Nick Jonas hit up the Billboard Music Awards on Sunday and brought the house down with a rendition of his hit "Jealous." The full light show is very '80s, and he even has a metallic windbreaker to complete the scene. Despite how retro it sounds, it actually feels pretty modern. The lights are great, but Jonas's vocals are the highlight of the performance. He really is a supremely talented singer! Watch the video below, and watch One Direction thank their "brother Zayn" while accepting their award.
