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.

Striking a pose TRL in 2004, Avril inadvertently started a black-and-blond hair trend.

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

Lavigne looked lovely on the red carpet at the premiere of 'Over the Hedge' at Cannes in May 2006.

The Punk Princess celebrated the launch of her album, 'The Best Damn Thing,' in April 2007.

Avril donned a schoolgirl-chic ensemble while singing “Girlfriend” at the 2007 Teen Choice Awards.

Golden Girl Avril shone brightly at the 2007 American Music Awards in a strapless metallic gown.

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 reigned on the 2013 MuchMusic Video Awards red carpet, wearing spiky metal crown.

Avril can have her cake and eat it too!

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.
