Kim Zolciak is pregnant with her third child with NFL star Kroy Biermann, and the couple are living a happy newlywed life. However, Kim has two daughters from a previous marriage, and while bringing kids into a new relationship isn’t always easy, Kim says Kroy did everything right. He recently adopted the girls as his own, making them a family of 6 1/2.

“My daughters are very smart…I didn’t bring everyone around them,” Kim said. “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. I don’t know if I could love anybody else’s children as much as Kroy loves the girls. I just don’t know if I have it in me.”

Along with 16-year old Brielle and 12-year old Ariana, the couple are also parents to Kroy Jr. and Kash Kade. Biermann says his life is completely different now, but in the best way.

“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.”

Of course, it wasn’t just the girls who approved of Biermann from the start; Zolciak says she knew from the beginning that Kroy was the one.

“When I saw his butt, I have never in my life seen a butt like that,” the “Real Housewives of Atlanta” star said. “I just thought, ‘Wow he’s got a really cute butt and a million-dollar smile.’ With Kroy, it was just real. It worked from the very beginning.”
