Miley Cyrus Kicks Avril Lavigne’s Canadian A$$

In case you haven’t been following, Miley Cyrus took her Bangerz tour to Canada last night. And although the concert was a big hit, one Canadian pop star wanted to make sure to put Miley in her place…

You guessed it! Avril Lavigne paid the “We Can’t Stop” singer a visit to let her know she still remains the most famous person in Canada, despite Miley being there.

When Avril starts to get a little bit catty while protecting her territory, Miley wasn’t afraid to let loose, throwing a few b*tch slaps and even more expletives her way.  Luckily for us, it was all caught on Instagram:

LOL.  Shall we chalk it up to a good ol’ April Fool’s joke?

Either way, bravo to the pop princesses for giving us all a good laugh.  After such a great collaboration, now I want to know when they’ll work together musically!

So what do you think?  Who’s the most “famous, beautiful & popular in Canada,” Miley or Avril?
