During the tapings in early December, Clarkson tested positive for COVID-19 and had to quarantine and host from home. She also had guest hosts while quarantining.
"Have Yourself a Merry Little Christmas" in episode 62 (12 December) was performed by guest Jewel, marking the first time that a Kellyoke performance does not feature Kelly Clarkson. However, Kelly already performed the song in episode 58 (11 December 2020) of the second season.
