Despite any pre-performance jitters he might have felt on Sunday night (May 22), Troye Sivan failed to let them show. The South African-born singer made his debut on the Billboard Music Awards stage, performing his hit single "Youth" for the crowd with the ease of a seasoned professional.

Troye, who took the stage as the evening’s Kia’s One to Watch honoree, whirled about while delivering a pitch-perfect vocal performance of the 2015 track.
