Avril Lavigne + Marilyn Manson ‘Bad Girl’ Collaboration Leaks

There's a collabo we never saw coming: Avril Lavigne and Marilyn Manson! The Canadian faux punk and the 'Dope Show' rocker teamed up for 'Bad Girl,' a sexually charged anthem from her upcoming self-titled album.

Manson opens the track with a dark come on, snarling, "Just lay your head in daddy's arms / You're a bad girl." Lavigne returns some demands, growling, "Stroke me because I said so / Stroke and feed my ego / I've been a bad girl." Alrighty then!

Manson provides predominantly background vocals on the track, with the 'Goodbye Lullaby' singer holding her own for the rest.

The song is a stiff departure from her duet with husband and Nickelback frontman Chad Kroeger, with whom she collaborated on ballad 'Let Go.' Listen to 'Bad Girl' below and let us know who you think wore more eyeliner in the studio -- Av or Marilyn!
