The duo won video of the year for "Hallelujah." Underwood, who extended her record as the most decorated artist in the history of the CMT Music Awards, accepted the nod on her and Legend's behalf.
"Thank you fans! Thank you CMT!" Underwood said. "You're the reason we're all here doing what we do, doing what we love (and) making music videos."
The 23-time CMT Music Award winner also shouted out Legend, particularly for sending her the song, which appeared on her first holiday album "My Gift." "Congratulations on what I think is your first CMT Award. Whoa!" she exclaimed.
