Plus: The two "American Idol" alums team up for a "Silent Night" duet.
The two Kellys sprinkled some soul into their socially distant rendition of "Silent Night" from Tori Kelly's first Christmas album, A Tori Kelly Christmas, which she executive-produced alongside Babyface and Scooter Braun. But that's not the only Christmas song these two performed in front of their virtual audience.
Both American Idol alums put their voices to the test to see who could finish a Christmas song for a festive and aptly named Kelly Clarkson Show segment "From Kelly to Kelly." Black-ish actor and comedian Deon Cole stepped in as the judge for the friendly competition, which challenged both Grammy-winning artists to sing classic carols, including "Hark! The Herald Angels Sing," "O Christmas Tree" and "We Three Kings" line-by-line until one of them messed up a lyric.
