The battle between Kim Zolciak and Kroy Biermann started last week, arguing over finances

The newfound happy times between Kim Zolciak And Kroy Biermann were very short-lived, in fact, just a few days after celebrating their 12th anniversary, they were at each other’s throats… TMZ has learned.

Sources familiar with the situation tell TMZ that it has now been about a week since Kim and Kroy started having problems in their marriage again. We’re told the fights were, as usual, intense and revolved around their horrific financial situation and its impact on their relationship.

Translation: back to the common theme that led Kroy to file divorce papers, in the first, and second place.

We’re told Kim and Kroy remained under the same roof while they sparred verbally, and things continued to bubble between them.

We’re told that during the last bout of fighting, Kroy remained in the first bedroom and Kim was in the basement/nanny suite — as ordered by a judge — but that distance wasn’t enough to keep the peace.

Everything came to a head Monday night when one of the estranged couple’s youngsters children called the police during an “extremely loud” fight between the two. Law enforcement sources tell us three officers and a supervisor came to the house to take care of business, but no one has been arrested.

Interestingly enough, Kim and Kroy were been traveling with their children for a haircut and a few Starbucks just hours before the police visit, and all seemed calm.

The drama is a 180 degree departure from what the couple portrayed on social media when they met celebrated their wedding anniversary on November 11 with a luxurious meal and drinks… seemingly oblivious to the crowd money misery they continue to be confronted.

Speaking of their financial problems…Kim and Kroy’s mansion in Georgia, which was kind of the point go up in a foreclosure auctionis still on the market for $6 million.
