Kim Zolciak's Botox Confessions During Daughter's TMZ Photog Trial

Kim Zolciak's daughter, Brielle, could have a career as a TMZ photog ... at least based on this video of her hammering mom with plastic surgery questions.

Kim and the fam were at LAX when we decided to give Brielle a trial run behind the camera -- and she hit up Kim about some pretty obvious changes to her face.

No joke ... Brielle seems like a natural who even hit up stepdad Kroy Biermann about his future in the NFL. But you gotta see his reaction to the grilling ... same for her little bro.

Entertaining brood for sure.
