Hello I'm Katie Liz Hemmings yes luke Hemmings from 5 seconds of summer my brother is over protective of me. If he found out I was with someone he would hurt them if they ever did anything to me and one thing I'm 17 I'm Luke's twin but we don't tell any one about it we even told are mother not to say anything about it we just never wanted to tell anyone and I don't see how were twins we looks nothing alike
