Avril Lavigne

Remember when Avril Lavigne beat out Justin Bieber for the title of most famous Canadian? Miley Cyrus sure does, and she's jokingly pissed that she didn't land the No. 1 spot -- even though she's, um, not even Canadian. The 'Wrecking Ball' singer is so annoyed, in fact, that she hilariously duked it out with the reigning champ herself during her Bangerz Tour stop in Toronto last night (Mar. 31). 

Backstreet's back, alright! Nick Carter, AJ McLean, Brian Littrell, Kevin Richardson and Howie Dorough made an exciting announcement this morning on 'Good Morning America' -- the band is extending their world tour and coming back to North America this spring!

Avril Lavigne was performing her power balled 'I'm With You' in China when she stopped, emitted a little shriek and then ran off the stage. What happened?

When Avril Lavigne finally gets around to joining Instagram, she makes sure people notice. For her first-ever post today (Aug. 8) on her brand-new account, the singer revealed the cover artwork of her upcoming, self-titled album.

The 2013 MuchMusic Video Awards were rife with pop performances and huge names. Stars like Demi Lovato, Avril Lavigne, Phillip Phillips and Ed Sheeran all joined forces with co-host Psy to rock the stage in Toronto, Canada.

Avril Lavigne proved she really is never growing up at Wango Tango 2013.

KIIS FM held its annual Wango Tango concert on Saturday, May 11. Britney Spears, Demi Lovato, Avril Lavigne and many others walked the event's orange carpet, looking faboosh!

Today, April 29, in music history we go back to 2007 when singer, songwriter, musician  Avril Lavigne made music news.

Avril Lavigne rocked her grows-on-you new single 'Here's to Never Growing Up' on 'The Tonight Show With Jay Leno' on Friday (April 26). The Canadian angst queen was a little restrained in her performance, remaining largely immobile and perched behind her microphone stand. But the fact that she remained stationary didn't lessen the impact of her vocal delivery.

Avril Lavigne performed at the Viper Room in Los Angeles last night (April 25), performing old favorites ('Complicated,' 'Girlfriend') and new tracks ('Here's to Never Growing Up'). She also debuted a brand-new, never-before-heard song called '17.' Can you guess the subject matter?
