During a recent interview with E!, the mother of four opened up about the sweet relationship between her husband, Kroy, and her two eldest children. "I don't know if I could love anybody else's children as much as Kroy loves the girls," she said of Biermann. "I just don't know if I have it in me."

The NFL star and family man stated that when he met Kim and they started having a family, his life has changed significantly. "Before Kim and before the girls and before the boys, I lived a pretty regimented life," Biermann said. "I'd wake up, eat breakfast, go to work, come home -- it was pretty normal. Now, my house isn't going to be as clean as it was before, but it's not important. Those things are not important and it's all about prioritizing and understanding."

And Kroy and Kim aren’t the only ones excited about the adoption; their daughters are also thrilled about their new last name. Even before being adopted by Kroy, Brielle and Ariana, “almost immediately” approved of the new man in their mothers life. Kim explained that she didn’t bring other men around her daughters before she met her now husband, Kroy. "My daughters are very smart…I didn't bring everyone around them," the reality star explained of her life before Biermann. "The relationships I had were long-term, but sometimes my daughters would notice that the person I was dating, they were doing things to kind of win my daughters' over to get to the mom — it wasn't genuine. And my girls can see right through that crap. So with Kroy, it was just real…It worked from the very very beginning."
