"2 kids same recovery room! ? it's all good though had the best doctor!" Zolcaik wrote alongside a snap of herself and husband Kroy Biermann posing in between their kids. "Had to take a pic for @kashbiermann and @briellebiermann for memory sake. Tonsils and adenoids removed!"
"Onward and Upwards ⬆️ #ImTheBiggerBsby #GetItTogetherMama ❌⭕️," she added.
Brielle told ET on Tuesday that she has needed to have her tonsils removed for "many years now, but I loved finding excuses as to why I couldn't! Beyonce, the pool, filming... lol. [I] finally had to cave."
"[I'm] looking forward to a speedy recovery," she added, revealing that her mom was more nervous for the surgery than she was. "Mom's been stressed all day since Kash and I both got surgeries. I'm a very chill, zen person so I wasn't nervous at all."
For now, however, Brielle's parents have been great nurses as she recovers -- and her boyfriend, Michael Kopech, will be spending his one day off next week traveling to take care of her.
Kash has spent quite a bit of time in the hospital this year, after his "traumatic" dog bite in April. See more in the video below.
