The “Don’t Be Tardy” star, 23, responded “thank you” to a fan who wrote, “The comments of her sitting on her Dad’s lap is disturbing and to say have they hooked up, like what is wrong with you people. He’s such an amazing example of what it’s like to take care of and love children like his own.”

Kroy married Kim Zolciak in 2011 and in 2013 adopted her two daughters — Brielle and Ariana — from a previous relationship. Kroy and Kim also have four children of their own.

Brielle posted the photo of her and Kroy for his birthday, writing in the caption, “I couldn’t imagine a life without your hardworking, selfless, loving, caring self! I’m so proud of you and all you’ve accomplished 🤍 .”

She also shared a second pic that included Zolciak, 42, while the family was out to dinner.

One person said to Brielle, “Tell me they haven’t hooked up,” to which she replied, “Do you hook up with your dad?”

When another fan asked why the reality star chose to sit on Kroy’s lap, she wrote back, “honestly because I had no where else to sit we were making jokes the whole time about him being Santa it was comedy.”
