Love triangles? Old news. Love squares are apparently the new rage … ’cause Kroy Biermann was gettin’ cozy with Jillian Green … who just so happens to be the ex-wife of his ex Kim Zolciak‘s current BF, Kyle Mowitz … got all that?!

Check the pics — Kroy and Jillian were spotted hiking together in Alpharetta, Georgia over the weekend — and judging by the smiles, hugs and very couple-y energy at the end of their 3-hour trek, this wasn’t exactly your average everyday cardio session.

Now, Jillian’s ex is Kyle — the same guy Kim started dating back in Spring 2025 — meaning everybody’s apparently swimming in the exact same Georgia dating pool … which is kinda weird and messy.

TBH, we’ve seen this playbook before — remember, T.J. Holmes and Amy Robach are now dating each other — with their exes finding their way to each other not long after.

As of now, Kroy and Jillian haven’t confirmed a romance … but based on these pics, it’s feeling way less like “if” and a whole lot more like “when” … especially once you factor in the instant trauma-bonding and inevitable story-swapping over their respective exes.
