KJ stands for Kroy Jagger—yes, like the Rolling Stones legend. His full name is Kroy Jagger Biermann, and he was born on May 24, 2009.
He’s the second-oldest of Kim and Kroy Biermann’s four kids. But wait—he’s also part of a mega-blended family with Kim’s older daughters, Brielle and Ariana, from her previous relationship.
So, technically, he’s smack-dab in the middle of a house that looks like a reality show on steroids. And honestly? He handles it like a champ.

Here’s the thing: KJ isn’t famous just because his mom wore a wig on Bravo. The kid is a legitimate football star in the making.

He plays quarterback for his high school team, and his highlight reels are wildly impressive. I’m talking spiral passes, lightning-fast footwork, and a confidence that screams, “My dad played in the NFL.”
His dad, Kroy Biermann, was a defensive end for the Atlanta Falcons. So, yeah, the football genes are strong with this one. Very strong.
The Social Media King (or at least a prince)
If you’re on TikTok, you’ve probably seen KJ doing dances, pranking his siblings, or just being a goofball. His account is a mix of sports, sarcasm, and sibling chaos.
He’s got a laid-back, “I’m too cool for school” vibe, but then he’ll post a video of him and his little brother, Kash, wrestling on the floor. It’s adorable, I swear.
And yes, he’s been caught in the Kim Zolciak “trying to film me while I’m eating” trap. We’ve all been there, KJ. We’ve all been there.
