In photos: Avril Lavigne's dramatic style transformation

Proud Canadian! Avril Lavigne attended the 2002 MTV Video Music Awards while reppin' the Great White North on her signature tie.

Avril made a fresh and glamorous entrance at the Chanel Couture show during Paris Fashion Week in January 2006.

Introducing her Abbey Dawn collection during Style360 in New York, Avril took the catwalk by storm in 2009.

Avril sported a signature Abbey Dawn hoodie as she was spotted on her way to Siren Studios in L.A. in 2010.

Hanging out with pal Kim Kardashian at the record release party for “Goodbye Lullaby" in 2011, Avril showed off her signature style in a black tutu and Doc Marten boots.

Avril and future-husband Chad Kroeger are a perfect pair as they were spotted going for a romantic stroll in Paris in 2012.

Avril showed off her curves in a leather green dress for her performnance on Extra in September, 2013.

The 29-year-old songstress chose a Brian Rennie for Basler peplum gown for the 2013 Huading Awards, which featured optical-illusion black side panels that showed off her curvy figure.

Shortly after her fifth album debuted, the songstress performed on Good Morning America, where she wore a bold tartan dress and Kate Middleton-inspired heels.

At the annual Jingle Ball last year, the Canadian songstress chose a long-sleeved zippered mini-dress, which she paired with sky-high black pumps.

Rocking leather pants and a pink tartan dress, Avril has clearly branched out from her tomboy look while still maintaining her signature "pop punk" aesthetic.

The singer pays homage to Japanese culture with her new single "Hello Kitty," a bubblegum-pop-meets-electro track, which even features a dubstep-inspired drop. Avril's stage outfit reflects the kooky new sound.

After a private battle with Lyme Disease, Avril made her return to the stage in the summer of 2015 at the Special Olympics World Games, where she rocked an embellished black gown to debut her inspirational new song "Fly."
