Kim Zolciak-Biermann‘s son is growing up fast!
On Tuesday, theDon’t Be Tardystar, 40, shared a new photo on Instagram and Twitter of her and husband Kroy Biermann’s 6-year-old Kash sitting in the car.
In the photo, Kash was placed in a backless booster car seat and dressed in a grey fleece jacket and khaki pants with his hair dapperly styled back.
The mother of six hilariously responded to a fan who left a message about the first grader’s appearance. “Holy hell he looks 25!” the fan wrote with Zolciak-Biermann replying, “Oh your day is coming.”
Another fan commented, “He looks so grown lol,” to which the Bravo star said, “Crazy right!!”
“He does not look 6 , he’s going to be a big boy like his daddy,” wrote one fan.
“Holy cow he does look like he’s 14 or 15 yrs old!” an Instagram user wrote.
Another follower exclaimed, “Lord Kim I was about to say who is this grown man on booster seat. Wow. I think he’s gonna be tall.”
And yet another wrote, “He looks like a 15 year old in a booster! Omg.”
Meanwhile, others criticized Zolciak-Biermann for placing Kash in a booster seat for the car ride. “I’ll keep them in one until they are 18,” she jokingly said, later telling one fan: “See where the seat belt falls… he needs a booster babe.”
