Earlier this week, Montreal quartet Quartom got the opportunity of a lifetime. Not only did they get to meet Canadian pop icon Céline Dion backstage at her Las Vegas residency, but they also got to sing for her. And even better, she joins in and harmonizes with them.
In what the group described as an impromptu moment after they posed for photos with Dion, whom they call "the Queen of Las Vegas," the group starts singing Thoinot Arbeau's 1589 composition, "Belle qui tiens ma vie." Dion soon gets swept away by the tune and joins in briefly.
Watch the quick but beautiful moment below.
