The 2015 Billboard Awards were full of mimed performances, but Meghan Trainor and John Legend came through with a stellar vocal performance of their duet, "Like I'm Gonna Lose You," the third single from Trainor's album.

Trainor, wearing a dramatic, black A-line gown, kicked off the song before Legend joined her on the stage for the sweet ballad.

After the performance, Billboard Awards co-host and Legend's wife Chrissy Teigen revealed a playful envy towards Trainor's lovey lyrics towards her husband. "I'm a little jealous," she said.
