What is it like being Ashton Irwin's younger sister? Its not as fun as it seems. I mean don't get me wrong I love my brother and he's great but he's way over protective, and I can't go anywhere without people asking me thousands of questions about my brother and his band mates. My name is Lynn Irwin, I'm 18, my height is 5'7, I have hazel eyes, and I attended to dye my hair alot but at the moment I'm keeping it dark brown. My name is Lynn Irwin and this is MY story!
