Chris Daughtry was absent from the big "American Idol" reunion during the finale -- but this weekend he was joined on stage by one "AI" alum, Kelly Clarkson!
The OG "Idol" sang Tracy Chapman's "Fast Car" with Daughtry at his Nashville concert Sunday night, and the duo sounded incredible.
During the show, Chris was also joined on stage by Jason Wade of Lifehouse and later by Three Doors Down frontman Brad Arnold.
