Avril Lavigne's look hasn't really changed much since 2001, but she has made some attempts to showcase a more mature side — most recently, "Bad Girl," her collaboration with Marilyn Manson. Though the song isn't particularly groundbreaking (it sounds a lot like Avril's other heavier tracks, albeit with a a bunch of metal groaning courtesy Manson), the lyrics are bound to raise some eyebrows.
The song opens with Manson creepily moaning "Just lay your head in daddy's lap, you're a bad girl" before transitioning into verses in which Lavigne sings about being a "little tease" who wants it, "pretty please." It is SO GROWN UP. And may make you want to throw up.
