Avert your eyes, Brielle!

Kim Zolciak and Kroy Biermann's oldest daughter got a little more than she bargained for when she agreed to photograph her mom and stepdad for Valentine's Day.

Brielle was kindly taking photos of the couple in front of their Christmas tree (in February, yes), when Zolciak got a little handsy with her husband, grabbing his crotch.

"Goodbye," Brielle shouted on Snapchat. "What the f**k!"

Though the 19-year-old was horrified by her mom's PDA, Zolciak apparently found the photo charming, later posting it to Instagram.

"And to all a goodnight.... ❤," she captioned the photo.

This isn't the first time Zolciak has embarrassed Brielle on social media. In October, the Don't Be Tardy star posted a NSFW nude photo of her husband to Snapchat and shared Brielle's not-so-enthusiastic reaction.

"Dude what the f**k delete this bullsh*t," Brielle wrote in response to the racy pic.
