Kim Zolciak and Kroy Biermann are divorcing after 11 years of marriage.

Documents obtained by Fox News Digital revealed the former NFL player filed a divorce petition May 5 in Atlanta "on the ground that the marriage is irretrievably broken." 

Zolciak filed her own petition the same day.

In his petition, Biermann claims "the parties have accumulated certain debts and obligations, during the course of this marriage," and he is seeking an "equitable division of same."

In addition to their marital woes, Kim and Kroy owe the IRS more than $1 million in unpaid taxes from 2013, 2017 and 2018, according to separate documents obtained by Fox News Digital.

In February, it was reported Zolciak and Biermann’s extravagant Georgia mansion was in foreclosure and set to go up for public auction in March allegedly due to Kim and Kroy defaulting on a $1.65 million loan they took out in 2012 against the property. However, the foreclosure auction was later canceled. 

The reality television star previously responded to rumors that her mansion was in foreclosure in November 2022 and expressed that she’ll "leave when she wants to."

"If you guys think I would let my home that we've put millions and millions of dollars into go for $257,000, you're an idiot, okay? For real," she told her followers at the time.
