He still looks so perfect... Ashton Irwin might be super, super tired, but that's not stopping the 5 Seconds of Summer drummer from posting silly selfies to Instagram. "Feelin super tired, big big week ahead," he wrote on Instagram. "let's smash it, love you guys, you rule..." AWW! Even though Ashton's really exhausted, he still manages to tell his fans how much he loves them. You're the best, Ashton!
