Check Out a Teenage Kim Zolciak-Biermann in This Precious Throwback Pic

We might be just days into a new year, but Kim Zolciak-Biermann is reminiscing about her past. And as a subtle reminder to everyone that she made for a pretty adorable teen, the Don't Be Tardy mom shared a photo from when she was a fresh-faced 15-year-old. The snapshot features the teen with one of her BFFS, showing off her big smile. And she notes that in those days, "#IReallyThoughtIWasSomethingBackThen." 

If there's anything we really learned from this pic, it's that "#PhotoBoothsWereTheBomb." True that, Kim.
