Their harmonies blended perfectly on the feel-good song.

The two, who won every award they were up for, showed off their artistry with a rendition of "I Should Probably Go to Bed."

The duo turn a white Christmas blue with the reflective new song.

The song is the country duo's first new release since "10,000 Hours" with Justin Bieber hit No. 1 in January.

While in Miami, Fla., for the Super Bowl, Lovato hopped onstage with Dan + Shay to perform their song "Speechless."

Kelsea Ballerini, Dan + Shay and Blanco Brown are among the performers for 'Dick Clark's New Year's Rockin' Eve'.

Dan + Shay have announced a slate of arena tour dates for 2020.

Don't worry, we asked.

What a crazy surprise wedding.
