IIt's one big, happy, legally recognized family at "Real Housewives of Atlanta" star Kim Zolciak’s home these days, now that her husband of two years has officially adopted her two daughters. Atlanta Falcons defensive end Kroy Biermann told E! News this week that he adopted Brielle, 16, and Ariana, 12, out of a sense of family priority. "In order to keep balance you have to have priorities," said Biermann, who is also dad to two sons with Zolciak. "Our careers are our priorities, our kids, our health, our happiness ...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."
