Yes, yes. I know. More people bought albums back then. Whatever. It's still funny.
Avril = 36 million albums sold.
Katy Perry = 11 million
Rihanna = 15 million
Lady Gaga = 27 million (technically only 22 million since The Fame Monster is not an album)
Ke$ha = 3.5 million
Justin Beiber = 15 million
Taylor Swift = 22 million
Adele = 29.8 million
I'm not bragging, but the next time you get into a fan war, you can tell whoever else that Avril is the queen.
