‘RHOA’ Star Kim Zolciak-Biermann Posts Photo Of Son, But People Freak When She Says He’s Only 6

Kim Zolciak-Biermann recently posted a photo of her son on his way to school, and commenters cannot believe how big he looks.

The Real Housewives of Atlanta star shared the photo to Instagram earlier this month. It shows her 6-year-old, Kash, in a booster seat in the car.

"My baby @kashbiermann on the way to school this morning! He is such a BIG BOY he is only 6," Kim wrote. "He melts me his heart is unreal."

In response, fans couldn't help but comment on how old Kash looks for his age. Many wrote that the little boy looks like a teenager — or, shoot, a fully grown adult — rather than a 6-year-old.

"He looks like you're dropping him off at work," one fan wrote.

"Is this a clown car? He CANNOT be 6 years old!!" another wrote.

Kim shares Kash with her husband, Kroy Biermann, a former Atlanta Falcons player. That's probably where Kash gets his shockingly large size.

The couple also shares five other children — Brielle, 21; Ariana, 17; Kroy Jagger, 7; and twins Kane and Kaia, 5.

When she's not on reality TV or launching a new product, Kim Zolciak-Biermann is busy raising her six kids.

Kim and Kroy also have four more children together.

And then there's Kash, 6, the Big Boy in question.

Recently, Kim shared a photo of her middle son Kash on his way to school in a booster seat.

Indeed, commenters could not get over just how BIG Kash looks in this photo.

Many fans exclaimed that Kash already looks 12 or 13, which is twice his actual age!

Some went a step further.

They wrote that Kash looks decades older than he is.

Honestly… they're not wrong.

Many pointed out that Kash probably takes after his tall, football-playing father.

It's just that Kash is catching up to his dad a little more quickly than you'd expect.

One hilarious commenter even said that the 6-year-old looks like a "congressman in a booster seat."

Another said he looks like he could easily do all of our taxes.

For her part, Kim took the joking comments about Kash's large size in stride.

"Crazy right!" she responded to one commenter who said Kash looked "grown."

In response to the "favorite liquor" comment, Kim simply said "omg" with a ton of laughing emojis.

And as for that booster seat, which 46-year-old Kash may or may not need at this point in his long life?

"I'll keep them in one until they are 18," Kim laughed.
