If you're not following Kim Zolciak and Kroy Biermann's eldest daughter Brielle Biermann on Instagram, do yourself a favor and fix that. We've watched the blonde beauty grow up over the years on Bravo's Don't Be Tardy and Real Housewives of Atlanta — and her latest selfies are clear indicators that she's transforming into a stunning young woman.

The newly single 21-year-old has made headlines over the years thanks to her enviable bikini body and striking facial features — much like her famous mother, Kim. Though every so often she has to put the haters in place, it's clear Brielle is living her best life. While we wait for another season of Don't Be Tardy, we'll have to stick with social media to keep up with the reality star and the rest of the Zolciak-Biermann clan.
