Kim Zolciak is cutting every possible tie she can with estranged husband Kroy Biermann — including his last name!

The Real Housewives of Atlanta star noticeably removed her surname from her Instagram account more than a month after officially filing for divorce from her spouse of 11 years.

The swiping of her past from her social media handles comes as insiders close to the former couple admitted Zolciak and Biermann have been at each other's throats as they continue to live together in her Georgia mansion with their children, Kroy Jr., 11, Kash, 10, and 9-year-old twins Kaia and Kane.

"Kim and Kroy are living in different sides of the home, crossing over in the kitchen yelling and screaming at each other in the night," the source spilled. "They both want the house and everything in it, including expensive art pieces and furniture. They’re even bickering over knickknacks. Kim’s being petty and Kroy’s being a jerk."
