Dan + Shay doubled down on the vocals at the 2019 Billboard Music Awards, recruiting powerhouse singer Tori Kelly for an awe-inspiring performance of their heartfelt hit "Speechless."

First, Dan + Shay (Dan Smyers and Shay Mooney) showed off their impressive harmonies. Kelly then took things to the next level once she began the second verse, her voice soaring as Mooney joined in. The trio kept their performance simple, singing alongside each other in front of a subdued live band that put their voices at the forefront and left viewers, well, speechless.

Part of the Scooter Braun Projects family, Dan + Shay and Kelly were each nominated for multiple awards at this year's BBMAs -- and both came out winners. Kelly won top gospel album for her 2018 Christian project Hiding Place, also receiving nominations for top gospel artist and top gospel song. Dan + Shay were named top country duo/group before the show, and the pair received six other nominations, including top country song for "Speechless" as well as their other Country Airplay No. 1 of 2018, "Tequila."
