Avril Lavigne has revealed how she invited Marilyn Manson to her house in the middle of the night, to record their duet Bad Girl.
The 28-year-old singer and the 44-year-old goth rocker collaborated on the track on her new album.
Avril told MTV: "It was last minute, 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."
The Sk8r Boi singer and the Sweet Dreams singer apparently met at one of his concerts when she was 18 and last year Marilyn confessed they had dated.
Avril revealed he hadn't just brought out her inner bad girl in her music, but also encouraged her to rebel by shaving one side of her head last year.
She said: "I had wanted to shave the side of my head for quite some time, and I used to put it in a braid there, and so it was kind of like shaving it.
"And then one night, it was on my adventure to France. During my adventure when I was living there, we were hanging out backstage and we were with his band having a few drinks and I was like, 'Let's shave my head. I'm ready; let's do this!' He's like that, though. He has fun. He wears his make-up; his wardrobe is very visual. I like his style."
Avril is currently planning her wedding to Nickelback rocker Chad Kroeger.
