Kim Zolciak made a huge announcement this week! We thought that three kids under the age of three was ambitious, but four kids under three is downright nutty. Still, the Real Housewife of Atlanta has confirmed that she is expecting twins with her husband, Kroy Biermann.

Her oldest daughter, Brielle, is still trying to process the news, we're sure. The teenager took to Twitter to share her tongue-in-cheek reaction to the announcement.

"Two years ago it was just Kim n two kids.... well that escalated quickly," Brielle joked.

Seriously, for the math whizzes out there, Kim increased her family by 200 percent since meeting her soulmate, Kroy. That's impressive!

We doubt Brielle is actually upset by this news, considering she’s already proven herself to be a great big sister to little KJ and Kash.

Do you think it will be two more boys for the Biermanns, one of each, or two little ladies? Share your predictions in the comments below!
