The reality star's daughter Brielle Biermann took to Twitter to make an announcement, 'OMG!!! I'm so excited my mum is pregnant with baby number 7!!!!!' she wrote in a now deleted post.
Brielle then shared the news on Instagram with the caption: 'OMG!!! I can't wait to meet the little nugget. It's been so hard keeping this a secret!!! woo!! #lucky7'.
A few minutes later, Zolciak shut down the story on her Snapchat.
'Brielle's lying!' she asserted. 'She's lying.'
It's not a hard to believe story though. Just last month Zolciak told Us Weekly that she and NFL husband Kroy Biermann regularly talk about expanding their family.
'I would love to have another little boy,” she told Us. “I am just obsessed with my boys.' The 39-year-old star added: 'I’m about to be 40 so I would like to hurry up if we’re going to do it, but I definitely think about it a lot.'
Zolciak has two daughters from a previous relationship, Brielle and Ariana.
Zolciak also shares four children with Kroy Biermann, Kroy, Kash, and twins Kaia and Kane.
