Avril Lavigne turns 28 years old today – and what a year it's been for the Canadian rocker!
The "Sk8er" girl has had quite the career, filled with both ups and downs, in her short 28 years.
From her marriage and split with Sum 41 front man, Deryck Whibley, to her romance with reality star Brody Jenner and unexpected engagement to Nickelback crooner Chad Kroger, she's definitely made some headlines!
But personal life and singing career aside, she also has a successful fashion line!
Just this year, Avril's Abbey Dawn was a hit at New York Fashion Week -- where Kylie Jenner walked the runway and we got our first glimpse at her massive 14-carat engagement ring.
So in celebration of the always entertaining singer/designer/professional pop-rocker, we've pulled together her most memorable moments through the years!
