The picture included in the post is a photo of Underwood, 28, and Randolph, 24, cuddled up with smiles on their faces.
"I just want to take a second and thank this beautiful woman and her family for taking such good care of me," the reality star said. "Not only physically, but mentally too (and I’m probably the most high-maintenance patient). She’s hardworking, passionate, understanding, kind and has the biggest heart. Her family opened up their doors to us while we were in quarantine and through everything we stuck together."
Underwood then announced that he's "made a full recovery" from coronavirus and that Randolph and her family managed to maintain their health throughout the ordeal.
"I am now working with medical professionals to figure out the best way to support their efforts against the coronavirus," Underwood said. "I can’t thank @cassierandolph and the entire Randolph family enough for caring for me while I’m away from my family."
"There was a moment where I woke up at about three or four in the morning with the bed soaking wet from night sweats, and the symptoms of not being able to catch my breath hit me," he recounted. "I panic-bought oxygen on Amazon at four in the morning because I just didn't know how I was going to breathe."
