5 Seconds of Summer made a splash with their US television debut on the 2014 Billboard Music Awards.
Calum, Luke, Ashton and Michael performed their infectious hit song “She Looks So Perfect” to the crowd and they did awesome for their debut. The guys looked awesome in their sleeveless rock gear and even Harry Styles was a fan.
@5SOS killing it at the @OfficialBBMAs …they're all so handsome. And sleeveless.
