Luke Hemmings and Ashton Irwin from 5 Seconds of Summer have been best buds for a while now. Luke recently shared that even before the guys were friends, Ashton still had his back - AWW! Luke dished that he was being picked on for a recent hair cut and Ashton stuck up for him. "I was with some people that I didn't really like too much and Ashton was along with them. I didn't know him then 'cause I didn't know if I liked him or not... the people that I was with - I'd just got a haircut and they were teasing me about it. Ashton was like, 'leave the boy alone,'" Luke reveals. That story just warmed our hearts! Ashton is just too sweet. What do YOU think of Asthon sticking up for Luke before they were even friends?
