Meghan Trainor and John Legend [1] both have excellent voices, but you might be surprised at how beautiful they are together. They teamed up for a duet of their song, "Like I'm Gonna Lose You," off Trainor's debut album, Title, at the Billboard Music Awards [2]. This is the perfect song for people who might be a little burnt out on Trainor's bigger hits like "Lips Are Movin'" and "All About That Bass." It's a slow ballad, and it's beautiful. Watch below, and check out Nick Jonas's performance of "Jealous." [3]
