Miley Cyrus Bitch Slaps Avril Lavigne in Hilarious Catfight Video

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."
