Ariana Biermann is looking all grown up these days. Not to mention the fact that she's blossomed into a double for her Don't Be Tardy mom, Kim Zolciak-Biermann. Kim proudly showed off how much her little girl is growing up to look like her on Instagram.

Her more mature look is hardly shocking since Ariana certainly has taken some big steps in her life in the last year. She got her driver's permit back in May and last summer she got her braces removed. If you want to see more of Ariana and the family, be sure to tune into the premiere of Don't Be Tardy on October 6 at 8/7c. Check out a preview of the hijinks to come above, and check out some vintage Ariana below.
