"I've had covid (still recovering but I'm doing good today!!)" she wrote in one slide, adding in a subsequent video that she is "beyond bored" from being in quarantine, and asked her followers for TV show recommendations.

"Shoutout to Kroy who has been delivering me my necessities at the stairs. He's been bringing me all my clothes and food. He even brought me milk and cookies the other night," Brielle said of her step-father Kroy — though Kim later clarified on her Instagram Story that it was she who provided the sweet treats.

 On her own Instagram Story, mom Kim said she was "very stressed" following Brielle's diagnosis. 

In addition to Brielle, Kim is mom to 19-year-old Ariana, both of whom Kroy adopted after he and Kim wed in 2011. The couple also shares sons KJ, 9, and Kash, 8, and twins Kane and Kaia, 7.

As of Wednesday, it seems none of her other children have tested positive for the virus.
