Kim Zolciak Tweets About “Big Day” For Her Family — What’s Going On?

Usually, our Real Housewives of Atlanta like to spill their every thought and bit of good news on Twitter, but Kim Zolciak's latest post left us in a state of suspense. What could she be talking about?

The mama of four shared, "today is a big day for our family! can't wait to tell you guys!!!!!" The happy message was accompanied by the above picture of Kroy and, we must say, a very young-looking Kim, sitting in a car. Both look super content.

Was it moving day for the Zolciak-Biermann's? Did Kroy finally adopt Kim’s girls? Is another baby Biermann on the way? Share your theories in the comments below!
