And in the 20 years since she broke through with classics like "Complicated" and "Sk8r Boi," you'll notice she's always rocked a killer black smokey eye.
Which, turns out, she always does herself. "I just can't stand people doing my makeup, because I know how I like it. If anything, I do half of it or let them touch me up," Avril recently told Allure.
She added: "No one can do it right. Plus, I can't sit in a chair for an hour while someone's doing my makeup."
"It drives me nuts, especially when I can do my smoky eye in two minutes."
Avril's also been using the same eyeliner — MAC's Smolder — for 20 years. Though she's evolved her look. "I've learned over the years that you want to do some browns in there and some gray in with it, too. Then you use the black. If you just do solid black, it's really hard to get it a good shape."
She's also still practicing her liquid eyeliner skills — which, girl, same.
