Ariana Biermann Just Debuted a Super-Glam Makeover

Ariana Biermann is proving that glam is definitely in the Zolciak-Biermann jeans, actually, make that genes. The Don't Be Tardy teen just debuted a super-sophisticated new look, growing up right before our — and Kim Zolciak-Biermann's — eyes. Kim shared that she's "not my baby anymore." In fact, she's looking more and more like big sister Brielle every day.

Need more evidence that Ariana isn't a little girl these days? Well, there is this other photo that Kim posted. And while Ariana didn't go into too much detail about her new look, she did have this to say about it: "back 2 blondee."
