Her hit songs skated into our hearts and helped define 2000s pop music.
In the video, the 36-year-old (yes, she's 36) lip syncs the lyrics that we all know way too well, before it cuts to a clip of Hawk skating.

But while the Canadian pop singer looks like she hasn't aged a day, a lot has been going on in her public and private life.
Here's what Avril Lavigne has been doing since her 2000s heyday.
Just like her career, Lavigne's relationships have also dominated the headlines over the years.
The singer was just 19 years old when she started dating Sum 41 musician Deryck Whibley. The pair were together for a couple of years before they tied the knot in 2006.
Unfortunately, their marriage didn't last long. And just three years later, they filed for divorce.
The 'Girlfriend' singer later moved on to Nickleback front man Chad Kroeger, who was 10 years her senior.
