Miley Cyrus Bitch Slaps Avril Lavigne in Hilarious Catfight Video—Watch the NSFW Clip!

Singers playfully duke it out while trying to figure out who is the most famous person in Canada

Who is the most famous person in Canada?

Well, Miley Cyrus and Avril Lavigne playfully tackle that very question as they jokingly fight—both physically and verbally—in this NSFW video that Cyrus posted on Instragram.

In other words, they don't exactly agree on each other's answers.

Cyrus, while sitting backstage in her dressing room following a show at Toronto's Air Canada Centre, is confronted by Lavigne, who says, "Oh, hey, Miley, I'm actually, like, the most famous person in Canada."

The "Wrecking Ball" singer proceeds to stand up and snaps, "I may not be Canadian, but I'm the most famous person in Canada, ya dumb f--king bitch."

The clip ends with the the two gals getting into quite the catfght!

Obviously, this little collaboration was done for laughs.

Now, if we could just get them to join forces musically, that would be pretty cool.
