Kelly Clarkson is revealing her secret to keeping it composed onstage!The season 23 Knockout Rounds continued on Monday's, and things got emotional when Team Niall's Ross Clayton and Jerome Godwin III took the stage with their respective performance of Steely Dan's «Dirty Work» and «Someone You Loved» by Lewis Capaldi.The coaches were pretty unanimous in their opinions, saying that while Ross' rocking cover was nearly pitch-perfect, Jerome may have made a misstep when he chose a ballad instead of his usual uptempo performance.When it came to offering her comments to Jerome, Kelly said she felt the young singer and dental student had a «wall up» and didn't show as much emotion onstage as she hoped he would.«Sometimes, I feel a song so much that I have to go dead inside,» she explained of her own process.
