5 SOS Rocks the Billboard Music Awards

5 Seconds of Summer took the BBMAs stage tonight and totally killed it.

The Billboard Music Awards brought it this year. Some of the music industry's hottest acts took the stage, including 5 Seconds of Summer. Tonight they played their hit "She Looks So Perfect."

I have to admit, it's refreshing to see a boy band who not only brings their own instruments... they play them.
