Brielle is Kim’s eldest daughter and her biological father has never been revealed, while Ariana’s father is Kim’s ex-husband Daniel Toce.

Two years after Kim and Kroy’s wedding in 2011, the former NFL player adopted both of Zolciak’s daughters.

Kim also shared a short birthday video on Instagram of her sitting at a table with friends and blowing out a candle.

The sweet birthday greetings come after Kim and Kroy shocked the world when it was revealed the couple had split after 11 years of marriage.

The “Dancing With the Stars” graduate and the former NFL player had a famously tumultuous romance: They got engaged and had their first child within three months of meeting in May 2010.

The couple went on to have three more children together, and all the ups and downs of their torrid romance were documented for the cameras on hit reality show Don’t Be Tardy.

Living their torrid sex lives together, building businesses and struggling with numerous financial issues, the pair reportedly owed the IRS $1.1 million in unpaid taxes.

Zolciak is still living with Biermann at their Georgia home after filing for divorce, but the exes are “avoiding each other,” a source told Us Weekly.

According to a source at People, the main reason for their split seems to be their financial problems.

The insider revealed that Kim had been planning to break up with Kroy for “a long time” and hadn’t told family or friends about it.

“The money was a big problem.” The million tax [payment] It was just way too much pressure on them,” the source said.

It also added, “There’s no cheating on either side.” The money has a lot to do with the breakup, but there were other factors as well. He can do it [the family] for a long time, so technically he had a job. They don’t get along well at the moment.’
