Wild child Avril Lavigne hit big in summer 2002 with her spiky-fun debut song, "Complicated," shifting pop music into a different direction. Lavigne, who was 17 at the time, didn't seem concerned with the glamour of the TRL-dominated pop world and such confidence allowed her star power to soar. The middle of three children in small-town Napanee, Ontario, Lavigne's rock ambitions were noticeable around age two. By her early teens, she was already writing songs and playing guitar.
