Kelsea Ballerini does epic job filling in for Kelly Clarkson on 'The Voice'

"The Voice" coach Kelly Clarkson was out sick for Monday's Battle Rounds. Out of an abundance of caution, and abiding by the show's covid-19 protocols, she was temporarily replaced by Kelsea Ballerini. Ballerini was her team advisor in season 16 and a coach on the show's short-lived online companion series "The Comeback Stage."

Viewers thought Ballerini did an epic job filling in for Clarkson, but the other coaches weren't fans of the two stars conspiring against them when it came to making tough decisions. Ballerini called the sick coach at one point to help her decide which contestant to keep on Team Clarkson.

And while Balerini did a great job as a fill-in coach, she was also a pretty good thief. She managed to steal Avery Roberson right out from under rival coach Blake Shelton.
