iHeartRadio Awards 2015: Sam Smith Performs "Lay Me Down" (Video)

The four-time Grammy winner is nominated in five categories, including artist of the year.

Sam Smith took the stage at the Shrine Auditorium on Sunday evening to perform his hit "Lay Me Down."

Standing in the middle of a candlelit stage, Smith was backed by an orchestra and piano accompaniment as he belted the lyrics to the ballad. Host Jamie Foxx joked that he had to wipe away a few tears following the crooner's touching performance.

The soulful singer (along with Iggy Azalea) led nominees with five total nominations, including artist of the year and song of the year for "Stay With Me," and took home the award for best new artist.

The second annual iHeartRadio Music Awards took place at the Shrine Auditorium in Los Angeles on Sunday.
