The Real Housewives of Atlantaalum came to the 20-year-old’s defense in an Instagram Story on Tuesday.

“Ariana was involved in a minor fender bender. When police arrived on the scene, the investigating officer immediately initiated an investigation for DUI of alcohol,” wrote Zolciak-Biermann, 44. “Despite Ariana’s constant invocation that she was upset and anxious from the minor accident, the officer incorrectly concluded she was impaired. That was not the case.”
