We all know that Kim Zolciak-Biermann and Kroy Biermann's family is absolutely adorable. But we're sure glad the Don't Be Tardy matriarch reminded us just how cute her brood is by posting a throwback pic of Kroy with his "twin" — a.k.a. their now-5-year-old son KJ.
From this photo, it's definitely clear to see that KJ was "born with personality," as Kim points out in the caption. "He is seriously the funniest, most brilliant child," she wrote.
In another pic, 4-year-old Kash joins Kroy and KJ to look like a set of triplets.
Kim found these gems while on a flight after her romantic — albeit quick — reunion with Kroy up in Rochester, New York Tuesday as he gets ready to start the football season with his new team, the Buffalo Bills.
Watch Kim discuss Kroy's career move, below.
