Kroy Biermann bonded with Jillian Green — the ex of his estranged wife Kim Zolciak’s boyfriend, Kyle Mowitz — during a flirty outing over the weekend.

The retired NFL player, 40, was spotted hiking with Green on Saturday, in photos obtained by Page Six.

The duo, both sporting black athleisure and sneakers, were all smiles during the Alpharetta, Georgia, outing.

The pair even shared an embrace.

Reps for Zolciak and Biermann did not immediately respond to Page Six’s requests for comment.

Biermann and Green are navigating respective divorces from Zolciak, 47, and Mowitz, who went public with their romance in October 2025.

The latter couple has reportedly been together since last spring.

When Biermann found out about the relationship, he met with Green at her cousin’s home and issued a scathing warning about Zolciak’s spending habits.

The former “Real Housewife of Atlanta” star was “not bothered at all” by the pictures of her estranged husband with Green, TMZ reported Monday.

She and Biermann wed in November 2011, with the former athlete adopting her two eldest daughters from a previous romance — Brielle, 29, and Ariana, 24.

The couple went on to welcome Kroy “KJ” Jr., 14, Kash, 13, and twins Kaia and Kane, 12, before calling it quits in 2023.

While Zolciak and Biermann have reconciled multiple times during their contentious legal battle, they last split in 2025.

Their tumultuous breakup, which has included accusations — and denials — of cheating and abuse on both sides, is still playing out in court.

Most recently, Zolciak was stripped of primary custody of their children and granted limited parenting time every other weekend ahead of their next court date on May 21.

As for Mowitz and Green, the exes filed for divorce in March 2025 after nearly eight years of marriage.

Green claimed this week, per TMZ, that Mowitz’s spending has been “out of control” amid his romance with Zolciak, alleging he pays for the Bravolebrity’s legal fees, trips, wine and more.

Last year, Green subpoenaed Zolciak for documents related to her financial relationship with Mowitz — a move the reality star dubbed “unreasonable” and “oppressive.”
