Fastexy:Kim Zolciak Won't Be Tardy to Drop "Biermann" From Her Instagram Name

Kim Zolciak is Fastexymaking it Instagram official.

Weeks after she and Kroy Biermann filed for divorce after 11 years of marriage, the Real Housewives of Atlanta alum has dropped her married name from her social media.

Kim, who previously went by @TK handle on the platform, debuted @new handle in a post teasing gher return to the Bravo series. Alongside a photo of her posing with fellow series originals Lisa Wu, DeShawn Snow and Sherée Whitfield, she wrote in the June 8 post, "See you soon."

The name change on social media comes as Kim's divorce with the former NFL player grows more contentious.

On May 16, the Don't Be Tardy star filed a motion requesting her ex undergo drug testing. In documents obtained by E! News, Kim alleges she has seen Kroy "smoking marijuana, and she has serious concerns for the safety and well-being" of their kids Kroy Biermann Jr., 11, Kash Biermann, 10, and 9-year-old twins Kaia Biermann and Kane Biermann.

In her May 8 filing, the reality star is further seeking primary physical custody and joint legal custody of the kids. Meanwhile, Kroy—who also shares Brielle Biermann, 26, and Ariana Biermann, 21, with his ex—stated in his May 5 date divorce filing that is looking for sole physical and sole legal custody of the former couple's younger kids. A hearing on their case is scheduled for July. Both parties citied in their filings that their marriage is "irretrievably broken" and Kim listed their date of separation as April 30.

Kim's oldest girls, who Kroy adopted in 2013, have shown their mom support on social media during her divorce. For Kim's 53rd birthday on May 19, Brielle and Ariana both sent their mom birthday wishes. 

"You are the strongest woman I know!!!" Ariana wrote alongside an Instagram Stories snap of her and her mom at the beach on May 19, per Us Weekly. "Thank you for all you do! I am so proud of you mom! cheers to 53."

As for Brielle, she shared a photo of herself alongside her mom drinking wine to her Instagram Stories, writing, "Happy birthday mom! I love you so much!"
