Kim Zolciak is putting her daughter Brielle's phone on lockdown!
The former "Real Housewives of Atlanta" star grounded her 17-year--old after the teenager snuck a photo of her mom's derriere -- and then proceeded to share some nasty comments about it with her friends on Snapchat.
"Sooooo I'm in MY bathroom trying on some clothes I just got talking with my sweet beautiful @briellebiermann and all the while she is taking pics and posting on SnapChat," Kim posted on Instagram last night.
"THIS IS ONE OF THE PICS SHE POSTED! So my sweet Brielle is now grounded (she just got ungrounded last week) and now has no phone for a week," she added.
"#IDontHaveSnapChatSheThoughtIWouldNeverFindOut #IFindOutEverything #IDidLaughThough #SocialMediaStressesMeOut," she hashtagged the pic.
And yes, the quote "when ur moms ass is fatter than urs" is what Brielle wrote when sharing the photo ... how sweet, right?!
It's clear Kim is proud of her booty though, since she still shared the pic herself on her own Instagram account.
We gotta say, it does look pretty good. What do you think of the shot? Sound off below!
