On Saturday night during one of her "The Butterfly Returns" concerts in Las Vegas, legendary vocalist Mariah Carey took a moment in between songs to help facilitate a wedding proposal—and it was sweet AF!

The boyfriend of one of Mariah’s backup dancers proposed to his partner on stage, and while Mariah’s dancer knew that his boyfriend was in the audience, he had absolutely no idea that his man would be invited up on stage to propose.

The diva tweeted that her backup dancer said...yes!

Watch the adorable proposal in the video below!
