Hello Kitty's Unlikely Place in Rock

On Nov. 1, Hello Kitty turns 40 years old — with a four-day celebration, Los Angeles's first annual Hello Kitty Con, taking place in her honor Oct. 30-Nov. 2. It's hard to believe this ageless feline (who may or may not really be a feline) has already been rocking that red bow for four decades now. What's her secret to eternal youth? Well, they say music keeps you young, and thanks to some famous fans, Hello Kitty has definitely led a rock 'n' roll lifestyle since the swinging '70s.

To celebrate the Sanrio icon's big 4-0, we've assembled a retrospective of the best Hello Kitty/music mashups in pop history. (No, Avril Lavigne's atrocious "Hello Kitty" video did not make the list.) Happy big birthday, HK!
