Our favorite online April Fool's joke came from an unlikely source yesterday: The Instagram account of Avril Lavigne. In a series of photos and one video, the Canadian singer argued with Miley Cyrus and got into a full-on brawl. "Oh hey Miley, I'm actually the most famous person in Canada," Lavigne tells Cyrus, who is sitting and reading about Avril. Miley, wearing a full-on Rasta onesie with a cannabis leaf retorts, "I may not be Canadian, but I'm the most famous person in Canada."
And then a hilarious catfight ensues! Click here to see the full video.
