Kim Zolciak-Biermann's daughter Ariana Biermann has transformed from a kid to a young lady right before our very eyes over the years on The Real Housewives of Atlanta and Don't Be Tardy. If you need any further proof of that, we've got it: Ariana is now a high schooler.
The Don't Be Tardy daughter started high school on Monday, and Kim is just as shocked as we are about how fast the years flew by. "I can't believe these two started high school today!! @arianabiermann slow down. [W]here does the time go!!" Kim captioned a pic of Ariana and a friend on their first day of school Monday. "I can only imagine all that you accomplish these next 4 years! My athlete, (volleyball) My cheerleader, My honor roll student, My biggest helper with the biggest heart. We love you so much. We are so proud of you!"
And Ariana isn't the only kid in the Zolciak-Biermann household who's moving on up in school. Kim revealed in the hashtags of the Instagram post that next week, her son KJ starts kindergarten and another son, Kash, will turn 4 years old and begin pre-K.
With her six babies quickly growing up, Kim hinted that she wants to have another child with husband Kroy Biermann, writing "#KroyOneMore" in the post, a desire she also expresses in the supertease for the upcoming fifth season of Don't Be Tardy premiering Wednesday, September 14 at 10/9c.
