The 24-year-old singer, who has previously revealed that she wanted to be a witch when she was younger, said that it would be 'fun' to add a gothic edge to proceedings.
She told the Daily Star, 'It would be fun to get shamans' robes for everyone while we're recording.
So everyone – the whole band – gets dressed for work, puts on their big robe, and comes down to the studio.'
And she said that her interest in all thinks spooky is still very much alive and kicking.
'I love séances, witchcraft, heaven and hell, voodoo, gospel, possession, demons, exorcism and all that stuff,' she said. 'I'm not a religious person. Sex, violence, love, death, all the topics that I'm constantly wrestling with, it's all connected back to religion.'
