Who Is KJ Biermann? Sorting Out the Names in Kim Zolciak’s Family

Why I looked up KJ Biermann

I wanted to untangle a basic question: is KJ Biermann the same person as Kroy Biermann? The similar names made me curious, so I checked Bravo’s own family profile and its guide to Don’t Be Tardy, rather than treating search interest as evidence.

The answer is no: KJ is Kim Zolciak and Kroy Biermann’s son; Kroy is his father. Both Bravo’s family profile and its show guide establish that relationship.

The names I needed to separate

Here is my reference table, based on those two Bravo pages. It is a way to keep the people straight, not a claim about why anyone is currently searching for them.

Name	Who it identifies in these sources
KJ Biermann	Kim and Kroy’s son; the family profile calls him Kroy Jagger “KJ” Biermann
Kroy Biermann	KJ’s father
Kaia Biermann	Kim and Kroy’s daughter, identified as Kane’s twin—not another name for KJ

The show guide also lists KJ among the family members featured in Don’t Be Tardy. That supplies the television connection without requiring speculation about a new event.

A practical example: reading an ambiguous caption

Hypothetical situation: suppose I encounter a caption that says only “Kroy Biermann” and assume it means KJ because I remember that KJ’s name includes Kroy.

I would leave that identification unresolved until the accompanying text supplies more context. The reason is specific: Bravo identifies the father as Kroy Biermann, while its show guide identifies the son as Kroy Jagger Biermann Jr. (“KJ”). A shared first name does not settle which person an unrelated caption means.

If the caption instead explicitly says “KJ,” that matches the son’s nickname in both sources. The useful distinction is the identifying wording—not a guess based on appearance or which name happens to be getting attention.

What I checked because I was still curious

The two official pages do not present KJ’s name identically. The family profile uses Kroy Jagger “KJ” Biermann; the show guide includes “Jr.”

My takeaway is to preserve that difference when attributing either wording, rather than presenting these entertainment pages as verification of a legal name. For this note, “KJ Biermann” answers the identification question without overstating what I checked.

These sources establish who KJ is and his connection to the show. They do not, by themselves, establish why his name is attracting attention right now. I’m keeping that separate from the family facts.
