Kim Zolciak’s ex Kroy Biermann once barricaded himself in the estranged couple’s master bedroom which forced the “Real Housewives of Atlanta” star to call the cops to help mediate the situation.

In a video obtained Wednesday by TMZ from an incident that took place last month, Zolciak, 45, can be heard telling Biermann, 38, while on the phone with a dispatcher, “I don’t want anything to do with you. I want to get into my room, sir.”

The “Tardy to the Party” singer later told police that she wanted authorities present because the former Atlanta Falcons player “threatened” her and “had been physical before.”

Once police arrived at the Georgia mansion, they asked a makeup-free Zolciak if she could “not exacerbate the issue” if they were able to get Biermann to open the door.

“I just want to sleep in my bed,” she assured them, as an officer also recommends she and Biermann “come up with some type of compromise.”

But getting Biermann to cooperate would prove to be more difficult.

He got into a back and forth with an officer after the offical told him, “If you continue down this road, it’s not going to go well,” later adding, “You are now making me feel very uncomfortable and unsafe.”

“I didn’t do anything to you,” Biermann said through the door, claiming that he felt his “safety [is] in jeopardy” when it’s just him and Zolciak.

Biermann has also accused his estranged wife of being abusive in the past.

Eventually, police are able to get Zolciak a comforter, phone charger, medications and neck cream from Biermann.

The Post has contacted reps for Zolciak and Biermann.

Zolciak filed for divorce from Biermann in May following 12 years of marriage.

They later decided to call off the divorce until Biermann filed again in August.

They share four minor children: Kroy Jr. “KJ,” 12, Kash, 11, and twins Kaia and Kane, 9, of whom Biermann requested sole legal and sole physical custody.

Zolciak recently tried to get the divorce dismissed again, claiming that she and Biermann are still having sex, but the former linebacker requested for the divorce to proceed.
