, Ariana," Brielle could be heard saying to her sister.

Later, Kim was briefly featured in the video while donning a pajama. "She's pregnant 3 months," Ariana said of her mother. Kim appeared to nod in agreement, while Brielle was laughing.

It remains to be seen whether or not they were serious about the whole thing. Should Ariana tell the truth, the baby will be Kim's 7th child and her 5th child with husband Kory Biermann.

Neither Kim or her daughters has commented on the claims.

This is not the first time Kim was rumored to be pregnant with baby No. 7. Back in 2017, the former "The Real Housewives of Atlanta" star was hit with the rumors after Brielle decided to troll on Twitter. "OMG!!! i'm so excited my mom is PREGNANT with baby number 7!!!! OMG!!!! i can't wait to meet the little nugget inside. it's been so hard keeping this a secret!!! wooo!! #lucky7," so she wrote, adding that herr mom was "due in the springt sometime!"

Kim then set the records straight on Snapchat. "Brielle's lying!" Kim insisted. "She's lying."

Whether or not Kim is having another child, she is currently living a happy life with her family. During last Halloweeen, Ariana honored her mom her mom's famous Playboy bunny costume, much to Kim's delight.

"My baby @arianabiermann wore my Playboy Bunny costume this weekend! I love it! costume by @vintageinspiredbyjackie," so Kim wrote on an Instagram post featuring the 18-year-old looking sexy in the costume and some pics of herself in the same costume, which consisted of a black bodysuit with a black and white bow tie neck piece, black bunny ears and a bunny tail.
