This industrial grinder finds Lavigne teaming up with Marilyn Manson. The Canadian singer told Billboard magazine that she first met the shock rocker at one of his gigs when she was just 18. "I went to one of his shows and we hung out backstage," she recalled. "We were friendly over the years. And then I wrote this song called 'Bad Girl' and it's darker and heavier; it's one of the rock tunes on the record, so I called him up."
Lavigne revealed to MTV News that the collaboration with Marilyn Manson was completely unplanned. "It was last minute," she said. "I was sitting there at the board thinking Manson would be perfect on this track, so I texted him, and he's like, 'I'll come over and I'll hear it.' So he came at 4 o'clock in the morning. Yes, it was one of those nights."
