Like mother, like daughter! Both Kim Zolciak-Biermann and her daughter Brielle Biermann both bared their bodies in separate Instagrams on Sunday.

While Zolciak posted her midriff-revealing snap while wearing sweatpants from the comfort of her closet, Biermann's post was a bikini pic from the Bahamas.

In the caption, Zolciak said she the sweatpants and tank top combo has been her look for five years. "Sooooo unless I'm working ... filming I mean or entertaining guests I wear this EVERY SINGLE DAY!" the Don't Be Tardy star, 38, said. "The second I can I put this hot little number on I do! I have worn this 'look' for 5 years ever since I was pregnant with Kj!"

Brielle, on the other hand, peered over her shades while flaunting her toned body in an orange bikini in the clear Caribbean waters.

The 19-year-old quoted rapper Lil Yachty lyrics in her caption: "when i go on vacay i might rent out the bahamas".
